We offer two types of cool mist humidifiers – evaporative and ultrasonic. Our ultrasonic cool mist humidifiers disperse a micro-fine cool mist with virtually silent operation. An evaporative humidifier passes water over a filter wick and disperses a comfortable mist that cools down a room and makes it easier to breathe. The ultrasonic humidifiers offer the advantage of being virtually silent while the evaporative ones are better for hard water areas as well as larger spaces. We offer a variety of bedroom, multi-room and small portable cool mist humidifiers. Read our expert and customer reviews for each cool mist humidifier by clicking on the models below.
If you are interested in other types of humidifiers we have a large selection.
Ultrasonic Cool Mist: We offer a variety of ultrasonic cool mist humidifiers that can disperse a micro-fine cool mist into the air and do not have a heating function option for a warm mist option. For the ultrasonic cool mist only we recommend the Air-O-Swiss 7145 and Stadler Form Hydra. Ultrasonic humidifiers to our mind are the humidifier technology of choice since they are quiet, and consumers love them as they are lightweight and their features are user friendly. Less expensive brands do not tackle the problem often associated with humidifiers which is white dust dispersion, humidity control and bacteria breeding in standing tanks of water. However the newer and better ultrasonic humidifiers such as those mentioned above have all solved that problem.
Evaporative Cool Mist: With our evaporative cool mist humidifiers, humidity is produced by a fan that draws the air in from the room and blows it over or through a moistened wick in water. Some of this water evaporates and this water vapor is added to the air which increases its humidity. This air is then blown back into the room to increase the humidity in the room. This air is not wet; it just has more humidity in it. Since heat is removed from the air when evaporation occurs, the air is cooled as a result, and presto, the air coming out will be cooler than when it went in. Of course, this can be a disadvantage to someone who likes to keep their home warm and the mist can have a slightly clammy feeling to it.
Air Washers: The beauty of an Air Washer Humidifier is that in addition to being a humidifier, it traps pet hair, large dust and pollen particles in its base unit so has some added benefit of air cleaning. We have found that these kinds of humidifiers can remove allergen particles as small as 1 to 1 ½ microns in size which will improve the air one breathes. However, if one is looking to clean the air thoroughly of all allergens, a stand alone dedicated air cleaner is recommended that will eliminate the sub micron allergens that can affect some people’s health. They are a form of evaporative cool mist humidifier, except the water is evaporated from a series of rotating plastic discs instead of filter wicks.
