When particles such as dust, pet dander and household chemicals pass through the filter, they become polarized. These polarized particles join together to form bigger clusters that are more easily captured and collect on the fiberglass pad with an activated carbon center screen. The activated carbon center media pad is a non-woven polyester base fabric. The carbon media is UL certified for flame retardancy, class 2. The fiberglass media becomes polarized by the charge from the power supply and acts like a powerful magnet to attract sub-micron particles.Don't see your size contact usthrough eBay messages Custom Filters Sizes AvailableManufactured by Fast-Shipped-Filters Caution: Do not place order using the measurement of disposable fiberglass pad. Measure the outside frame or refer to filter label inside plastic channel.Thank you for looking Replacement media air filter pads can also be used in:Aeriale Air CleanerAlpinePure ET for the Water Furnace brand geothermal hydronic unitsBiologic3 Air CleanerClean Air Defense System AirRangerDynamic 1 inch panels P1000Dynamic 2 inch panels P2000Dynamic CT-100Dynamic CT-500Dynamic OH1010Dynamic RS2 1400Dynamic RS2 2400Dynamic RS3 1400Dynamic RS3 2400EarthPure air cleaner for the ClimateMaster geothermal unitsElectro-Filter Air CleanerFreshAire UV PLPGarrison GAR-P6100Green Homes AmericaMicroGuardian AirScrubber® IIINatures Home MicroPower Guard®Natures Home MicroPower Guard® DiamondOne Hour Xenon MicroPower Guard®One Hour Xenon MicroPower Guard® DiamondP6100 Premium Air Quality Specialists Air CleanerPerfect Air Plus Air CleanerPremierOne Pure Flo P6100 Air CleanerPristine Air Air CleanerPureAiRx Air CleanerSolaceAir Air CleanerSpacePak PurePak AC-RBC-2SpacePak PurePak AC-RBC-3SpacePak PurePak AC-RBC-5StratosAire Air Cleaner
