CARE AND MAINTENANCE
WASHABLE ACTIVE CARBON FILTER CARE
Care Cycle
We recommend to the active carbon filter every six months.
Clean the filter as offen 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.
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.
HAND WASH ONLY!
DO NOT TUMBLE DRY!
5
Dry the filter outdoors if possible in
a well ventilated area.
2
Allow the filter to soak ap-
proximately 30 minutes be-
fore washing.
• 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 freezing.
• 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.
