TYPICAL INSTALLATIONS
Flow-through humidifiers are installed on either the supply plenum or return duct, based on the specific
application. Steam humidifiers are mounted directly to the ductwork or remotely to provide humidity on demand.
Controlled by a humidistat or IAQ thermostat, whole home humidifiers are designed to introduce moisture directly
into the duct’s airstream to evenly distribute humidity throughout the home.
Achieve Ideal Humidification
Homeowners don’t notice humidity levels — unless there’s too much or not enough. While air cleaners, ventilation
and UV treatment systems keep indoor air clean, proper humidification is needed to control relative humidity (RH)
levels. Too much humidity is uncomfortable and can lead to mold and mildew. Too little humidity can cause dry
skin, and damage the home’s wood furnishings.
