Genuine Honeywell Return Grille Filter # FC40R1003

Secure, online ordering, and to-your-door-delivery - it's a snap to order genuine Honeywell 20x20 return air filters.

Honeywell recommends replacing the filter every 12 months, or more often if the filter appears dirty to the point of blocking air flow through the heating/cooling equipment.

Pleated for greater surface capacity, it provides a MERV 10 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.

Your best discount is to order more than one filter.

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.
