FILTER
CARE
Inspect the air filter(s) at least once a month. If they are dirty, wash
reusable filters with a mild detergent
per manufacturer's
recommenda-
tions. Replace disposable filters with new filters.
Install the clean filters with "air flow" arrow in the same direction as the
air flow in your duct. Filters should be clean to assure maximum
effi-
ciency and adequate air circulation.
Drapes, furniture or other obstruc-
tions blocking
your supply
and return air grilles will also decrease
efficiency.
