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.
