How to size a Humidifier?

How do I size and find the right Humidifier?

Humidifier sizing is first a matter of comfort, how humid are you looking to make it? It is best to shoot for humidity around 30 – 40% because anything over 50% encourages the growth of mold and other allergens like dust-mites.

There are three major sizes of humidifiers and they each have a different gallon dispersion rating as well as square footage usually covered.  It is best to think about how much square footage you are aiming to cover and how many rooms.

Small Portable/Tabletop humidifiers

White PowerPure 4000 Cool Mist Ultrasonic Humidifier
PowerPure 4000 by Aerus

Coverage: 15 – 900 square feet, so it really depends on which unit you choose. Usually the least expensive and best for a single room like a bedroom. These tabletop humidifiers require refilling and are available in both warm and cool mist humidifier choices.  We offer both Cool Mist humidifiers and also combination Warm & Cool Mist room humidifiers. Boneco by Air-O-Swiss humidifiers, Stadler Form humidifiers and PowerPure humidifiers are all top rated table top humidifiers that are quiet and available in several sizes depending on the size of room you need to humidify.

Whole Home or Console Humidifiers

Coverage: 1,000 – 2,700 square feet, have larger tanks and stand on the floor. Because they are larger they humidify multiple rooms but remember those larger tanks require some muscle to fill. They are all evaporative cool mist and are relatively noisy although do a good job for humidifying larger spaces.
