Model 700 Series 

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.

Evaporative Bypass Humidifiers 

Model 600/500 series

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 year.  

The Model 400 series

The Model 400 bypass humidifier uses 100 percent of the water fed to the water panel – eliminating the need for access to a drain.

Steam Humidifiers

Model 800 Series 

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 not available.
