Cooler temperatures bring cozy sweaters, crunchy leaves, everything with pumpkin spice—and for many of us, dry skin and chapped lips. IfLotionand lip balm are not enough, an evaporative humidifier could be the solution. By blowing moisture into the room, a humidifier can also provide relief from chronic congestion, frequent nosebleeds and sore throats, allergies, and dry eyes.

After spending several hours researching the product category, discussing it with medical and air quality experts, and spending weeks testing four of the most popular evaporative humidifiers on the market, we've narrowed our favorites down to two products: the bedroom canopy and the Honeywell HCM 350 for larger rooms. Both products received high marks for ease of use and effectiveness, while the Canopy received additional credit for looks and safety.

Here's the TL;DR on how the best evaporative humidifiers stack up:

  1. canopy(Best for smaller spaces and bedrooms)
  2. Honeywell Cool Moisture Humidifier HCM 350-Serie(Best for larger rooms)
  3. Honeywell Cool Moisture Humidifier HEV320 Quiet comfort

I fell in love with the canopy a little before I even finished unpacking it. For a humidifier, it's surprisingly easy on the eyes. It comes with up to three vials of essential oils that made my office smell like an upscale spa, a puck - a small, flat disk onto which some of the included fragrance oil can be dripped - and was beyond easy to use. It also comes with a cylindrical filter that turns brown when it's time to change it and order new ones. It only has one intensity setting, which keeps things simple. Even better, according to my hygrometer, my office stayed at 40 to 50 percent humidity as long as the door stayed closed. (I assume the level stayed within acceptable limits as air was leaking through the doorway, windows, and ducts.) As with all humidifiers I've tested, I didn't notice any differences in my skin or general health. Still, it was reassuring to know the room had good humidity, especially considering I live in a high desert climate.

Even if the Canopy wasn't aesthetically pleasing with its compact size, clean lines, and pastel-colored ventilation, its intelligent design would have set it apart from the competition. According to its product website, it features a technology called Smart Persistent Airflow (SPA)™ that runs automatically until the device is completely dry inside. This is to prevent mold from forming inside the tank. I also loved that it has an indicator light that lets you know when to change the filter.

The canopy is also ridiculously easy to set up, use, take apart, and clean. Like most products I've tested, the key parts you need to clean - the tray, tank, and lid - are dishwasher safe. Although I could have figured it out without the guide, the elegant quick start guide explains everything in a few succinct bullet points.

Yes, the Canopy is a bit more expensive than its competition (okay, a lot more expensive), but it's also quieter, easier to use and, dare I say, a lot cuter.

Best for larger spaces

  • Not the prettiest
The best evaporative humidifiers of 2023 (4)

The Honeywell Cool Moisture 350 Series will not earn style points. Still, it humidified my 210-square-foot, high-ceilinged master bedroom effectively without being too noisy. I also had no headaches setting it up, operating it, disassembling it, or cleaning it.

The humidifier has a quick start guide printed right on the packaging flap, which I appreciated, but really didn't need to. Setup was intuitive and easy to use, taking less than five minutes from start to finish. Once the room reached about 40% humidity, it would fluctuate between 40 and 45% as long as the hallway and bathroom doors were closed.

Three fan settings mean you have control over humidity and sound without having to deal with the overwhelm that can come with too many choices. The highest setting was a bit noisy for me when trying to sleep, but the medium setting was fine and kept the room at or just over 40% humidity.

As for care and maintenance, I appreciate that many of its parts are dishwasher safe. Also, the owner's manual detailed how to store it during the off-season, which gave me a measure of reassurance about protecting against potential mold growth.

Are evaporative humidifiers worth it?

Possible Benefits

In general, adding some moisture to a dry environment is good for your skin and overall health. But it's debatable whether an evaporative humidifier is the best way to do it.


