PermaFlo Gray Rigid Polyester is an antimicrobial filter with Spor-Ax® that prevents mold, bacteria, and mildew growth in damp conditions. It's moisture-resistant, making it a great alternative to hog hair. Frameless, easy to clean, and safe to handle, it's ideal for mist eliminator air filtering. Available in rolls or pads, it's easy to cut.
Non-woven polyester is a synthetic air filter medium with haphazardly distributed fibers, providing excellent strength, stiffness, and longevity. It can trap impurities down to the fiber's core and doesn't require a metal frame for installation.

How to clean your PermaFlo filter

When using water, start by backwashing the filter so that the dirt load on the opposite side can wash out better. Keep the dirty side facing down when placed in a sink, on the ground or grate.
Once all dirt is washed out, wait for the filter to dry. Do not use soap, only use water. Do not twist or fold the filter to drain. The media will not absorb moisture, which makes it easy to clean and dry quickly.
Another alternative is to use a shop-vacuum to clean both sides of the filter.
Stabilizing Frame For Any Filter Media

Galvanized steel metal pad stabilizing frames with an enlarged metal support grid on one side are offered. This can be utilized in air filtration applications that need changing out media pads. The air filter media is held in place by two criss-crossed wire supports, which are available with or without the filter frame.
