Depending on the installation and/or customer preference,
differing filter arrangements can be applied. Filters can be
installed in the central return register or a side panel external
filter rack kit (upflows). As an alternative a media air filter
or electronic air cleaner can be used as the requested filter.
Consider installing an air cleaner with deep-pleated media
filter at the time of furnace installation. A deep-pleated
filter with a MERV rating of 8 (minimum) will often provide
better filtration to protect equipment and the air distribution
system than a standard 1" filter and often has lower static
pressure loss than a 1" filter. Also a deep-pleated filter will
typically require less frequent replacement intervals. Avoid
using highly restrictive 1" filters which produce static
pressure loss greater than .25" W.C. In some installations
the minimum filter size required will not lend itself to a
filter installation on the side of the furnace. The installation
of a centrally installed air cleaner cabinet or a return duct
filter installation may offer more practicality.
Clean Comfort™ brand MERV 11 air cleaners have 5¼”
media filters and are available in the following configura-
tions. Consult your distributor for information on our
