The Perm A Foam Filter consists of PPI 20 foam with aluminum expanded on both sides. The media is corrugated in between layers of aluminum expanded. This creates high dust holding capacity and low resistance. The media consists of 1/8” Scott foam, corrugated between two layers of aluminum mesh.

Providing up to 40% more filtering area, this metal HVAC filter has a higher dust holding capacity than the flat faced foam filter. Designed for applications such as industrial, commercial, schools, office buildings, and hotels where a permanent filter is recommended. These filters are often used with electronic equipment.
