Better filtration is the first step in improving Indoor Air Quality. Pleated Panel Filters outperform ordinary furnace filters with higher efficiency and lower pressure drop allowing air-handling systems to stay cleaner and operate more efficiently. We achieve this with 100% synthetic electrostatically charged gradient density media, optimum pleat spacing and high initial and sustained efficiency, high dust holding capacity and very low pressure drop. The media is resistant to a wide range of chemicals, does not absorb moisture and will not support microbial growth.


  • Great for helping reduce airborne allergens such as bacteria, particles that carry viruses, pollen, mold spores, fine dust, and pet dander.
  • Filter material will not support the development of mold, mildew, bacteria or other microorganisms in normal use.
  • No chemicals added. Filters are chemical free!
  • Over 30-times more efficient at capturing micro particles than ordinary fiberglass filters.
  • Lasts UP TO 3 months!


  • MERV 8 Rating
  • 100% synthetic gradient media, electrostatically charged
  • 30 gauge galvanized expanded metal grid
  • Moisture resistant double wall beverage board
  • Media pack totally bonded to frame
  • This product is listed and rated by Underwriters Laboratories as U.L. Class 2.

    Comments about IAQ 20" X 24" X 4" MERV 8 Pleated Filter:

    After having a new HAC sytem installed the installer set it up so I would have to purchase a non std. sized 4"X 24x 20 filter from them at $49.00 per. I said no I don't and shopped around found online Discount Filters. Orderd six and had them two days later at a fraction of the price. Very satisfied. Jan
