Glasfloss Air Filter 20x24x4 - 4" MERV 10 - (Pack of 4) - AC or HVAC Pleated Air Filter - Furnace Air Filter - for Home or Office - Made In The USA.

Product Description.Glasfloss Z-Line MERV 10 Furnace Air Filters (1”, 2” & 4” thicknesses)Extended Surface Pleated Media, Rugged Design, Low Pressure Drop, High Energy Efficient.The Glasfloss Z-Line Pleated HVAC or AC Furnace Air Filters offers superior performance with MERV 10 rating (Minimum Efficiency Rating Value). Due to the higher MERV 10 rating value, it holds more Micro Dust Particles, Lint, Mold, Pollen, Debris, Dust Mites & Bacteria compare to MERV 8 air filters available in the market.PROVEN TEST RESULTS: ALL the Glasfloss Furnace Air Filters are rigorously tested by third party under ANSI/ASHRAE 52.2 test procedures for MERV rating value 10, 11 & 13 respectively. The Glasfloss Furnace Air Filters are classified per UL Standard 900 for flammability requirement and maximum operating temperature limit is 1800F (820C).EFFICIENT V-PLEATS DESIGN: The Glasfloss V-Pleats design increase the surface area of contact with Air Flow hence collect maximum Micro Dust Particles, Lint, Molds, Bacteria, Pollen and Debris. It offers less resistance to air flow which save in energy cost and increases AC unit life.FILTER MEDIA SUPPORT/FRAME: A heavy duty, galvanized, recycled expanded metal reinforcement which is laminated to the air filters exit side of the media by Thermosetting Adhesive to maintain the structural integrity of the radial pleats. An eco-friendly, two-piece, moisture media to avoid air leakage from filter assembly.APPLICATIONS: The Glasfloss Z-Line MERV 10 (1”, 2” & 4”) Furnace Air Filters are excellent choice for Residential Homes, Commercial Buildings, Hospitals, School/Universities, Data Centers, Laboratories and many industrial applications for pre-filter use.
