The Pre-Pleat 40 range of Disposable Cardboard HVAC Filters achieves the highest dust holding capacity and the lowest pressure drop in the industry.
The heavy-duty frame has diagonal and horizontal support members bonded to the media on the air entering and leaving sides for unsurpassed frame strength. Interlocking corners and positive media-to-frame seal reduces the possibility of air-bypass.
