Air Care® Filter

MODEL 697 400

Air Care models feature a two-stage air filter which attaches to the back of the humidifier, which filters the air as it humidifies.

The first stage of the air filter is

3M FILTRETETM, 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 carbon 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.
