Humidifier Selection Tool

Since there are so many different models, sizes and brands we decided to create a spread sheet listing the most popular residential and light commercial models we offer. They are sorted by the maximum capacity they will handle. Once you narrow down your search by capacity then determine if you need it attached to your ductwork or if you are placing it exposed in the room (Self Contained) like a warehouse application (most residential applications need it attached to the supply OR return ductwork). Click on the model number you want additional information on and the detail page for that product will come up. If you have any questions about narrowing the selection down further feel free to give us a call.

Maximum capacity is based upon a very tight envelope that leaks at a rate of .5 air changes per hour. If your home is under 5 years old you likely have a tight envelope. If you have an older home 5 to 40 years old, multiply the capacity by .5. If you have a home older than 40 years, multiply the capacity by .25.