"Using a humidifier every night can help keep the air more moist, and in turn, your skin needs to absorb more moisture as well," she saysTracy Evans,MD, MPH, board-certified dermatologist and medical director of Pacific Skin and Cosmetic Dermatology. This is especially important for those who live in dry climates, especially in winter when the heating is turned on and the air gets even drier, she adds.

For some, humidifiers can provide relief from serious skin conditions. SomeResearchJournal of the European Academy of Dermatology and Venereology"The influence of ambient humidity and temperature on skin barrier function and dermatitis"Show source codeshows that low humidity and cooler weather may increase the prevalence and risk of flare-ups in people with atopic dermatitis. Humidifiers can also be helpful for people who havedermatitis of the handand people using topical and oral retinoids, which can causedryness and irritationHarvard Health Publishing"Do Retinoids Really Reduce Wrinkles?"Show source codeon skin and lips. However, there is alsoDataJournal of the European Academy of Dermatology and Venereology"Room humidity and the skin: Influence of humidity in healthy and diseased states"Show source codesuggesting that drier environments might actually help people with skin conditions like eczema.

It's still unclear whether humidifiers (of any kind) can help with other chronic conditions like congestion, coughing, dry eyes, and frequent nosebleeds. SomeResearchCanadian Pharmaceutical Journal“Humidifiers and Vaporizers”Show source codesuggests that a humidifier can help you breathe easier and reduce the need for medication when you're stuffy.


LikeCanadian studyAmerican Journal of Epidemiology"Childhood Asthma and Indoor Environmental Risk Factors"Show source codefound that humidifier use was a risk factor for developing childhood asthma. And in South Korea, there was a well-established link between inhaling humidifier sanitizer and lung damage. (These disinfectants are no longer available.)

Whatever you do, keep your humidifier clean and consider filling it with distilled water. "Finding an easy-to-clean humidifier is important, as it should be cleaned once a week," says Evans. Concentrate on keeping the tank and base clean. If the filter or wick becomes crusted or discolored, do not attempt to scrub it - it must be replaced. You can clean other parts with a mixture of water and white vinegar or bleach. Some can also be put in the dishwasher. “Tap water (as opposed to distilled water) contains contaminants that can build up on your humidifier. They can also harbor mold or fungus inside,” she explains.

Keeping the environment out of it is also importanttoDamp, as this can cause bacteria, fungi, and mold to grow on the surfaces of your home. For optimal health, indoor humidity should be between 40% and 60%, he saysMichael Ham, an air quality specialist in Westchester, NY.

The problem with evaporative coolers is that they're not the smartest of home appliances. They keep running until they run out of water or you turn them off, regardless of humidity. This can potentially lead to excess moisture and all the health problems that come with it, says Ham. Unless you buy ahygrometer- a small, battery-powered device that gives real-time humidity readings - and being vigilant if you check it, you'll be groping in the dark about humidity levels. And according to Ham, the risks of unknowingly hitting 60%+ humidity levels just aren't worth it. (Ness ordered mea hygrometerfor use with every product I've tested.)

What is the difference between evaporative and ultrasonic humidifiers?

When shopping for a humidifier, the first thing you need to decide is whether you want an evaporative humidifier or an ultrasonic humidifier.

Evaporative humidifiers release moisture into the air by using a fan that forces air through a moistened absorbent substance such as a belt, wick, or filter. Some evaporative humidifiers heat the water into steam and are known as "warm mist" or "steam" humidifiers, while others (including all the products we tested) never heat the water and are known as "cool mist" humidifiers. In either case, the water is turned into vapor before leaving the humidifier, which is why the mist they emit is invisible.

Ultrasonic humidifiers, on the other hand, release water droplets directly into the air. These droplets only become fumesafterYou have exited the humidifier. Ultrasonic humidifiers use ultrasonic vibrations to create a cool mist. Like evaporative humidifiers, they contain a container that you fill with water. They also contain an element that vibrates at a very high frequency (beyond what humans can hear). The vibrations throw microscopic water droplets into the air, where they quickly evaporate, increasing humidity.

