GETTING TO KNOW YOUR COOL
MOISTURE EVAPORATIVE HUMIDIFIER
Invisible moisture
• Evaporative humidification means you
will NOT see the moisture output.
• With evaporative humidification, a
fan pulls dry air from the room through the saturated wicking filter. Moisture from
the wicking filter evaporates and is pushed into the room with the help of the fan.
• Evaporative humidification adjusts moisture output to the amount of moisture the air can hold.
The drier (less humid) the air in the room, the more moisture the humidifier will add to the air. An
evaporative humidifier cannot add more moisture to the room than the air can hold. The amount of
moisture the air can hold depends on many factors including relative humidity level, temperature and
size of room.
Filter
• A wicking filter is required for this
unit to operate (one included)
• The wicking filter will help to capture minerals
from your water and will help to prevent white
dust (mineral deposits from hard water)
• If you have hard water, you will need
to replace your filter more frequently
• See "Caring for your Filter" section for tips on
prolonging the life of your wicking filter
