30" X 20" X 4-1/2" Pleated Filter (Honeywell)
Quantity in Basket: None
This high efficiency filter mounts in most any standard 20x30 return air grille.
Pleated for greater surface capacity, it provides a MERV 8 efficiency rating and captures particles as small as 0.3 microns! Low pressure drop reduces strain on equipment, provides a comfortable air flow, and maintains equipment efficiency longer than standard filters.
Honeywell recommends replacing the filter every 6 months, or more often if the filter appears dirty to the point of blocking air flow through the heating/cooling equipment.
Note: Honeywell recommends allowing a depth of at least seven inches behind the grille to provide space for the deeper filter and airflow through the filter.
