Key item features

  • WHOLE HOUSE REPLACEMENT: 20x21x5 air filters for your furnace, air conditioner, or heat pump enhance HVAC system efficiency and support a healthy lifestyle (actual size: 19.88" x 20.50" x 4.38")

  • 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: Lennox Filter Part Number (X8790), Housing Part Number (PCO14-23), Electro-Air (F825-0337 / F8110321, SST 16C28S-010)
