GrilleFilter Product Info:

REPLACES YOUR 1" FILTER & LASTS ONE WHOLE YEAR!

The Return Air Grille Filter’s “knife-edge seal” flange replaces the typical 1” filter that is used in return air grilles. The filter then extends into the open space behind the grille to greatly increase filer area - up to five times that of a 1” pleated filter and nine times that of a flat media filter. The result is fewer filter changes, reduced energy costs and less strain on the HVAC equipment. Available in MERV 8, MERV 11, MERV 13 and Odor Shield.

Product Features:

• Filtration up to 15 times more effective than a standard 1” filter.*
• Fits in most 1” residential wall or ceiling mount return grilles.
• Lasts up to six times longer than standard 1” filter.
• Deeper, more surface area captures particles as small as 0.3 microns.
• Reduces airborne particles like dust, pet dander, mold spores and bacteria.
• Less strain on heating and cooling systems.
• MERV 8 / MERV 11 rated per ASHRAE test standard 52.2.

* Based on initial efficiency analysis of new filters tested at 3-10 micron particles at 492 feet per minute of airflow
