Pleated Panel Filters have higher efficiency and lower pressure drop allowing air-handling systems to stay cleaner and operate more efficiently. Pleats extended surface pleated filter from filter outperform ordinary furnace filters with medium efficiency and are designed for lower pressure drop, and long service life which reduces equipment maintenance and energy costs.

Extended-surface filters provide high efficiency odor removal and particulate collection for a variety of applications. The filters use Carbon Web filter media containing 60% activity granular activated carbon to remove odors and gaseous pollution. The media is pleated and housed in a rigid metal frame. The frame is available in either the standard box style, no header version or with a single 13/16" thick header.
