These filters achieve a MERV 10 rating per the ANSI/ASHRAE 52.2 Test Standard. These pleated filters incorporate media which is laminated to a galvanized metal that stabilizes the media during operation. The pleats are formed in a radial configuration to ensure proper dust-loading capacity. The standard pleated cartridge is bonded into a two-piece heavy-duty beverage board die-cut frame that creates a double-wall thickness around the filter. The die-cut grilles are internally bonded to the pleat apexes on both sides to ensure maximum integrity and support during the life of the filter. Pleated filters are used in a broad range of installations, from pre-filters to primary filters for homes, business, schools, apartments, hotels and hospitals.
