Cool mist humidifier explained
We first recap what a cool mist humidifier is, just in case you have come here for the first time.
Now, cool mist humidifiers are so called because they release a steady flow of cozy room-temperature mist into the air.
This is contrary to warm mist humidifiers that disperse soothing warm steam throughout the room (they first boil the water before emitting the steam).
Types of Cool Mist Humidifier
If you’re looking at a cool mist humidifier, it’s important you know that there are three different kinds – evaporative, ultrasonic, and impeller.
Here are the key differences between the threesome members of this humidifier category:
Evaporative cool mist humidifier
These humidifiers comprise a few basic components: a fan, reservoir, and wick.
The fan usually blows warm air onto the wick via the filter.
Since the wick has absorbed water from the mounted reservoir, this triggers an evaporation process culminating in the water evaporating into your rooms as ultra-fine, cool mist.
Ultrasonic cool mist humidifier
Ultrasonic cool mist humidifiers create gentle, fine mist and pass it into the environment using ultrasonic vibration technology (not fans).
There are by far the quietest of the three types of cool mist humidifiers.
Impeller cool mist humidifier
Impeller cool mist humidifiers are a type of devices that flings water at a built-in diffuser in the process breaking the water into subtle droplets that hover in the air as moisture.
You must keep the water source scrupulously clean as bacteria and mold can easily proliferate from the contaminated water.
These are typically louder than even evaporative units.
But what exactly are the benefits of using a cool mist humidifier?
Read on to know why investing in one could be a smart move as you prepare to outmaneuver winter blues such as super dry skin, throat ailments, and more because of the air becoming moistureless.

Benefits of cool mist humidifiers and why buy
While they both moisturize effectively, cool mist humidifiers outmuscle their warm mist counterparts in four major ways:
- Kids stay safe- children (and pets) are playful and warm mist humidifiers can cause burns when they come near the steam or knock over the device (filled with hot water) by bad luck. In fact, the American academy of pediatrics recommends a cool mist humidifier for baby bedroom, nursery, or other places patronized by kids.
- Reduced energy bills- the water doesn’t need to undergo heating before being spread. Subsequently, this type of humidifiers consumes less electricity.
- Great for hard water areas- they’re not easily hurt by hard water mineral deposits and are a safer bet if you live in such a zone.
- Best for warmer climates- they bring down the ambient temperature when humidifying (think ‘cool’ mist) and are better for hotter climates.
Buying Guide (What to consider when buying cool mist humidifier)
Ok, now we’ve finished going over that, time to move on to the vital features you have to look out for when selecting the best cool mist humidifier.
You get what you pay for, right?
And features are just one of those things that can make a vast difference in humidifiers.
Specifically, a budget cool mist humidifier will have a handful of functions and settings and you may find it a bit annoying.
On the other hand, humidifiers closer to the top of the line will probably have, among other things, a humidistat, safety shut off button, super-responsive controls, etc.
Too large a humidifier for a room might create condensation which could lead to mold and bacteria to form and you should choose a unit that’s correctly sized.
Measure your room and check the indicated coverage area (square foot) when comparing to get a precisely sized device.
Beware of noisy brands
Admittedly, noises are a natural occurrence in humidifiers when it’s running, but you don’t want the types that are too noisy.
Ultrasonic cool mist humidifiers carry the day here and are outstanding for light sleepers, baby rooms, and areas where silence is a matter of life-and-death such as libraries.
Research about the maintenance
Okay. The skyline is gray as is the leftover slushy snow. You don’t want a model that makes your mood gray when maintenance time comes.
Reading the reviews will give you an idea about whether it’s easy to detach the tank for cleaning and refilling, and if the design makes installing a new filter easy-peasy.
Units with an aromatherapy option make sense if you’re passionate about the holistic healing treatment associated with aromatic essential oils.
Similarly, models with a bigger tank capacity are more convenient as they’re likely to last you the whole night.
Back to maintenance and indicators to remind you about filter change and reservoir refilling can be handy too.
Phew, that was pretty long but it’s for a good cause.
Thankfully, I saved the favorite part for many- the cool mist humidifier reviews- for last.

