Product Details
12x12x3 MERV 11 Return Air Grille Filter, 2-Pack
This specialty filter is designed for use in return grille applications. Many homes have filter grilles, located at the return air openings, that accommodate a one-inch filter. Because of the one-inch limitation homeowners are limited as to their choice of filters, without retrofitting their systems. A one-inch filter by nature has low surface area and needs to be replaced often. Higher efficiency one-inch filters load with dirt quickly and can restrict airflow.
This 3" return grille filter replaces the 1" filter without any retrofitting. A self-sealing foam gasket surrounds the filter on the upstream size and makes a tight seal with the grille surface, eliminating air bypass.
FEATURES:
- Designed to fit into 1" return air filter grilles and replace standard 1" filters
- Self sealing flexible gasket around upstream edge of filter eliminates air bypass
- MERV 11 efficiency rating - captures allergens like dust, mold spores, pet dander, dust mite debris and other airborne particulates
- Superior performance and service life over 1" filters
- Replaces Honeywell part number FC40R1094
- Outside dimension including gasket - actual size 12" X 12" X 3"
- Inside dimension - actual size 10 3/8" X 10 3/8" X 3"
