WELCOME
Congratulations on your purchase of a Honeywell whole-house humidifier. Proper use
of a Honeywell humidifier has numerous benefits related to your family’s health and
comfort, as well as helping to safeguard and protect your home.
How Your Humidifier Works
Your Honeywell humidifier uses the principle that vapor (evaporated water) is created
when warm air blows over a water-soaked area. As the vapor circulates, the relative
humidity rises.
Your humidity control monitors the relative humidity and activates the humidifier
accordingly. The humidifier has a water supply that dispenses water evenly over a
humidifier pad. The warm dry air from the furnace passes over the humidifier pad and
picks up the moist air to circulate it throughout your home.
Humidified air feels warmer and more comfortable so you may be able to lower your
thermostat heating setpoint, which saves money on your heating fuel bills. The end result
is that your humidifier gives you a comfortable environment that is also energy efficient.
Model Specific Features
The HE280 humidifier has water savings technology built in that could save up to 30%
versus leading brands. This translates to up to 20 gallons of water saved per day!
