Pad and Frame Air Filter (1 Frame and 6 Pads) - 17 1/2" x 17 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

A higher MERV rating means that the air filter that you are about to purchase possesses a higher amount impurity filtration ability than your ordinary filter

The "Practical Pleat" media is up to 28 times more effective at capturing particles than standard fiberglass panel filters

the greater it's resistance to airflow

oxidation and deterioration

The A+2000 line is easy to maintain with no need to buy oils or adhesives to enhance effectiveness

and long service life which reduces HVAC equipment maintenance and energy costs

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

degrade and restrict air flow

and the greater the pressure drop it creates

Filtering inserts are shipped in an easily stored packet

some just refer to them as electrostatic filters

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