Practical Pleat 2" MERV 8

The Practical Pleat  is a 5” high performance filter designed to replace inferior 1” filters. Its unique gasket fits into one-inch filter grilles with the excess depth of the filter protruding into the duct system.

However, some units may not be able to accomidate a 5" retrofitted filter. For units that cannot, Filtraiton Manufacturing offers a 2" version of our Practical Pleat Filters. The 2" Practical Pleat is available in MERV 8 rated filter. 

Don’t let the competitors fool you! The Practical Pleat is the only retro-fitting filter that has its’ unique gasket to prevent air bypass. Gaps between the filter and filter frame allow particles to be pulled around the filter, entering the duct system and ultimately, inhabited spaces. 
The “Practical Pleat’s” unique patented gasket conforms to imperfections in the filter track, eliminating air by-pass, and preserving the integrity of the MERV 8.

The Practical Pleat is available in a 5" MERV 11 or MERV 14 rating with 14 standard sizes and custom sizes up to 24”x60”.
