The 4-inch Glasfloss MERV 10 pleated allergen reduction electrostatic air filter will enhance the air quality in your home or business. This electrostatic air filter attracts and captures airborne dust, pollen, mold spores, pet dander, smog, dust mite debris, and baking flour. The Glasfloss Z-Line Series pleated filters offer improved performance for virtually every application. All Glasfloss Z-Line pleated filters feature fibers which do not absorb moisture and will not support microbial growth. The Glasfloss Z-Line Series filters achieve a MERV 10 rating per the ANSI/ASHRAE 52.2 Test Standard. The Z-Line Series pleat is available in many standard face dimensions in 1”, 2" and 4" depths. Glasfloss Z-Line Series 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. 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 and prevents air bypass. The die-cut grilles are internally bonded to the pleat apexes on the air-entry and air-exit sides to ensure maximum integrity and support during the life of the filter. Glasfloss Z-Line Series pleated filters are used in a broad range of installations, from pre-filters to primary filters for computer room units. Whether used as primary filters or as pre-filters in multi-stage systems, Glasfloss Z-Line Series pleated filters offer a solution for virtually every residential, commercial, and industrial HVAC application. , 2 Pack of 20x25x4 MERV 10 Pleated 4" Inch Air Filters by Glasfloss.
