Description
The Lennox 97L87 Pleated Air Filter 24″ x 24″ x 2″ is a MERV-11 rated filtration component used to capture airborne particles as air circulates through return duct. It is installed in commercial air handlers to reduce dust, pollen, and fine debris before air reaches the blower and evaporator coil. The filter supports system efficiency by limiting buildup on internal components and airflow balance in HVAC systems. It is mounted within the filter rack or return grille as part of routine air handling maintenance, and it is periodically cleaned according to operating conditions.
