AprilAire Humidifiers are designed to work with many different types of heating systems, delivering balanced humidity to houses of all sizes and all degrees of construction tightness.

AprilAire Humidifier Product Line:

Bypass Evaporative Humidifiers: Model 400 bypass humidifier uses 100 percent of the water fed to the water panel – eliminating the need for access to a drain. Model 500/600 bypass humidifiers offer high efficiency, simple design and minimal maintenance. Bypass humidifiers are available in multiple sizes depending on need and HVAC system. Bypass humidifiers can be installed with an automatic or manual control and require maintenance just once a year.

Fan-Powered Evaporative Humidifiers: Model 700 humidifiers are attached to the warm air up-flow supply plenum on forced air furnaces and heat pumps. The Model 700 is our most efficient evaporative humidifier. It’s easy to install and a great choice for systems with low or variable speed air handlers.

Self-Contained Evaporative Humidifier: The Model 300 Self-Contained Evaporative Humidifier is designed to help contractors install whole-home humidification in homes heated with boilers, mini-splits, radiant heat, and other ductless systems.

Steam Humidifiers: Model 800 steam humidifiers provide the highest capacity of all AprilAire Humidifiers. Our steam humidifiers are capable of delivering up to 34.6 gallons of water to the air per day, even in arid climates. An available fan pack allows steam humidifiers to be used in homes where duct work is not accessible or available.
