Why y'all should trust us
Since 2014, we've spent more than than 420 hours researching and testing dozens of humidifiers in enclosed home spaces using Lascar data loggers. The earliest versions of this guide were written by John Holecek, a former National Oceanic and Atmospheric Administration researcher who has studied atmospheric physics and chemistry everywhere from the continental Usa to the Arctic to the remote island nation of the Maldives. Senior staff writer Tim Heffernan took over in 2017, edifice on that before research. Tim has also written guides to air purifiers, water filtration systems, and more than. Since 2019, the guide has been shepherded by staff author Thom Dunn, whose other work includes guides to space heaters, portable air conditioners, and window air conditioners.
Who this is for
If you are bothered by problems associated with dry air—dry sinuses, nosebleeds, cracked and sore lips, or shocks from static electricity—the air in your habitation is probable under-humidified. In most of the US, this is primarily a winter problem, specially in homes with forced-air heating systems, which tin bulldoze indoor humidity down to desert-like conditions. Only dry air tin can also be an issue if you take radiators or other types of heating, since the relative humidity of cold winter air is generally lower than that of summertime air.
The cheapest and easiest way to keep the relative humidity levels at levels recommended by the EPA—beneath 60%, and ideally between 30% and 50%—is to utilise a humidifier. This will convalesce the symptoms listed in a higher place while discouraging mold and mildew growth (which tin can happen in excessively humid conditions). Proper humidification can likewise aid tedious the spread of airborne viruses, including influenza and SARS-CoV-2, aka the coronavirus. The full general research consensus is that even though a humidifier should never be relied upon to foreclose infection, ambience humidity matters (to a caste) in terms of a viral particle'southward ability to survive in the air, as well as in how your immune system'south defenses part. Medical enquiry we've seen that describes how to use a humidifier to create optimal conditions echoes the EPA'southward long-standing thirty% to 50% advice. If y'all want to measure the humidity in your space earlier you lot purchase a humidifier, or you want to monitor the operation of a humidifier you already have, yous tin become a basic hygrometer on Amazon for about $ten.
Humidifying your domicile involves more than just ownership a machine and keeping it filled with water. Neglecting to clean and maintain your humidifier, often on a weekly basis, tin can expose you to health risks, similar the nasty fungal wheezing of hypersensitivity pneumonitis, also known as "humidifier lung." At that bespeak, the machine tin can exercise yous more harm than good. You tin can mitigate this risk somewhat past using distilled or demineralized water instead of tap, but either mode, you lot'll still have some work to do. So ask yourself honestly: Are you ready to be a "humidifier parent"?
How nosotros picked
This is the eighth iteration of a guide we've been working on for nearly a decade, then nosotros went into it with considerable noesis on what constitutes a good humidifier, in terms of technology and pattern. Measured strictly by moisture output, most of the machines we've tested over the years accept performed adequately. But we've plant huge differences in ergonomics, ease of cleaning and filling, quality of construction, and user interface.
Because you generally have to interact with a humidifier daily (to refill the tank, sometimes more than in one case, and then restart and reset information technology), these factors ever weigh heavily in our decision on which machines to pick for testing.
As always, we researched popular models on Amazon (paying attention to both positive and negative reviews), as well as sites like AllergyBuyersClub.com, Top Ten Reviews, ConsumerSearch, and Best Buy. And we read the comments from our previous guide for feedback and suggestions from our readers. We focused on portable humidifiers rated to cover betwixt 200 and 700 square feet. Nosotros limited our search to models that needed to exist filled simply once a day, which meant a minimum tank size of 1 gallon (although nosotros have fabricated occasional exceptions).
There are many different kinds of humidifiers, only we narrowed our search to the almost common types: evaporative and ultrasonic. Neither i is necessarily better than the other; they're both simple, effective, and energy-efficient machines that use different methods of humidifying a room. In the past, our top pick has typically been an evaporative model; these tend to have a more mechanically simple design, and they are better at cocky-regulating, often shutting themselves off as shortly equally they enter the platonic humidity range. Over fourth dimension, withal, in response to reader feedback, we've started leaning more heavily toward ultrasonic models. These tend to be quieter than their evaporative counterparts, and they don't demand whatever wicks or filters that require regular maintenance. But they're also more than likely to over-humidify the room, and they can sometimes leave a dusting of fine white powder on the floor from the minerals in your water. (This is more than of an annoyance than annihilation else, and y'all can minimize the trouble past using distilled or demineralized h2o.) Still, we always make sure we offer recommendations for both kinds of humidifiers, then you lot can choice which one suits your situation meliorate.
Over the years, we've considered more than 100 different humidifiers and tested more than two-dozen of them. For our near recent tests, in 2021, we looked at three new ultrasonic models: the Carepod One, the Wi-Fi–connected Levoit Classic 300S, and the Dyson–PH01 Pure Humidify + Cool (which doubles as an air purifier, only nosotros didn't test this characteristic). We also looked at two new evaporative models, both from Vornado: the "Energy Smart" EVDC300 and the actress-large Evap40. We compared these against our existing picks: the evaporative Honeywell HCM-350 Germ Free Cool Mist Humidifier, the ultrasonic Honeywell HUL430 Cool Mist Humidifier, the Levoit LV600HH, and the Venta LW25 Airwasher (which uses a unique cold-evaporation technology and claims to "launder" or purify the air).
How we tested
Our testing procedures have remained largely the same since 2014, although the locations have inverse. We set up the exam models in an enclosed, 200-square-pes room with the windows shut tight and the forced-air or other HVAC equipment deactivated. We take an initial humidity reading, plough on a humidifier, let it run for four hours at a time, and repeat—outset on medium (or depression, on 2-speed machines) and then again on loftier. The aim is to measure the humidifiers' performance nether everyday conditions (when the medium setting would be acceptable), besides as under challenging weather (such as during a tour of uncommonly cold, dry winter air, when humidification needs are highest). Between tests, we reset the conditions by opening the windows, turning on a dehumidifier, and circulating in drier air.
While running these tests, we mensurate quantitative factors to provide a mutual baseline of comparison among the models. We track the rate of humidification in the room as well as the accuracy of the humidistats, and other climate-based data, using a pair of Lascar high-accuracy USB data loggers. For volume measurements, we use an audio spectrum analyzer app, recording our results in both dB-A and dB-C frequency weightings for added accurateness.
