Do-it-yourself installation version of the HE225 whole house humidifier.
The HE220 Whole House Bypass Humidifierlets you maintain your home's most comfortable humidity level automatically. Proper humidity provides a more comfortable living environment at a lower temperature, so you can turn down your thermostat for energy savings; controlled humidity can prevent damage to hardwood floors and woodwork from over-dry air.
By-pass flow through humidification uses a by-pass off the supply or return airflow to create pressure that draws the airflow into the humidifier and through the moisturized pad. The result is an even distribution of humidity in the air throughout your home.
