Actual Dimensions - 19-1/2" X 24-1/2" X 3-3/4"

NOTE: This filter will not fit media filter cabinets (Honeywell, Trion Air Bear, Bryant/Carrier) that require 4-3/8" or 5" thick filters - please measure your existing filter and compare the actual dimensions with the actual dimensions listed above.

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.

Benefits:

  • 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 6 months!
  • Made with pride in the USA

Features:

  • MERV 11 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.

        I actually needed a 5" wide filter but these work fine with a 1" filter placed in front of these 4" filters to catch pet hair.

                  Have used these filters for years, as I have asthmatics in the family. Also as a side benefit, they reduce dusting to almost zero!!!

                      These filters are hard to find in case qty and expensive individually. I've used DiscountFilters for two years now and their service is impeccable.