We likewise pay attending to qualitative factors, like the ease of cleaning the machines, the simplicity of operating them, and other details that make living with them as easy as possible. We note any difficulty opening, filling, and closing the tanks; this tin can be a pretty crucial factor, since most machines get refilled at to the lowest degree once a day, if y'all run them constantly on a medium setting. Admittedly, our observations are subjective—simply scrubbing a dozen humidifier tanks, filling them twice daily, and carrying them across a ane,200-square-foot apartment (over and over) all week does breed some familiarity.
Our most recent tests were performed in the fall, in a garden-level Boston apartment with electric radiator estrus. From 2017–18, we tested in a New York City apartment that had hot-water radiators. Before that, we tested these machines in lab-like conditions at the home of John Holecek, a former NOAA atmospheric scientist. And all the while, nosotros take used these picks long term throughout the country in Wirecutter staff members' homes.
Our pick for the best humidifier: Levoit Classic 300S Ultrasonic Smart Humidifier
Our pick
Of the more than than two-dozen humidifiers we've tested over the years, the Wi-Fi–connected Levoit Classic 300S Ultrasonic Smart Humidifier offers the all-time combination of easy maintenance and quiet, reliable performance. It's also the first ultrasonic model we've tested that was actually able to stop itself from over-humidifying a room—a surprisingly monumental feat. The 6-liter tank is large plenty to terminal a whole day, and it is easier to open, make full, and clean than almost whatever other tank nosotros've tried. The Classic 300S besides has a born nighttime-low-cal, forth with the option to turn off both the light and the digital LCD screen, depending on how y'all like to slumber. Thoughtful features like these make the Classic 300S more pleasant to live with overall, and they can all exist controlled by four capacitive buttons on the unit itself or via app or voice command. Even the smartphone app was surprisingly delightful. And though initially nosotros were pretty skeptical about the idea of a "smart humidifier," it won us over with its remarkably user-friendly pattern, which genuinely made our lives easier. When it comes to humidifiers, "ease of living" is really the ideal.
In our tests, the Levoit Classic 300S stood out not simply for its power to speedily humidify a room simply also for its rare ability to stop itself from humidifying a room. It performed impressively when we chose to let it run without limits, raising the relative humidity in the room past nearly 30% in just over two hours—making information technology more powerful than any other humidifier we tested (with the exception of the Carepod). Ultrasonic-mode humidifiers are infamous for over-humidifying spaces, transforming the air from a pleasant mist into a damp fog—which is exactly what happened in that beginning test. Then nosotros ran a 2nd exam with the Classic 300S using the default "auto" setting. Over the course of four hours, this model brought the relative humidity in the room from 52% to about 55%. This was precisely what nosotros wanted the Classic 300S to exercise. Information technology was precisely what the didactics transmission said the Levoit would exercise. And it's something that no other ultrasonic humidifier has e'er actually done for us. Past dissimilarity, the auto characteristic on the Levoit LV600HH—a model we've been recommending since 2018—sometimes won't stop until the room has reached the steady dankness of ninety% relative humidity. This is non only uncomfortable but also potentially dangerous, because this level can encourage mold growth and other nasty things. In other words, the Levoit Archetype 300S stands out both because it humidifies a room better than other models and likewise because information technology doesn't.
As do other ultrasonics, the Levoit Classic 300S emits a low mechanical hum that essentially disappears within the empty audio of every room. The discussion essentially here is key—y'all might still discover the hum if you're in an uncommonly quiet place, such as a forest with no wind or critters. Some owners find this sound to be more than irritating than the white noise made past evaporative humidifiers. We personally take never been able to hear whatsoever sound from the Levoit Archetype 300S, but people with sensitive hearing (or those who haven't spent decades playing in stone bands) might be more than attuned to these things. The buttons don't make whatsoever sounds when you lot touch them, either, which is really a squeamish surprise (the buttons on the Levoit LV600HH emit a ping!, which isn't atrocious on its own just is still loud enough to wake some sensitive sleepers).
The Classic 300S'south aesthetic simplicity is another big part of this model'due south appeal. It's just a slightly tapered rectangle with rounded corners. At that place's a base of operations unit of measurement on the bottom with a h2o reservoir, every bit well four capacitive controls and an LCD screen, with a tank resting on tiptop. That's all information technology is, and that's all you actually need. When the time comes to fill or make clean the Classic 300S, you can lift the 1½-gallon tank directly off the base and carry it with the two born handles. Other humidifiers (including the Honeywell HCM-350, our former top pick, and the similar Levoit LV600HH, which is still an too-keen choice) utilize spiral-on lids to keep the water in the tank. But these can sometimes exist difficult to open, especially for people with paw-mobility issues, or even simply if they get likewise moisture to grip right. Past contrast, the lid on the tank of the Archetype 300S lifts directly off without any twisting or latching. The opening on the Archetype 300S spans the width of nearly the entire tank, every bit well, so it's easy to fill up and even easier to reach inside and scrub abroad the inevitable limescale buildup. The only awkward part is the chimney where the water vapor passes through, which is hard to get into even with a bottle brush or the included cleaning tool. At that place are also a few plastic pieces that stick out on the bottom of the tank, but the tank should nevertheless exist able to balance well enough in most sinks. You do have to hold it while you're filling the water or, worse, awkwardly balance it against something and hope information technology doesn't spill.
The base unit of the Archetype 300S has iv basic buttons. These should provide yous with all the controls you'll demand, without having to remote-control annihilation with the app (although the app does allow you dial in with more precision). The ability push turns on the unit and the LCD screen. The "mist level" button toggles the humidification output betwixt low, medium, and loftier, or it lets yous set up the unit of measurement to auto-regulate itself. There'due south also a small dark-light inside the tank, and you tin can switch it on or off with the calorie-free bulb push button (this is a nice feature if y'all desire some gentle illumination in the darkness). Finally, there's a "slumber" button, represented by a crescent moon, that turns off the LCD screen only keeps the unit of measurement running—a thoughtful bear on for those (like my infant son) who need total darkness to sleep. When the LCD screen is lit, information technology displays the exact humidity level in the room, and information technology too indicates other things like Wi-Fi connectivity, depression h2o levels, and whether or non you've set a timer in the app. It'south a pretty basic digital display, but it gives you but plenty options and information without overwhelming you.
