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!