Each product type has its own advantages and disadvantages. Although ultrasonic humidifiers are more effective at moving moisture into the air, this can also be a major disadvantage. Excess moisture seriously increases the risk of creating an environment where moisture and mold can proliferate. At least that's what happeneda known caseAmerican Academy of Pediatrics“Lung Injury from Inhalation Associated with “White Dust” Humidifier”Show source codeof an infant suffering severe lung damage from inhaling mineral dust emitted from an ultrasonic humidifier.

Ultrasonic humidifiers are generally more compact and quieter than evaporative humidifiers. However, if the droplets don't have time to evaporate before landing on a surface, or if the air is already humid, evaporative humidifiers can end up creating a puddle of water on the ground.

Both product categories can increase your risk of inhaling harmful particles such as bacteria and mold.ResearchCivil engineering journal"The Effects of the Use of Portable Humidifiers on the Distribution of Airborne Particulates Indoors"Show source codeevaporative humidifiers have been shown to be far safer.

Meet your guinea pig

I have personally tested all the products you read about. I'm a health and fitness junkie and a freelance health journalist who's written on everything from pull-ups to piriformis syndrome. As a writer for media outlets including The Washington Post, The Guardian, Time, Runner's World, SELF, Outside, AARP, and WebMD, as well as interviews I've hosted on my Real Fit podcast, I've spoken to hundreds of experts, including Ultra - Endurance athletes, sports physicians, sports psychologists and Olympians.

Before becoming a freelance health and fitness writer, I was an occupational therapist. For more than a decade I have worked in a variety of healthcare settings (mainly hospitals) helping people with chronic and acute conditions (think stroke, joint replacements and head injuries) function as best they can. That meant developing treatments that helped my patients become stronger, more coordinated, and more confident. I have also educated patients and their families on how to keep their homes as safe as possible.

In addition to my healthcare experience, I am certified by the American Council on ExercisePersonal trainerand a certified intuitive eating consultant and the host ofreally fit, a women's health and fitness podcast. Although my first love is endurance sports — I've run six marathons and two Ironmans — I've also dabbled in CrossFit and weightlifting. As a Group Fitness Instructor, I teach indoor cycling.

And as a mother to a child who spent the early years of his life with severe allergy-related nasal congestion and eczemaAndHaving lived with eczema myself for many years, I have had personal experience with humidifiers.

Our testing process

The testing process began long before I even laid eyes on any of the products. I started researching the evaporative humidifier market to find out how they differ from ultrasonic humidifiers, how they can help people, and which products are the most popular. I spent about three hours combing the internet to see what I could find out.

(Video) ✅ Top 5:🏆 BEST Evaporative Humidifiers In 2022 [ Best Humidifier For Large Room ]

Armed with answers to my questions, I made a list of potential products for testing and ran it through The Nessie's team. We then refined my original list to include the four evaporative humidifiers I ended up putting to the test, and The Nessie bought them for me to try.

The testing process was straightforward. I used each humidifier every day for a week, refilled each as needed, and cleaned each at least once. I used the two smaller humidifiers (the Canopy and the Honeywell HEV320) in my 110 square foot office, while I worked from about 9am to 5pm each weekday, I used the two larger humidifiers (the Sharkzilla and the Honeywell HCM 350) used. in my bedroom which is 210 square meters. Given my home's layout (which is fairly open plan) and where I spend most of my time (mainly working or sleeping, which sounds a lot sadder, I didn't have a lot of options as to where to put my humidifiers, which is.)

As I used each humidifier, I thought about how easy it was to set up, use, and clean, how loud it was, how many settings it had, and if/how much it felt like improving my health or air quality At home. Most importantly, I used a hygrometer to check the humidity regularly. Without the hygrometer, I would have had no idea how well any of the products were working: I couldn't see any benefits for my skin or my health.

The buying guide for evaporative humidifiers

The best evaporative humidifiers of 2023 (7)

Who Should Buy Evaporative Humidifiers?