If you practise want more-precise control, or you want to adapt the humidity level for that "auto" setting nosotros retrieve works so well, the Levoit's smart app, VeSync, provides you with plenty of options. On a bones level, it works every bit a elementary remote control so you can command the LCD display, night-light, mist level, and then along, without having to leave the burrow or bed. The app also lets y'all create a schedule to run your humidifier, to set a timer, or to customize the auto setting'southward Target Humidity. The app's default target is set to fifty% (which is what nosotros saw in our tests), and it also has an "auto-off" mode, which is turned on past default. This auto-off setting automatically stops the auto when the humidity reaches 5% above your target humidity, and the setting starts the machine when your target humidity drops more than 5% below your target humidity. You can customize these levels in the app, though we're non sure why you'd want to. The app volition too requite you weekly cleaning reminders (if you desire them), and you can even create custom smart scenes based on personalized "if this, then that" scenarios, which is pretty keen. We were also impressed with VeSync's smart-dwelling house integration. Non just does the app actually tell you what kind of voice commands you lot can utilize, it will also automatically search your phone (with your permission) to sync upwardly and connect with Alexa or Google Abode (bold y'all have the apps installed on your phone). Yous don't even have to open up a carve up app to make certain everything is synced. That kind of convenience is rare, simply it's the type of thoughtful item that makes the Levoit Classic 300S stand out.
Long-term test notes
Several Amazon reviewers accept complained virtually the tank on the Levoit Classic 300S leaking — and after a few months of regular apply, we started noticing a like problem ourselves. Some Amazon reviewers have specifically pointed out an upshot with the rubber stopper on the bladder valve, which is supposed to close when the tank is full, then push up to fill the base with water equally needed. While we didn't take this specific trouble ourselves, we still noticed that the tank would still baste every time we lifted it to refill. As far every bit we could tell, these drips were but on the surface—not from an actual ho-hum leak, but from lifting information technology out of a basin of h2o. We'll continue an eye out on this watery weirdness issues, and continue to update this guide as nosotros larn more.
Flaws but not dealbreakers
Like a lot of ultrasonic humidifiers, the Levoit Classic 300S has a circuitous water channel in the base of operations unit of measurement, and this tin be a little catchy to clean. Although it's not as labyrinthine as those of other models we've tested, you may nevertheless demand to go far in that location on occasion and actually scrub for a while. The educational activity manual (PDF) should offer some guidance for whatsoever other tricky situations.
Among the user reviews, you as well run across people referring to leaks from the tank. We haven't experienced anything unusual in our tests of this model. And we should note that a smattering of the one-star reviews mention leak bug common to most humidifiers we've evaluated.
Finally, it bears repeating that although nosotros're big fans of smart-home integration, we were initially skeptical of a Wi-Fi–connected humidifier. It but felt unnecessary. Even though we were surprised to find that the VeSync app genuinely made our life easier, nosotros were nevertheless frustrated by the fact that nosotros had to download an app and create a new password to log in to a humidifier. In that location are plenty of user reviews complaining almost the potential personal-data bug hither, every bit well. The VeSync app (named for the parent company of Levoit) is designed to work with several other brands, such equally Etekcity and Cosori, and it too serves as an online store and a customer service hub. The visitor'due south sprawling privacy practices comprehend products ranging from smart scales to foot massagers, making them even more hard to parse, let lone verify. Suffice to say we were not pleased to learn that VeSync had automatically signed us up to receive e-mail marketing that we never explicitly agreed to. Nosotros were comforted to know that the company instituted a issues compensation program in 2021, which allows security researchers to study bugs they notice for greenbacks rewards. The program is still new, just nosotros'll keep an eye on how the visitor reacts to submitted bugs. Nosotros've reached out to the company for additional clarity on a few other information-related questions, and we will update this guide when nosotros take more information.
Also, it'south really abrasive that yous have to remember the name "VeSync" when y'all're looking for the app on your phone, rather than the more obvious "Levoit." The seafoam-dark-green icon with a vague image of a house bisected with half an infinity symbol doesn't really scream "humidifier," either.
A reliable, depression-maintenance option with warm mist: Levoit LV600HH Hybrid Ultrasonic Humidifier
Runner-up
We've been recommending the Levoit LV600HH Hybrid Ultrasonic Humidifier since 2018, and we withal think it's a great choice, specially for large spaces like a living room–dining room and exceptionally dry out homes. Its accurate digital humidistat maintains the humidity at your desired level (although we suggest that you lot disregard the "auto" setting—more on that afterwards). Overall, the LV600HH is just like shooting fish in a barrel to alive with. Information technology's quiet and relatively unproblematic to clean, and the lighted display tin can be shut off and so it won't disrupt anyone'due south sleep. This is also the merely model we recommend that has a warm-mist option. We're kind of ambivalent virtually this characteristic for a number of reasons, merely if information technology'due south something you lot want or need, then this Levoit is the way to go. Our primary caveats are the same ones we take with most ultrasonic humidifiers: They tin over-humidify your room or leave a misting of minerals on the furniture (a common issue with well water, and particularly in the mountain states). And though the tank itself is like shooting fish in a barrel to clean, the base of operations unit has lots of nooks and crannies that make it fussier to maintain than the Levoit Classic 300S, our top pick.
In our real-world tests, the LV600HH has consistently placed at or near the top in overall humidification year after year. And different those on many other models we've tested, the LV600HH humidistat actually worked, tracking within five points of what the data loggers registered. That means you lot can manually set a target humidity, and the machine will plow itself on and off to continue the air at that level. The LV600HH does have an "automobile" setting. But we learned the difficult fashion not to let the machine decide the best humidity level—having woken up more than in one case in a literal fog of more than 90% humidity. Though the LV600HH does come up with a remote control, information technology doesn't apply an app like the Classic 300S does. And so you don't have every bit much control to fine-melody things, such every bit that inconsistent "auto" setting.
The LV600HH's 1½-gallon tank is similar to the tank on the Levoit Classic 300S. And it can run for a long fourth dimension between refills (the company claims a vague 10 to 60 hours; we've gotten almost 27 hours with the car running continuously on medium, which is about what we expected). This capacity makes both Levoit models adept options for very large rooms or overly dry out homes, such as those with forced air or wood heating in the winter. We also appreciate the fact that the tank can lie flat while you're filling it (which, because it's 6 liters, can take a while) and that the tank's fill hole is easy to hit from the faucet. The opening isn't as large as that on the Classic 300S, just it'due south nevertheless big plenty that yous tin reach inside to practice a thorough cleaning (you lot may, however, find it'southward a little uncomfortable to reach your arm inside to scrub the corners of the rectangular tank).
