Best Cool Mist Humidifier Reviews – (Recommended Picks)

best cool mist humidifier reviews 2019

1. Diverso Devices HD-1355A Ultrasonic Cool Mist Humidifier Review

The HD-1355A from Diverso Devices is our pick for the best cool mist humidifier of 2019 – 2018.

This machine has a lot going for it. It has even been praised at the best cool mist humidifier for a baby by leading experts and the cool mist humidifier reviews posted online by consumers are glowing.

What We Liked: This is an attractive cool mist humidifier. The LED display is accurate and easy to read. The touch controls are fine, but it also includes a remote so that you can use it from across the room. The tank holds 1.63 gallons, which allows the humidifier to run for up to 18, 31 and 62 hours unattended on the high, medium and low setting, respectively. It’s also very quiet and features a soft night light.

What We Disliked: The manufacturer recommends only using distilled or filtered water. There isn’t a built-in filtration system, and for some reason, no battery is included with the remote.

2. Levoit B01MYGNGKK Hybrid Ultrasonic Cool Mist Humidifier Review

Our team was quite divided on whether the LEVOIT or DIVERSO model should be number #1 cool mist humidifier 2019 – 2018.

This Levoit model is generally about 50 percent more expensive, but it’s also an ultrasonic humidifier that can provide warm mist too. We’ll focus on the cool mist here. Note that the model we reviewed is the B01MYGNGKK. It also has a larger and pricier big brother that’s quite good: the LV550HH.

What We Liked: This model is arguably the best cool mist humidifier for large rooms. It is quiet enough for bedroom use. The LED display is easy to read and shows you the current humidity. It also features a convenient side draw that accommodates drops of essential oils to be dispersed throughout a room.

What We Disliked: Not much. This model isn’t as easy to clean as we’d like. If you have hard water, it can be quite difficult to clean and require cleaning on an almost weekly basis in our experience.

3. Ultrasonic Cool Mist Humidifier by Everlasting Comfort Review

Which is the best cool mist humidifier on the market? Many leading reviewers choose the Everlasting Comfort humidifier as their top option. We get it. There’s a lot to love.

What We LikedDuring this cool mist humidifier review, we were impressed by the amount of mist this model could put out and how long it lasts. It’s in the discussion for the best cool mist humidifier for large rooms and can even last for up to 50 hours without a refill. It also has an automatic shut-off feature, and an essential oil tray lets you enjoy the benefits of aromatherapy as well.

What We Disliked: Our only real gripe with this humidifier is how inconvenient it is to fill. Many online user reviews agree, and a bit of a redesign could have this cool mist humidifier vying for our top spot. In addition, if you have hard water, we’d recommend a water filter for at lease one of your faucets.

4. Cool Mist Humidifier Diffuser by LUOYIMAN Review

This cool mist vaporizer from LUOYIMAN is our pick as the best cool mist humidifier for a small room.

It is a bit on the small side, so it’s not ideal for larger areas, but it is ideal as a personal humidifier. It also has an attractive look and wouldn’t look out of place if used on your desk at work.

What We LikedThis cool mist humidifier is easy to fill and clean. We liked that you can set it for a number of hours or just set it to run and have it automatically shut off when the water runs out. It is also extremely quiet, which makes it ideal for bedroom use. It also won’t bother other people if used in a community space.

What We Disliked: We could do without the colored LED lights. You can turn them off. With the lights on, it detracts from the wood aesthetic and looks a little to dorm room-ish for our liking.

5. Ultrasonic Cool Mist Humidifier by PurSteam Review

What We LikedThis humidifier by PurSteam is in the discussion for the best cool mist humidifier for a small room, and the pricing is fantastic too. It features a 2.2-liter tank, which allows for about 17 hours of continuous operation. A low water indicator alerts you when refilling is necessary. This humidifier has an automatic shut-off feature

It has a night light too, which is a nice touch, and you can disable it if you find it bothersome when trying to sleep. The light button is right next to the variable knob control, which is convenient for adjusting it at night even if you don’t use the light all the time. The noise output is excellent too.

What We Disliked: We expected better coverage. The marketing recommends up to medium-sized rooms, but even 330 square feet, which is the average size of the modern living room, seemed to be a bit too much area for this product. We’d recommend 300 square feet or less for this cool mist humidifier.

6. Ultrasonic Cool Mist Humidifier and Vaporizer by Homasy Review

When asked which is the best cool mist humidifier on the market to give as a gift, this product by Homasy is our recommendation due to the price, visual design and overall feature set.

What We Liked: This is the best cool mist humidifier ultrasonic steam vaporizer available! Say that three times fast, but this really is a fantastic machine at a great price. It is easy to fill, attractive and modern enough for the living room and quiet enough for bedroom use. It operates for more than 10 hours without needing a refill. It offers three mist modes as well as a night mode to avoid any disturbances.

What We DislikedThe egg-shaped design—that we absolutely love—doesn’t lend itself well to easy cleaning. You can take it apart, which helps, but a thorough clean is more of a hassle than we’d like.

7. Cool Mist Humidifier by TaoTronics Review

What We Liked: What puts this product among the best cool mist humidifiers of 2019 is the overall feature set packed into a compact design. It’s very easy to carry this unit to the sink for refilling and then back into your nursery or bedroom. It operates for up to 30 hours—or 12 hours on high—on one full 4-liter tank. It features an integrated humidistat, and you can set the precise humidity level that you want.

The TaoTronics cool mist humidifier does have an integrated filter for water hardness, which you can clean with vinegar. It helps but isn’t a solution if you have very hard water. It also includes an optional filter to combat microorganisms and bad odors. This requires changing about two to three times a year.