Evaporative humidifiers are for anyone with dry skin, eczema, psoriasis, chapped lips, asthma, chronic constipation, frequent nosebleeds, frequent sore throats, allergies, and/or dry or irritated eyes looking for a non-medicated at-home remedy for their symptoms.

While research shows that humidifiers can help with at least some of these problems, there's also a chance that a humidifier can make the situation worse, especially if the environment gets too humid (which can encourage mold and fungus growth) or if the humidifier is too wet ejects bacteria or other particles. Anyone who buys a humidifier must commit to cleaning it regularly and should strongly consider only filling it with distilled or purified water.

What features are most important when buying evaporative humidifiers?

  • Ergonomics/Ease of Use
    How easy is it to fill, operate, disassemble, clean and reassemble? Are the buttons clearly labeled and easy to understand? Is it easy to turn on and off and adjust settings?
  • moisture regulation
    How long will it run if left alone? Will it detect a certain level of humidity in the air and turn off at that point? Should users be concerned about the possibility of introducing too much moisture into the air? (As far as I could tell, no products in this category regulate humidity. The only way to make sure your humidity level is safe is to monitor it with a hygrometer.)
  • adjustability
    How many settings does the product have? Can you adjust fan speed, runtime, or both?
  • noise level
    how loud is it Is the noise a pleasant white noise, or is it interfering with your ability to work, concentrate, relax, or sleep?
  • effectiveness
    Does it relieve your symptoms? Most importantly, can it get the room up to 40 percent humidity (and no higher than 60 percent) according to your hygrometer reading?

  • Intuitive setup, operation and maintenance


  • Has not increased the moisture content to a minimum
  • Strong smell

The Honeywell HEV320 wins points for ease of use and price, but I just can't recommend a product that doesn't bring a room to the minimum recommended humidity level. In addition, it gave off a very unpleasant smell when it was first used. (Washing helped, but still.)

Since I didn't notice any improvement in health, general well-being, or skin from using either humidifier, the humidity readings from the hygrometer served as my only metric for effectiveness. Unfortunately, this product did not pass this test. I even tried it in two different rooms just to give it a good shake, but it never reached 40% humidity — not even overnight with the door closed for hours.

  • Cooles Design


  • Filling and emptying can be cumbersome
  • Operation not intuitive
  • Did not effectively bring humidity to recommended minimum levels
  • Lots of leakage

Initially, I liked the Sharkzilla's unique design. Unlike the other products that have curves and smooth edges, the Sharkzilla was shaped like a cube with sharp edges. While the design was beautiful to look at, it performed poorly from start to finish.

Also, unlike the other products that all have a tank that you can take straight to the sink and fill under the tap, the Sharkzilla's body and tank are one unit. That means it fits awkwardly under the faucet at best. As it turned out, this was on purpose; As I carried the device from the sink to my bedroom, water sloshed around and eventually ran out the sides, which are vented to help vent the mist. After reading the instructions (which seem to have been run through an online translator a number of times and were difficult to understand) it became clear that I should have poured water from a glass or jug, an extra step not required for filling was one of the other products I tested.

The fun really started when I turned on the Sharkzilla. The buttons have icons that were both difficult for me to recognize and interpret. Even after reading the manual multiple times and trying to follow the instruction chart, I was confused.

When I tried setting it up for night time use with the lights dimmed, things got even worse. It was even harder to see the buttons without a bright overhead light, and every time I pressed the wrong button the machine would emit an annoying beep. It also had a bright light which was annoying when sleeping. Although this light was dimmable like the other buttons, adjusting it took some trial and error.

Once I got it working, I found that... it didn't really work. Despite having it on what I thought was the highest setting (at least during the day; at night the highest setting was too loud), it never reached 40 percent humidity in the room, which was normally around 30 percent humidity.

Draining was pretty easy as long as I poured the water straight into the sink. When I tried to water my plants with the leftover water, it spilled out the vented sides and made a mess. I had no issues cleaning it, but it was no easier to clean than any other product I've tested.
