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.
