The return grille filter provides a high-efficiency, long life alternative to a 1 in filter. Our patented design, unique to the industry, captures a significant amount of the airborne particles, in the air that circulates through the filter.

- Efficiency ratings are based on American society of heating, refrigerating and air-conditioning engineers standard 52.2 1999
- Efficiency ranges are defined for small particles E1=0.3 to 1 um, medium particles E2=1 to 3 um and large particles
- Mounts in most third-party return filter grilles
- Provides high-efficiency alternative to 1 in filter
- Easy installation
- Pre-assembled filter easily inserts into and out of existing return grille
- Exclusive frame design nests properly into place
- Low pressure drop reduces strain on equipment, provides a comfortable airflow and maintains equipment efficiency longer than standard filters
- Captures up to 85% of particles passing through the HVAC system
- Up to 10 times more effective than standard 1 in filters
- For most 1 in ceiling or wall-mount return grilles with 18 sizes to choose from
