Perfect Pleat High Capacity panel filters use unique self-supporting filter media and are constructed with a consistent pleat spacing. At 15 pleats per foot, the increased filtration area results in a lower pressure drop, greater energy efficiency and increased time between filter changes. The high integrity media retains its shape and form. These filters contain no metallic parts and are therefore fully incinerable. The frame has superior class-leading water resistance. Used for Guardian Hepa Air Scrubber.