Like most ultrasonics, the LV600HH is also essentially quiet. Nosotros measured 38 decibels at three feet on low, medium, and loftier settings. Unlike with a lot of other models, however, with the LV600HH you can shut off the bright display at night by belongings downward the (otherwise useless) auto button for a few seconds. This makes the LV600HH a particularly nice choice for a bedroom or a plant nursery, compared with machines nosotros've tried that have lights or screens that are ever on (although an ambitious/curious toddler can withal mess with the controls, even when the screen is off).
Ane downside specific to the Levoit LV600HH (beyond the drawbacks common to all ultrasonic humidifiers) is the complex water channel and chimney in the base of operations unit of measurement. There are a number of tight nooks and crannies where gunk can accumulate. Cleaning them isn't difficult—a small castor actually helps, along with a white-vinegar soak—but information technology'due south needlessly tricky. The cap to the tank is also slippery and hard to open when wet (which it e'er is when you pull the tank off the machine to refill it). Using a towel to grip the cap helps, just that's an actress pace; a toothier texture on its rim would eliminate the problem.
Finally, there'due south the LV600HH'due south warm-mist office. This works fine. Only because warm mist is energy-intensive, involves hot parts that tin can potentially scald, and doesn't really humidify whatsoever better than other methods, we don't recommend using this function. If you consider information technology a must-have feature, though, the LV600HH is probably your best choice.
Basic, quiet, affordable: Levoit Archetype 200 Ultrasonic Absurd Mist Humidifier
Budget pick
If you want an affordable, bones, quiet, attractive humidifier, go for the Levoit Classic 200 Ultrasonic Cool Mist Humidifier. Ane of this model's main limitations is in that location's almost no discernible difference betwixt its settings, other than the color on the LED indicator. That'south in improver to the common ultrasonic tendency to over-humidify. All of that may be fine if you lot feel you can alive without a versatile, detailed humidistat.
Despite its unproblematic features, the Levoit Archetype 200 provided some consistently powerful humidification—about a 13% humidity increase in the first 60 minutes, and an average increase of 24% over the course of four hours. Levoit claims the water in the tank can last upwardly to 40 hours on low or ten hours on high. Simply like most ultrasonic models, this model can over-humidify the room if it runs for likewise long. In our tests, information technology ultimately turned the bathroom into a clammy sauna, with an 84% relative humidity level that made the porcelain glisten.
The Levoit Classic 200's four-liter tank is smaller than the tanks on our other Levoit picks, but the surprisingly large fill hole makes information technology easy to clean. The tank is rectangular, and so information technology's easy to fill and able to stand up on its own. Where most of the other models we tested take a spiral cap to shut the tank, the Levoit Classic 200 has a i-twist cap lined with a condom gasket. We found this nerve-racking at showtime, but it worked well plenty. However, there is a fake "lid" that rests loosely on top of the cap, which is easy to forget near, and accidentally send crashing to the ground when you lot're trying to transport the tank; it'due south a mistake nosotros continue to make, even after living with this humidifier for a while. Luckily, the water doesn't spill when this happens, even if information technology is a little jarring. This Levoit model besides includes a tray for essential oils.
An energy-smart evaporative alternative with great circulation: Vornado EVDC300
Also swell
If you lot desire a humidifier with meliorate circulation that won't over-humidify the room, or yous simply desire something that uses even less energy than our ultrasonic recommendations, the Vornado EVDC300 is a reliable choice. Different our other picks, the EVDC300 is an evaporative humidifier, which means it uses a replaceable wick or filter and pushes the freshly dampened air out through a fan. Though this does mean it's slightly louder than our ultrasonic picks, the sound is not unpleasant; we think it's a fair merchandise-off to end upward with a more than-even distribution of humidity throughout the room. Vornado has a well-deserved reputation for air circulation—nosotros also recommend a number of its room fans and space heaters—and the EVDC300 is no exception. This detail humidifier besides has a DC motor, which makes information technology more free energy-efficient in general. It also has a dedicated "Energy Smart" mode, which uses equally little equally 1 watt of free energy, instead of the 8 to ix watts it normally pulls. Otherwise, the EVDC300 is nearly identical to 1 of our previous Vornado picks, the EV100. And if anything goes incorrect, the EVDC300 is backed past an impressive five-year warranty (the motor itself is guaranteed for 10 years).
The EVDC300 has a uncomplicated capacitive-affect command panel on top of the unit, with five buttons that let you control the power, "Energy Smart" style, and fan speed (LO, Howdy, or HH, which confusingly stands for "turbo"). And they arrange your target humidification level up and downward. The EVDC300 smartly limits this target range to forty% to 60%. There'southward too a continuous-operation setting (displayed equally "CO"), which slows the rate of humidification as information technology approaches 60% simply never shuts the car off entirely. In our tests, nosotros were genuinely impressed by the EVDC300's power to consistently concord the line within near 2% of its target; fifty-fifty after 4 hours on the CO setting, it notwithstanding rarely allow the room get higher up 60% relative humidity, which is about as humid equally you lot should ever desire information technology.
In our tests, the EVDC300 managed to raise the relative humidity in the room by about 10% in the first half-hour, then gradually another ten% over the next hour. Although this might brand the machine sound a lot less powerful than our top pick, the ultrasonic Levoit Archetype 300S, that's not entirely the case. Equally an evaporative humidifier, the EVDC300 is designed to automatically cocky-regulate to forbid itself from over-humidifying the room. This means information technology will slow downwards the rate of humidification every bit it senses the room approaching a relative humidity of 60%, and that'south exactly what it did in our tests. This actually makes your life easier because you don't take to worry well-nigh any mold or mildew starting to fester in the dankest corners of the room.
The EVDC300 also had the most consequent humidity readings across the room, thank you to the Vornado fan's singled-out air-circulation ability. Although well-nigh of our test data was based on readings from about 4 anxiety away from the humidifier, we also kept a second monitor in the corner of the room (about 8 feet away, in the contrary direction) to see how well the humidity was dispersed. Unlike every other model we tested (which usually had a discrepancy of about v% to 10% relative humidity betwixt the ii readings, as we expected), the EVDC300 kept the whole room within a few percentage points of the same humidity level at all times. The EVDC300 also made the room feel more pleasant overall, with a gentle, constant waft of freshly humidified air.
