Purolator® PURO® Cell Carbon Rigid Box Filters Contain Highly Activated Carbon For High Efficiency In Low Concentration Applications.
Rigid box-type filters provide medium and high efficiency filtration with odor control. Used for air conditioning filters, furnace filters, heating vents, air intakes, air purification devices and ozone removal devices. Eliminates need for retainers and special external wire media supports. High surface area-to-depth ratio provides the maximum amount of effective filter media in areas of minimum in-line duct space. Carbon-loaded pleated box filters clear air by removing molecular contaminants present at levels less than one particle per million. Uniform dispersion of carbon throughout media lets air flow freely. Offers longer filter life with minimal shedding and dusting. Framing is made of high strength, corrosion resistant galvanized steel. Pleat stabilizers are bonded to both air intake and exhaust ends for strength. 90% active, 20 x 50 mesh-size carbon particles for enhanced absorbent surface. Carbon filter is thermally bonded to frame. UL listed.
