How to Choose a Cool Mist Humidifier

Ultrasonic Cool Mist Humidifier

Ultrasonic Cool Mist Humidifiers function by releasing microscopic, liquid water particles into the air, where they are then absorbed into the air before they touch an object. These humidifiers use ultrasonic technology to cause the water in the tank or reservoir to vibrate so fast, that the water molecules turn into a fine mist, which is then emitted into the air via a fan. Many of these models do require maintenance with regards to filter replacements. Cool mist is often the humidifier of choice in homes with small children as cool mist is much better on their tender skin and mucous membranes.

Evaporative Cool Mist Humidifier

Evaporative Cool Mist Humidifiers work in a slightly different way than Ultrasonic ones. Here, a fan encourages the intake of outside air, then passes it over a wick which is made damp from water in the tank. The air is then released into the room, increasing its humidity. These are affordable, easy to use and maintain and can usually handle a larger living area or office.

Combination or Dual Mist Humidifiers

If you find you’d like the benefits of both warm and cool mist, then search for a humidifier that is a blending of the two. These hybrid models offer you the benefits of both at the flick of a switch. The only drawback to dual mist humidifiers is the higher price tag.


Once you’ve decided on the type of cool mist humidifier, next comes finding the right size. Remember, if you have a gigantic humidifier in a tiny room, there is a good chance that all of that extra moisture will have no place to go but into your fabrics, floors and walls, encouraging the growth of mold, mildew and dust mites. Bugs, they do love an overly moist environment. To find the perfect size, find out the square footage of your room.

Next choose from one of these 3 sizes:


Small humidifiers are portable humidifiers are the ones you put on your bed stand. These are inexpensive and used for single rooms like a nursery or bedroom. The downside to portable models is that they will require you to fill them more often than units with larger tanks. These are great units for people on the go, as they can conveniently pack into most suitcases.


For those of you who wish to add humidity to several rooms, the medium may work well for you. These are the ‘mid-sized’ humidifier, and are designed to flood a living area or single room of 650 to 1200 square feet with healthy humidity. These models are not considered portable, and usually have large tanks with over 1 gallon capacities.


The large humidifiers are meant to handle the needs of an entire home or office space. Of course, during use all doors must be kept open to reap the benefits of the humidity. Large sized humidifiers will cover an area within the range of 1700 to 2700 square feet.

Noise and Night Lights

This is an important consideration, especially if the individual has insomnia or if the humidifier is to be used in the children’s room. Some people find the LED night light feature to be bothersome, and end up placing duct tape over it so they are not disturbed. As for noise, know that the affordable, evaporative humidifiers are much noisier than the ultrasonic ones. Check the specs, if the decibel level is below 36, you should be alright.

Tank Capacity

The smaller the tank, the more often you’ll have to fill it up. The larger the tank, the longer it will operate in between filling. It may sound overly simplified, but trust me, many people find it very annoying to have to constantly go to the bathroom or kitchen sink to fill up their reservoir. Others find it equally annoying and even messy to keep jugs of water in their bedroom to fill up their little tanks.

Essential Oils

There are many individuals who claim that essential oils enhance their overall health and well-being. That being said, there are many manufacturers who are working to add an essential oil ability to their humidifiers. If you are interested in aroma therapy, please be warned that you must only place these essential oils in a humidifier that has been specifically designed to handle them, otherwise you’ll only damage your unit.

Cleaning and Maintenance

Don’t overlook this when searching for the best cool mist humidifier for your needs. Humidifiers which are not properly looked after can become a nest of bacteria, mold and mildew, and then spewing it into the air for you and your family to breath in. For instance, if you purchased a humidifier to alleviate allergy symptoms, but lately noticed that your symptoms are worse, chances are your unit needs to be cleaned. Look for models that are easy to clean.

Additional Features

Additional features are the perks of the product. The product will work fine without them, but it’s these features which often add much convenience to the design. So, when looking over the specs, check to see if you’d prefer a model with a humidstat, timer, auto shut off or an adjustable input control.


There you have it, our review for the best rated cool mist humidifiers for 2019. As you can tell, a humidifier is much more than a thing that spews moisture into the air. There is a purposeful bit of science behind their design. By choosing the correct cool mist humidifier for your needs, you will experience better nights sleep, reduced allergy and asthma symptom, and overall sense of well-being.