However, that impressive Vornado fan also means the EVDC300 is louder than our other picks, which are all nearly silent ultrasonic models. It sounds slightly different than other evaporative humidifiers we've tested, as well, emitting a slightly more high-pitched sound with a slight hissing, gurgling, or bubbling underneath the whir of blades. Basically, it sounds like a modest room fan with water underneath it, which, to be fair, it is. Nosotros personally observe that kind of white noise tolerable, even pleasant, and it easily blends into the background. We measured the EVDC300 at about 51 decibels on its lowest fan setting; this is 9 decibels quieter than what'due south considered "boilerplate" conversation tone. The noise is slightly more pronounced on the higher settings, merely even so, information technology measured but 55 decibels. But if you're accepted to ultrasonics, or even the more "normal" sound of other evaporative models, you may be a piddling startled when you commencement plow on the EVDC300.
The EVDC300 has a ane-gallon tank that lies flat in the sink while you lot fill it. Although this is smaller than our pinnacle pick'south tank, which has a 1.5-gallon capacity, we remember it should all the same be enough to get you through most of a 24-hour interval earlier you accept to refill. The tank also has a convenient conveying handle on top that makes it easy to ship. Instead of a spiral top, however, it uses a rubber gasket that locks into place with one twist. The tank is also cylindrical, with an opening that spans the whole circumference. So it'south easier to reach in and clean it than tanks on almost any other model we've tested, except for the Carepod. It doesn't even have any bad-mannered corners or cut-outs to scrub effectually; it's literally just a tube. That as well means the tank is pretty tall; this could go far difficult to fill up all the way in a shallow sink, like y'all'd discover in a bathroom. Also, the tank is not shatterproof. We learned this the hard manner when a water-loving toddler pushed it off the kitchen counter when it was total.
If anything does go wrong, the unit of measurement equally a whole is supported past Vornado's impressive five-year warranty; the motor itself is guaranteed for a whopping ten years. By comparison, all of our other picks have just a ane-twelvemonth warranty. You'll still need to periodically replace the wicking filter. But the EVDC300 has a subscription pick, which can relieve you money and deliver the replacements correct to your door. And then you actually replace them when yous're supposed to. (These wicks require some additional cleaning maintenance betwixt replacements, every bit well.)
We have i other complaint. The base holds virtually an inch of water all the way around, much of which is subconscious underneath the fan and other electronics. It also has two notches on either end that seem like convenient carrying grooves, which deceive you into thinking y'all can carry the base across your habitation without spilling water all over yourself. Spoiler alert: You cannot.
Upgrade pick: Venta LW25 Airwasher
Likewise corking
The Venta LW25 Airwasher performed extremely well in our tests, and it'due south impressively free energy-efficient. But the LW25's high price is worth information technology but if you're willing to pay a lot more than up-front end for lower power consumption and less-frequent refills and cleanings. Your typical humidifier requires a thorough cleaning (wiping down all surfaces and descaling with vinegar) at least one time a calendar week. But for the LW25, Venta recommends simply rinsing the wet parts every ten to fourteen days and using a proprietary antimicrobial additive to keep the funk downwardly. (A ii-week supply, three½ ounces, is included with the LW25, and the replacement canteen holds 35 ounces, so information technology'southward good for over iv months of use. These replacement bottles will run you about $35.)
The Venta LW25 is basically a compact cube, near 8½ pounds and a little more than than a pes in each direction. It works by drawing air over a set of slowly rotating disks. It draws only seven watts on high (about one-sixth the wattage of a typical evaporative humidifier), yet it's extremely effective at humidifying, consistently performing at the peak in our real-world tests. Despite the machine's extreme efficiency and big, 2-gallon tank, Venta still recommends that you pinnacle it off every day to maintain maximum humidifying efficiency—information technology works best when full.
Nosotros were not impressed with its "air washing" abilities. To test whether this motorcar was comparable to an actual air purifier, nosotros used a laboratory-quality bench-tiptop optical particle counter that measured particles in the 0.5- to 20-micron range; we measured airborne-particle concentrations before and subsequently three hours of testing. Groundwork particle concentrations ranged from 65 to 200 particles per cubic centimeter. At the finish of the testing period, the Venta lowered the particle concentration from a starting concentration of 180 particles per cubic centimeter to a last concentration of ix. This sounds impressive until y'all consider that our quondam summit pick, the Honeywell HCM-350 (which made no claims of air purification) got the number downward to xiv in a similar test. For reference, a HEPA-certified air purifier would bring the number downwards to nearly nada in less than half an hr.
What about warm-mist humidifiers?
Warm-mist humidifiers work by heating water until it turns to steam. And that means these models have the potential to crusade burns—from the hot water and steam and from the heating element. Because of that take chances, the Mayo Dispensary recommends confronting using them in homes with children.
When information technology comes to humidifying the air, warm-mist humidifiers are no improve or worse than evaporatives or ultrasonics. But they do utilise a lot more energy. On the other hand, warm-mist humidifiers slightly rut a room, so you could maybe decline the thermostat a compression. The other humidifier types produce a very slight cooling of the room'south air, which you'll need to heat again (via a furnace or other heating organisation).
But do warm-mist humidifiers actually offset their energy costs by lowering your heating bill? John Holecek did a adding in 2015, and the answer was no. Assume the humidifier sees three years of use (for six months each year) and dispenses 4 liters of water per mean solar day of use. Presume the dwelling is heated with natural gas. For energy costs, Holecek used his local California rates at the time of 18¢ per kWh for electricity and $1.20 per therm for gas. The efficiency of both the electrical humidifier (range of 65% to eighty%) and the gas furnace (range of 78% to 97%) was ready at 80%.
By figuring out the energy needed to estrus the h2o from room temperature to near boiling (334 joules) and adding the extra energy needed to vaporize it (2,260 joules), we know the total energy (ii,594 joules) needed per gram of water. Using (and converting) these assumptions, if you heated that water with the humidifier, you would spend a whopping $355 in electricity, versus just $81 in natural gas, to supply the aforementioned amount of heat to your air. Clammy air can feel bad in the winter, and we empathize the appeal of warm-mist humidifiers. Merely producing heat this style doesn't end upwards existence a good bargain.
