The packaged unit requires an air filter. The unit does
not come with a factory installed filter rack in it,
however, two filter frame accessories are offered that
will allow the installation of a filter within the unit,
BAYFLTR101 & BAYFLTR201. Otherwise a field
supplied filter rack must be installed by the installer in
the return duct work.
