Honeywell FR8000F2025 Media Filter for TrueCLEAN Air Cleaner - Fits in FH8000F2025 Air CleanerActual Dimensions - 20-5/8" X 24-1/2" X 3-9/16"The Honeywell TrueCLEAN Enhanced Air Cleaner is designed for use in return air duct of a forced air heating, cooling and ventilation system. TrueCLEAN provides extremely high filtration performance while destroying captured contaminants, including viruses, bacteria and mold spores. The Honeywell TrueCLEAN Enhanced Air Cleaner treats the entire air stream through a state of the art three-step process. -Charge: In stage one particles in the air are electrically charged by an array of ionizer points as they enter the air cleaner. -Capture: In stage two the charged particles are electrically attracted and captured in the filter cartridge which is located within an electric field. -Destroy: In stage three captured particles are destroyed by electrical current flow and ion bombardment.Specifications:Description TrueCLEAN Replacement FilterApplication Replacement FilterDimensions (in.) 20 in. x 25 in.Dimensions (mm) 508 mm x 635 mmAirflow Max.-Capacity (cfm) 2000 cfmAirflow Max.-Capacity (m³/hr) 3400 m³/hrEfficiency Standard Efficiency ranges are defined for small particles, E1=0.3 to 1.0 microns; medium particles, E2=1.0 to 3.0 microns; and large particles, E3=3.0 to 10.0 microns.Efficiency Standard Efficiency ratings are based on American Society of Heating, Refrigerating and Air-Conditioning Engineers Standard 52.2-1999.Efficiency Standard Efficiency rating of filter as installed.Fractional Efficiency E1=90%, E2=96%, E3=99%Minimum Efficiency Reporting Value (Media Filters Only) MERV 15Static Pressure Drop (in. w.c.) 0.25 at 500 FPMType or Air Cleaner Enhanced Air CleanerApprovals, Underwriters Laboratories Inc Filter Element: UL900Approvals, Canadian Standards Association Filter Element: UL900Used With FH8000F2025