What near air washers?
For air washers, which claim to remove particles from the air, we measured airborne-particle concentrations at the beginning of the test and later on three hours of running the machines, using a laboratory-quality benchtop optical particle counter that measured particles in the 0.5- to 20-micron range. Background particle concentrations ranged from 65 to 200 particles per cubic centimeter.
Later on running the Venta and the Winix air washers against our former summit pick, the Honeywell HCM-350 evaporative humidifier, we saw the particle concentrations drop for the Venta and the Honeywell simply actually rise for the Winix.
The Venta lowered the particle concentration from a starting concentration of 180 particles/cm³ to a final ix particles/cm³. That'due south not nearly as good every bit the results from the air purifiers nosotros tested for our all-time air purifier guide, only information technology's still an order-of-magnitude reduction. Past comparison, the Honeywell—which isn't marketed equally an air washer but withal pushes air through a wet filter—saw the particle concentration modify, from 65 to xiv particles per cubic centimeter.
The Winix air washer, by contrast, didn't reduce particle counts at all: The counts started at lxx and climbed to 150 particles/cm³ after three hours.
In summary, our accept is that air washers and humidifiers can remove some larger particles (0.5 to 20 microns) like pollen and dust mites, simply not well-nigh as well as a defended air purifier.
What about putting a pot of water on a radiator?
In researching humidification options that don't crave tons of time and attention to maintain, we came across a common DIY suggestion for those who live with steam radiators: Just put a pot of water on it. The thought beingness that the water will heat upwards as the radiator runs, gently steaming the pot and producing humidity without the need for all the care and maintenance of an actual humidifier.
To exam this, one of our writers—who typically dreads turning on the annoying and capricious radiator in his Brooklyn apartment in the wintertime—tried out the method for a few weeks in February and March of 2021. Using the same Lascar data loggers, we tracked the humidity changes over fourth dimension and compared the fluctuations to the operation of our upkeep option and to the alternative option of doing nothing at all.
The results were mixed. Using the pot was marginally better than doing nada, raising the relative humidity by about 5% when it was on the radiator. But that humidification rate was easily eclipsed by our budget choice on its lowest setting, which increased the humidification by double digits. The pot also had the downside of working but at the whims of the radiator'due south heating cycle (which, in our tester'due south case, didn't really kick on until ix or x p.m. each night).
We also tried calculation multiple pots to the radiator, every bit well as a shallow baking pan, hoping that the larger surface expanse would lead to more than evaporated water in the air, but nosotros saw no departure in performance.
Just if you're desperate and you happen to live in a building that nonetheless uses heating technology from the 1800s, a pot on the radiator volition make your air slightly less arid than a desert breeze. You lot tin reportedly reach similar results with a crockpot equally well, although the comedian John Hodgman recommends against this. We're going to take his word for it.
The wellness risks of a dirty humidifier—and how to avert them
Caring for a humidifier isn't simply about keeping the air smelling fresh—or even almost general home cleanliness. Information technology'southward besides about health. Left uncleaned, humidifiers tin can quickly become breeding grounds for numerous species of bacteria, amoebas, and fungi that trigger allergies, depression-grade fevers, and, in the worst cases, a dangerous inflammation of the lungs called hypersensitivity pneumonitis. This happens so oftentimes that it even has a nickname: humidifier lung. This condition is insidious and comes on sneakily, like a bad chest cold. It's even happened to a few Wirecutter staffers, so nosotros can adjure that it's not pleasant.
Wirecutter'south Tim Barribeau shared his firsthand experience:
We were bad humidifier parents, and definitely weren't cleaning the thing out as often as nosotros were meant to—sometimes more than a calendar week or 2 between cleaning. And fifty-fifty worse, I'one thousand pretty sure on more than one occasion water only sat inside it for days at a time. But one dry dark in winter, we turned on our adorable penguin-shaped humidifier. And the side by side forenoon, both my now-married woman-then-girlfriend and I woke up feeling like nosotros were dying. We both had incredibly tight chests, where we couldn't get in plenty air to breathe properly, accompanied by constant cough fits and tunnel vision. Nosotros assumed we'd both come down with some sort of weird chest cold and tried to ride it out for a couple of days—and kept using the humidifier the entire time. Thankfully, I'm married to a medico, and she started researching and figured out nosotros had humidifier lung. We got that thing out of the bedroom, I cleaned it, and we cleared up pretty quickly. But we both thought we had caught something pretty serious before she figured it out.
Regardless of which type of humidifier you have, you must clean it regularly to preclude funky stuff from growing in the reservoir and other parts of your machine. The EPA suggests (PDF) cleaning and disinfecting portable humidifiers every third 24-hour interval; virtually manufacturers recommend about once a calendar week. A bacteriostatic handling such as Essick Air or an antimicrobial cleaning cartridge like the fish-shaped Protec tin also help to discourage nasty things from growing. But these should still be used in conjunction with a regular cleaning.
Typically, h2o and elbow grease will do the job, but you lot may need to use distilled white vinegar every then often to remove mineral deposits (limescale). After washing the humidifier, rinse all plastic surfaces with a cleaning solution. To disinfect the tank, you lot can make a diluted bleach solution. We'd offer a specific ratio, but it's best to repeat the CDC guidelines to follow the product's instructions, since different bleach products have different concentrations. Then wipe to dry. Filling your humidifier with distilled or demineralized h2o instead of tap h2o will assistance reduce the corporeality of mineral deposits that get left behind. But you lot'll still have to clean it either way.
Do not use cleaners or bleach on the wick of an evaporative humidifier, since doing so tin can impairment the material and compromise any built-in antimicrobial treatments. Instead, soak the wick in cold water for twenty minutes and gently swish it back and along to release (oftentimes brownish, slimy) minerals that have built upward. To avoid mold growth on the filter when yous turn off your humidifier for more than a day, pull out the filter and let it dry out, or exit it in and allow the fan to run with no water until the filter is dry out. (This takes virtually an hour with the Vornado EVDC300 and causes the machine no damage.) Simply you can't clean the same wick forever. You'll need to supercede it every vi months, at a minimum.
Even though ultrasonic humidifiers do not have wicks, many of them have some kind of demineralization cartridge, felt pad, or other handling that you demand to replace every and so ofttimes.