What We Disliked: Coverage is a bit lacking in larger rooms. The manufacturer lists the product for use up to 322 square feet, but in our experience, that may be an optimistic estimation.

8. Germ-Free Cool Mist Humidifier by Honeywell Review

The Honeywell HCM350W is among the best-selling cool mist diffusers on the market!

What We Liked: This model has a 1-gallon tank, which allows for 24 hours of continuous operation on the low setting. Germs are combatted by passing water under a UV light bulb before it goes through the filter. This isn’t a cure-all for dirty water, but it works nicely to combat odors.

The HCM350W cool mist humidifier is a bit larger than you may expect from images online. It handles large rooms quite well, but it’s ideal for bedrooms and nurseries too. We like the ease at which the tank can be removed, carried via a handle to the sink, refilled and then replaced.

What We Disliked: The biggest issue with the HCM350W is the cost of the filter coupled with the frequency at which Honeywell recommends you change it—about every 45 days or so.

9. Classic Ultrasonic Warm and Cool Mist Humidifier by Crane USA Review

What We Liked: This Crane USA product is another excellent choice as the best cool mist humidifier ultrasonic steam vaporizer for 2018. It features a removable 1-gallon tank that easily fits under most sinks and can provide 12 to 24 hours of continuous operation depending on how high you have it set. It also features an aromatherapy pad that you can use for essential oils or medications. It’s also very nice to have the option for warm mist when the weather—or how you feel—calls for it.

What We Disliked: This ultrasonic humidifier doesn’t handle water hardness well at all. There is no filter option, and using hard water will make this product quite difficult to clean. Filtered or distilled water is preferable.

10. Ultrasonic Cool Mist Humidifier by VicTsing Review

The last item on our best cool mist humidifier 2019 – 2018 list is the VicTsing humidifier!

What We Liked: What puts the VicTsing in the discussion for best cool mist humidifier is the build quality at this price point. This isn’t the most sophisticated humidifier on our comparison table, but it’s built to last and performs very well. It’s quiet enough to use in the bedroom, indicates low water with an LED light and can operate continuously up to 24 hours on a full tank. It also comes with an antibacterial component, which must be replaced over time but is optional.

What We Disliked: The biggest knock against this cool mist humidifier is that it’s not particularly well designed for cleaning. Some aspects are inaccessible, so soaking vinegar in it is the only option. Another issue is the red light that comes on when water is low. If you forget to fill your humidifier and the light comes on at night, it can light up a dark room.

How We Tested the Best Cool Mist Humidifiers

In order to determine the best humidifier 2019 – 2018, we tested many different products across many different brands. Our team tested these subjectively—as in how they made us feel—and objectively—as in how accurate integrated hygrostats were and how efficiently these machines operated in general.

It’s worth mentioning that we didn’t limit ourselves to cool-mist-only humidifiers. We also tested ultrasonic models that could do both. When testing these, we focused on the warm mist aspect of the product but also made sure that any other modes at least achieved adequate performance.

Who Should Use Cool Mist Humidifiers?

Everyone can benefit from using a cool mist humidifier. The proper relative humidity helps you to feel comfortable at the lowest possible temperature. It also makes it easier to breathe, hydrates the skin and can diminish and even alleviate symptoms related to allergies and various breathing conditions.

If you’re considering our humidifier reviews in order to determine the best cool mist humidifier for a baby or to use around children, then cool mist is where it’s at. Warm mist does present a burn risk and is therefore not advised for use in nurseries or around children in general. [1]

Is cool mist or warm mist humidifier better? Well, it’s a matter of climate too. Warm mist works more effectively in cooler climates and vice versa. That doesn’t mean that you can’t use cool mist when it’s cool. You can, but if you’re striving for optimal efficiency, then you should opt for cool mist when it’s warm outside.

What to Consider When Choosing the Top Cool Mist Humidifier

Three factors are paramount when it comes to the best cool mist humidifiers 2019-18:

  • Room size
  • Room type
  • Maintenance requirements

Determine your budget up front. If you need multiple humidifiers for multiple rooms and purposes, plan that as well. Ask yourself: is cool mist or warm mist better? It depends.

If you’re still here and have a budget in mind, it’s time to consider the room requirements. Almost every cold mist humidifier will be rated for square footage based on the amount of mist its able to deliver. As for room type, consider usage. For bedroom use at night, noises and undimmable LED lights are probably a no-no, and for a living room, you may want something that actually serves as a bit of decor.

Finally, you need to think ahead about maintenance. There may be replaceable filters for water hardness, microbial contaminants and so forth. Additionally, it matters how difficult a cold mist humidifier is to fill and clean because you’ll be completing these tasks on a regular basis for as long as you use it.

Can a Cool Mist Humidifier Make You Sick?

There’s nothing about high or low humidity that can make you sick. High humidity in particular can certainly make you feel less comfortable, but it cannot affect your health. [2]

Nevertheless, there are some concerns to note. The first involves overuse of a humidifier. A cold air humidifier can add a lot of moisture to the air. Left unchecked, that could create an ideal environment for mold, which could affect your health or at least diminish indoor air quality. [3]

The biggest risk is air contamination. Even the best humidifier of 2019 – 2018 can foul your air if it is left uncleaned. This is why we recommend humidifiers that are easy to clean and feature an antimicrobial agent. You must also clean the unit and change out any unused water on a regular basis. [4]

Final Thoughts: Cool Mist vs Warm Mist or Ultrasonic Humidifier?

Well, there you have it. A lot of research went into these top 10 best cool mist humidifier reviews, and we hope that you find this information useful. Let us leave you with one final piece of advice. While we prefer cool mist humidifier to warm mist for a variety of reasons, we’re particularly partial to ultrasonic humidifiers that we can run cool most of the time but switch to warm mist whenever the weather or our comfort calls for it.
