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 disburses 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 through
your home.
Humidified air feels warmer and more
comfortable so you may be able to lower your
thermostat heating setpoint and save money
on your heating fuel bills. The end result is
that your humidifier gives you a comfortable
environment that is also energy efficient.
MAINTAINING YOUR
HUMIDIFIER
A regular maintenance program prolongs the
life of your humidifier and provides a more
comfortable home. The frequency of cleaning
will depend on the condition of your water.
You can use either hard or soft water in your
humidifier, but hard water mineral deposits are
more difficult to clean than soft water deposits.