Despite its beingness an evaporative model, the Venta LW25 has a different maintenance schedule. Considering you treat the water with an antimicrobial, anti-scale additive, Venta recommends just a elementary rinse of the tank, and rotating the wick every ten to xiv days, as well every bit a deep make clean every six months using Venta'due south cleaner.
The competition
The Carepod One is a sleek, unproblematic, and effective ultrasonic that'south also easier to clean than any other humidifier we've ever tested. On the outside, it looks kind of like if Apple tree had designed an ice bucket. Simply the tank and lid within of it are both fabricated entirely from stainless steel, and the fact that you tin sanitize it with nothing but humid water already sets it in a higher place the residuum of the pack. In fact, nosotros had planned to brand it an upgrade option—until it failed after simply a few weeks of regular use. The only plastic part of the Carepod is a wand that houses the ultrasonic diaphragm. In our tests, withal, the plastic cracked, presumably from the stress of the ultrasonic vibrations. We contacted the visitor, and it provided prompt and helpful customer service and sent usa a new model—which ended upwards having the verbal same problem. The company has since started offering a 2-twelvemonth extended warranty on the oscillation wand for anyone who has the same problem nosotros did. We've been impressed by the company's commitment to customer service, and look forward to considering any new designs they innovate.
The Honeywell HCM-350 Germ Gratuitous Cool Mist Humidifier was our top pick from 2015–21, largely because of its simplicity. The base is dishwasher-safe, at that place are no bright lights or beeping sounds to keep you lot up at night, and several Wirecutter staffers accept used it long plenty to attest to its durability. But we started hearing more and more complaints from readers who had problem cleaning the not-dishwasher-prophylactic parts or who were otherwise disappointed with this model. Its availability has as well become increasingly scarce. This is still a pretty groovy, elementary evaporative humidifier if you lot tin can notice it, just we call up almost readers volition be better served with one of our ultrasonic picks or the EVDC300.
The Honeywell HUL430 Absurd Mist Humidifier is a straightforward ultrasonic humidifier with a streamlined, stylish look. It works at least likewise as our other ultrasonic picks, too. But the cleaning process was a niggling more frustrating. The fill hole on the one.2-gallon tank is surprisingly small, which means that people with larger hands might have a harder time getting them in there to scrub. There's also one narrow cylinder/pipage inside the cylindrical tank that tin can be difficult to maneuver around, and some parts of the HUL430 are not dishwasher-safety. Also, it can be tricky to reinsert the tank once you've cleaned and refilled it; it fits in but one mode, and every bit with a USB cable, you're leap to fail on the first try every time. Finally, although we appreciated the simplicity of the single analog dial control on the HUL430, it didn't have whatever fail-safes (which the Levoit Classic 300S or LV600HH did) that could help prevent it from over-humidifying the room.
We as well used to recommend the Honeywell HEV685W, which has two tanks that together can carry iii gallons of water at a time. Afterward comparing this to the 4-gallon Vornado Evap40 in 2021, we ultimately decided not to recommend either oversized humidifier, simply considering they're and then far across the scope of our testing and what we think our readers are looking for. If you do need a humidifier to fill an extra-large space, though, either one of them would nevertheless be a good selection.
Although the Dyson–PH01 Pure Humidify + Cool is both a humidifier and an air purifier, for this guide we subjected it to our humidifier testing only. And in that regard, it did perform pretty well, with a very consistent build of humidity in the room that settled just above 60%; combined with the air-purifying feature, it left the whole room feeling nicer overall. Yet, nosotros withal think the whole thing is overkill. You can get meliorate humidification, plus an air purifier that performs ameliorate than whatsoever of the other Dyson models we've tested, for much, much less money. Even the PH01'south elaborate congenital-in UV cleaning arrangement—though impressive!—is utterly excessive, with some annoying automation that saps the value of its own convenience.
The Vornado UH100 has the same cylindrical gallon tank, safe-gasket cap, and humidification controls equally its evaporative counterpart. Information technology's just as adept at keeping the humidity level consistent, too—which is even more impressive, given the tendency of ultrasonic models to transform a room into a dank wall of fog. Nevertheless, that fan sound we didn't mind on the EVDC300 makes the UH100 stick out amidst the other ultrasonic models we tested, all of which are essentially silent. Sure, the air circulation is bang-up. Simply that placidity performance is a major appeal of ultrasonic humidifiers; otherwise, yous may as well stick with the evaporative version. (Information technology also gurgles loudly at random intervals, which doesn't aid the sound issue.) The UV100 also comes with a replaceable mineral cartridge that'south supposed to assistance reduce the fine white powder that some ultrasonics leave backside when using hard h2o. Unfortunately, the cartridge also held water in a manner that fabricated it fifty-fifty more difficult to transport both the tank and the base without splashing water all over the floor—and ourselves.
The Canopy humidifier has some of the sleekest, simplest packaging and pattern we've seen. It'south clearly designed for people who don't desire to think also much about their humidifier, and information technology has a lot of thoughtful details to aid with that, including a built-in UV low-cal, to discourage bacterial growth, and a proprietary tech, to go along the water moving and the air humidified (fifty-fifty when the unit is technically turned off). Nosotros thought this was a particularly bully stand up-out characteristic for anyone who lives in a more humid place, where they might not need to leave their humidifier running all the time. It's too the only model we've seen that's powered by a USB-C cable, and the company was considerate enough to include a cablevision with correct-angle connections so it's easier to keep it out of the manner. The whole thing is dishwasher-safe, too. Overall, information technology'south a nice, simple humidifier. Nonetheless, information technology tin can be hard to find the tiny button that controls the fan, particularly in the dark. The opening on the 2½-liter tank (half the size of what we typically recommend) is far as well modest to fit a hand within for any manual cleaning you might need to practice. And the high-pitched fan can be a lilliputian grating when it gets going. This model performed well plenty in our tests, but in that location was just no manner to justify the cost tag (normally around $150). That'south more than twice as much equally most of our other picks cost, for something that'southward louder and holds half as much h2o.
The SPT SU-9210 Digital Evaporative Humidifier had been our runner-upwardly pick for years, with a reliably serenity evaporative performance that was comparable to the Honeywell HCM-350 (plus a overnice digital display). Unfortunately, information technology's been difficult to observe since 2020. It's withal a peachy selection, if you tin find it anywhere.
