Pad and Frame Air Filter (1 Frame and 6 Pads) - 19 3/4" x 21 1/2" x 1"Includes one Frame and PACK of 6 pads The Pad and Frame Air Filter involves a permanent frame and replaceable filtration pad inserts. The permanent frame is constructed of space age plastics that are resistant to corrosion, oxidation and deterioration. Filtering inserts are anti microbial and are more efficient in capturing particles, such as dust, ragweed, pollen, etc., from the air stream, than standard fiberglass filters purchased at retail

In general

with each stage capturing progressively smaller particles inside the filter

the greater it's resistance to airflow

We can make custom air filters in heights and widths ranking from 6 inches to 36 7/8 inches with increments in 8ths of an inch

And there are no metal parts that could lead to corrosion or oxidation within the filter

degrade and restrict air flow

Because we specialize in custom air filters

the A+2000 uses no foam that may clog

Instead of face loading (particles captured on the outer surface of the filter)
