Care And Maintenance; Removing Scale - Essick 447 400HB OAK BURL 4 SPD Owner's Care & Use Manual

OPTIONAL AIRCARE® FILTER
The optional AirCare® filter is a excellent means of cleaning the air while using
your humidifier. 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 is an activated carbon media which absorbs odors from cooking, pets, or
tobacco smoke.
We recommend replacing the AirCare® filter at least once a year and more often if
necessary. When the white filter media is coated with a layer of dust and dirt, it is
time to replace the AirCare® filter. The certified water output of your humidifier will
be reduced when using the AirCare® filter. AirCare® filters are optional and are
not required for normal operation of the humidifier. AirCare® is registered
trademark of Essick Air Products.

CARE AND MAINTENANCE

Cleaning your humidifier regularly helps eliminate odors and bacterial and fungal
growth. Ordinary household bleach is a good disinfectant and can be used to wipe
out the humidifier base and bottle/reservoir after cleaning. We recommend
cleaning your humidifier at least once every two weeks to maintain optimum
environmental conditions for your home.
We also recommend using Essick Air Bacteriostat Treatment each time you refill
your humidifier to reduce bacterial growth. Add bacteriostat according to the
instructions on the bottle. Please call 1-800-547-3888 to order Bacteriostat
Treatment reference part number 1970.
1. Turn off unit completely and unplug from outlet.
2. Lift out the water bottles and the power pack.
3. Carry bottles and base to cleaning basin. Lift wick from the base allowing the
water to drain. Rinse wick under fresh water only. Do not use soap, detergent,
or any other cleaners on the wick. Leave in sink to drain.
