CARE AND MAINTENANCE

WASHABLE ACTIVE CARBON FILTER CARE

HAND WASH ONLY!
DO NOT TUMBLE DRY!
Care Cycle
When the Filter Indicator Light lights up, this
indicates that the filter needs to be cleaned. If
the unit is kept on 24 hours a day then the Fil-
ter Indicator Light will activate in about 2
months.
The Filter Indicator Light is for reference. Clean
the filter as often as necessary when odor
persists.
1
Fill a large container with warm
water, add a mild kitchen detergent
and stir.
Dilute as indicated on the
detergent container.
2
Allow the filter to soak approxi-
mately 30 minutes before wash-
ing.
If the filter surface is
very dirty, scrub with
an old toothbrush.
3
Rinse thoroughly with
clean water
CAUTION
If rinsing in a container,
be sure to rinse 3 to 4
times so that the odor is
rinsed thoroughly from
the filter.
4
Remove excess water
The filter will be saturated with water after
rinsing. To decrease drying time, wrap the
filter in an old thick towel so that excess
water can be removed.
CAUTION
Some carbon may ad-
here to the towel, but it
is harmless.
5
Dry the filter outdoors
if possible in a well
ventilated area.
CAUTION
• The wet filter is heavy. Fix it securely for
drying to make sure it does not fall down.
• The filter takes longer to dry in winter, on
rainy days. Wash it on a day when the
weather is good and dry it in the sun.
Move it indoors at night to prevent freez-
ing.
• Dry the filter outdoors in a well ventilated
area. If dried indoors, the water dripping
off the filter may soil your floor.
• Make sure that the activated carbon has
not shifted to one side inside the filter. If it
has, distribute it evenly with your fingers.
• Let the filter dry thoroughly.
If used while the filter is still moist, then
the air that is exhausted from the main unit
will have an odor. It may take 1 or 2 days
to dry.
6
Reinstalling the Filters.
Reinstall the filters as shown on Page

outlet and press the Filter Reset
Button on the Remote Control.

activated, you will hear a beep sound
that means the unit has been reset.

out automatically.
