Air filter pads consist of non-pleated filter media that has been cut to a particular size. They are typically installed into a compatible frame to create an air filter for removing contaminants from the air stream in HVAC systems or paint booth equipment. This prevents the build up of contaminants in the equipment, which can cause damage. It also boosts indoor air quality. Air filter media pads can be cut down to a smaller size, if needed. Commonly used to replace dirty air conditioner filter pads and paint booth filter pads.