BONECO/Air-O-Swiss Warm or Cool Mist Ultrasonic Humidifier
The Boneco/Air-O-Swiss is an elite humidifier that accomplishes two missions with perfection: It functions as a warm mist humidifier when you need it and as a powerful cool mist humidifier when called upon.
This versatility makes it one of the very best humidifiers for rooms up to 600 sq. ft.
Part of what makes this humidifier so appealing is that it’s automated- with the integrated hygrostat; you set your desired humidity and leave it.
The mist output will adjust itself automatically as the room humidity changes and you will savor optimal humidity steadily.
The output of 3 gallons/24 hours is one of the highest for 600 sq.ft. and means it brings results faster than rivals.
The Boneco/Air-O-Swiss includes a pre-heating function to lift room temperature when it’s bitterly cold (mist exits at a pleasurable 104 °F ) and stay warm.
It’s an outstanding invention and comes with water maintenance accessories like a demineralization cartridge (to control scale/mineral residues) and hydro cell (to keep it fresh).
Finally, the multifunction display is a pleasure as are the practical refill and cleaning reminders.
- Low noise especially in night-time mode.
- Functional timer.
- High quality.
TaoTronics Cool Mist Humidifier, 4L Ultrasonic Humidifiers
TaoTronics cool mist humidifier’s automatic humidity levels monitoring system keeps your indoor humidity at a magical level all the time.
We were especially impressed with its 12-30 hour running time on full tank (4L capacity) and its incredible 38 dB noise level (lowest limit of ambient sound in urban areas).
The great steam output from the reliable TaoTronics cool mist humidifier is perfect for soothing irritation of the nose, throat, skin, lips, eyes, as well as issues like rashes, severe nasal congestion, and more.
We also found the LED display quite detailed, the digital controls easy to maneuver, and the three mist levels more aggressive.
All these help it earn the top spot for units designed for spaces 107-322 sq. ft. big.
We additionally like that it lets you choose between turning on the soothing nightlight or sleep mode (to turn off its LED screen) and sleep like a log.
Overall, this is the king for condos, baby room, and other environments where disturbances are unwelcome.
- Safe- goes off automatically on low water.
- Plentiful coverage (360° nozzle).
- Easy tank cleaning/refilling.
- No aromatherapy provision.
Honeywell HCM350W Germ Free Cool Mist Humidifier
Good luck getting a humidifier that brings healthier moisture than what you get from this HCM350W unit from Honeywell.
The scientifically proven ultra-violet light technology kills about 99.9% of harmful organisms in the equipment’s water and your room will be filled with germ-free moisture.
Another winning device (for rooms up to 360 sq. ft.), this uses Honeywell’s patented QuietCare technology and is nearly 30% quieter than the rest.
It has just 3 settings (high, low, medium) -rather than tens of controls to learn- and adjusting output and sound levels is quick and easy.
The reservoir design is another attraction- it’s easy to fill and features a superb recessed tank handle so it won’t slip out of hand when wet.
I should add that the 1.1 gallon tank runs for up to 24 hours making it another option when you’re facing dry winter nights.
Plus, it’s a lasting unit and comes with a 3-year limited warranty.
- Relaxing, invisible moisture.

Pure Guardian H920BL Ultrasonic Cool Mist Humidifier
Thanks to its slim design, the compact H920 cool mist humidifier is the perfect choice for tabletops/ bedside nightstands.
The company has added silver clean protection to the tank so mold and mildew won’t grow like it often happens with traditional humidifiers.
It doesn’t have quite the oomph (packs two speed mist settings only) of larger competitors, but it still puts out decent vapor as long as your space isn’t more than 210 sq. ft.
In fact, it provides a slot (on the top) that lets you rotate the nozzle to direct the mist where you need it most.
We love so many things about it including the idea of implementing an LED night light (optional) which is great for those who suffer problematic sleep.
Like most, the low water warning alerts you when a refill is needed.
Plus, it shuts off automatically for safety when empty.
The 0.8L tank is reasonable and can runs for about 10 hours (on low setting).
- Whisper quiet.
- 3 year warranty.
- Space saving design.
- Small tank capacity.

You can easily tell if it’s running- the indicator light turns blue.
Likewise, you will know when it runs out of water- this time the indicator light turns red.
Besides, it will conveniently switch off the moment it’s out of water.
