Secure, online ordering, and to-your-door-delivery - it's a snap to order genuine Honeywell 20x20 return air filters.
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.
Save when you buy more than one. Save even more on a master carton of 5, listed below!
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.
Note: Honeywell has changed the depth of their return grill air filters from 4-1/2 inches down to 3 inches. Due to existing item inventory you may still receive a 4-1/2 inch filter.
