Polyester Air Filter Pads fulfill most HVAC general filtration requirements. Polyester filters are frequently used to replace fiberglass filters, which can fragment and send glass slivers into the airstream. Polyester is soft, easy to handle and offers higher arrestance and dust holding capabilities than most fiberglass filters. Purchase by the square foot.
