Air Care
®
models feature a two-stage air
filter which attaches to the back of the
humidifier. The Air Care
®
filters the air as
it humidifies.
The first stage of the air filter is
a high-efficiency, electrostatically-charged
filter media which traps dust, pollen and
airborne pollutants. The second stage of
the Air Care
®
filter is an activated car-
bon media which absorbs odors from
cooking, pets or tobacco smoke.
We recommend replacing the Air Care
®
filter at least once a year, more often if necessary. When the white filter media
is coated with a layer of dust and dirt, it is time to replace the Air Care
®
filter.
The certified water output of your humidifier will be reduced when using the Air
Care
®
filter
Air Care
®
filters are optional and are not required for normal operation of the
humidifier.