Our former budget selection, the Levoit LV450CH, has been discontinued, too; it was nearly identical to our current budget pick, too from Levoit.
The Vicks V750 Warm Mist Humidifier used to be our budget pick. It notwithstanding costs near the aforementioned as our discontinued budget pick, the Levoit LV450CH. But whereas the Levoit LV450CH feels affordable, the Vicks feels cheap in every sense of the word. On the plus side, it will proceed working even later one-half the pieces snap in half during the cleaning process. On the minus side, we know from our most recent re-test that half the pieces tin can hands snap in one-half during the cleaning process. Only go this if you're really into the minty freshness of Vicks VapoRub and cannot perhaps fathom using essential oils in another (better) humidifier.
The Honeywell HCM-710 was the quietest evaporative model nosotros tested on medium—and the absolute loudest on high. Worse, it sounds like someone'southward leaning over your shoulder from behind and gurgling water in your ear. Functionally, the HCM-710 comprises piddling more than a plastic casserole dish with a fan on top. Though in that location are marker lines for the water-fill limit, it's actually easy to miss them and overfill. Honeywell was thoughtful enough to add a picayune drainage hole in the middle of the side to solve this problem. Unfortunately, it was not thoughtful plenty to consider that the water would too splash out of that hole while yous're carrying the tank back to the humidifier, making it await like you but peed your pants.
We don't recall the Aircare EA1407 Valiant Evaporative Humidifier is right for most people, although it is interesting. The makers of this large, 5-gallon "whole-business firm" humidifier claim information technology can manage upward to iv,000 foursquare anxiety of space, and the unit itself is a flooring-continuing cubic auto that weighs virtually 30 pounds and measures about two anxiety on all sides.
Earlier tests
SPT's SU-4010 Dual Mist Humidifier used to be our pick for large-space ultrasonic humidifiers. It nonetheless works fine, just the Levoit LV600HH is superior in every respect, from performance to ease of cleaning to the user interface.
The TaoTronics TT-AH002 Ultrasonic Humidifier is an Amazon best-seller. But in our tests it was a weak performer—mustering merely a 5% increase in humidity on medium. And it has a terrible design, with a modest, tippy, hard-to-clean tank.
The Honeywell HEV620B Cool Wet Tower Humidifier, an evaporative model, has a unique tower-fashion design, and it performed extremely well in our tests, humidifying the air quickly and holding the humidity steady, thanks to its accurate humidistat. We also like its behemothic, 1.vii-gallon tank, which is skillful for more than 24 hours of operation under most circumstances. The tower style does brand it visually conspicuous, however, and you tin can fill up the tall tank only nether a tub or kitchen faucet, not at nearly bathroom sinks.
The Pure Enrichment Ultrasonic Absurd-Mist Humidifier seems popular, but the authenticity of many of its reviews is questionable. And its tiny, 1½-liter tank renders information technology useless for all only the smallest spaces—maybe 125 square anxiety, a 10-by-12 room. Its (seemingly authentic) negative reviews focus on 2 other disqualifying factors: It tips over easily, and when it tips, the tank has a trend to break.
Stadler Form's Fred steam model is either a sleek and modern humidifier or an ugly conflicting saucer/mini charcoal grill. It has a 2-gallon reservoir that's practiced for running all day on loftier. The controls are simple to use, though quite minor. When y'all're assembling the machine, your hand gets pinched while installing the reservoir, and the lid is slightly difficult to align. The vent gets very hot during operation and points toward the back, and then yous tin't put the machine close to a wall. We cannot recommend information technology, fifty-fifty if you beloved its looks.
The Safety 1st Ultrasonic 360° Humidifier is budget-friendly, but its drawbacks go on it from existence a pick. It'due south express by a tiny, 0.8-gallon reservoir that will need frequent refilling. Its reservoir consists of two pieces and has a small opening (making it hard to make clean), and a long list of owner reviews complain about leaking and other bug.
The SPT SU-3600 Digital Ultrasonic Humidifier with Humidistat is compact and constructive, just our test unit had a wildly inaccurate humidistat, which read 33% for the duration of a run designed to test its ability to concord the humidity constant at 65%. And instead of property steady at that place, it pumped up the humidity to a muggy 77% and soaked the floor.
The Optimus U-31001 Cool Mist Ultrasonic Humidifier is a well-reviewed, bare-bones ultrasonic model with a uncomplicated dial control and a stiff, 2-gallons-per-day output. We establish the output rate high but extremely variable, at 1.0 to two.1 gallons per solar day (both on the loftier setting).
Dyson'southward AM10 is a uniquely shaped ultrasonic humidifier that builds on the company's before fan models. We wondered what y'all would become for spending every bit much as possible on a humidifier; the biggest difference between a basic ultrasonic model and this one, which costs much more than, is that the AM10 has a powerful fan to force the water droplets out through its oval opening. We constitute it solidly constructed and attractively designed, and, well, different—though non necessarily in a practiced way. For instance, you have to remove the oval portion before accessing the water reservoir. That's an actress step. The tank's fill hole is quite minor, about the size of a quarter, making the tank more than difficult to fill up and the knob harder to turn to seal it. Yous tin can control the unit of measurement only via the remote, and the display is quite pocket-size and dimly lit. The AM10 performed well, ranking first on ability to concur relative humidity at a set point (average 1.4% RH over the set indicate, and 0.eight% RH standard divergence) and third on humidity change (25.5% RH). Dyson definitely makes a statement with its design, but it fails to deliver value.
The Vornado Evap3 Evaporative Humidifier is a very attractive model. Information technology aced our humidity-hold examination, reaching the steadiest value among evaporative models, 3.6% over the fix point and ane.0% standard divergence. Information technology has a large, i.v-gallon tank and a loftier output of 2.7 gallons per day. It uses two wicking filters that terminal for four to 8 weeks earlier they need to exist replaced, at a price of $12. Unfortunately, it was a little loud on high, and nosotros found the fill up cap really hard to turn.
The promising Vornado Evap2 Evaporative Humidifier, the little version of the Evap3, uses a single wicking filter. It besides performed well on our humidity-hold test, coming in second amongst evaporative models. But it was besides loud (59 decibels), and inserting the reservoir was too bad-mannered. Aligning the base was also tricky for united states, as it had to come in at an angle, and we found ourselves struggling each time we refilled.
