Key item features

  • WHOLE HOUSE REPLACEMENT: 20x20x5 air filters for your furnace, air conditioner, or heat pump enhance HVAC system efficiency and support a healthy lifestyle (actual size: 19.63" x 19.88" x 4.38")
  • MERV 11 PERFORMANCE: Protect your home or business from allergens, pets, and more with MERV 11 synthetic media (comparable with MPR 1200 & FPR 7) that captures 95% of dust without restricting air flow
  • LONG-LASTING FILTRATION: Electrostatically charged media (made in the USA) with 8 pleats per foot traps more microscopic particles and lasts 3x longer than fiberglass models (replace every 90 days for optimal performance)
  • SUPERIOR CONSTRUCTION: Easy installation beverage board (recyclable) frames with dual wire backing outperform flimsy cardboard designs by improving durability, preventing warping, and resisting extreme temperatures
  • COMPATIBLE MODELS: Honeywell / Air Demon Filter Part Numbers F25 (#203721), F35 / F35R (#FC35A1019), F100 / F150 (#FC100A1011), F200 (#FC200E1011), Lennox (X0585, X8305, X8308), Collection Cells (F25F1018, F35F1016, F100F1020, F50A1124, F50A1165, F50E1026, F50E1182, F50E6124, F50E6165, F50E8021, F50E8062, F50F1107, F50F1040, F55A1244, F55A1426, F55A1459, F55F1029, F55F1052, F58A1050, F58F1026, F300E1027)

Great Filter

These filters work great. The filter arrives every six months to the date that it's time to replace. I don't have to think or worry about when to replace the filter. One less worry. This filter is definitely high quality.

Great drop-in replacement for 5" Trane OEM filter

These filters are well made. They are perfect fits for drop-in replacement for 5" Trane filters. Note that there is a big drop in price for buying more than one filter at a time.
