Description

20" X 20" X 1" Low-Resistance, Electrostatic Permanent Washable Filter

(actual size - 19-1/2" X 19-1/2" X 3/4")

Never buy another filter!  Our permanent washable filter is designed to provide great value and last a lifetime.   This durable filter is constructed with a combination of woven polypropylene media supported by heavy-duty steel mesh in a galvanized steel frame. The filter carries a lifetime warranty and is ideal for heat pumps, sensitive 90+ efficient furnaces and systems with limited air flow.  This is the best and last filter you will ever buy.

FEATURES:

  • Designed to minimize initial resistance to airflow
  • Reduces the number of pollutants and allergens in recirculated air and keeps your HVAC system clean
  • Uses natural static electricity to attract and capture airborne particles
  • Washable - cleans up in minutes
  • Includes anti-microbial polymeric protection
  • Durable steel frame
  • Dirt won't get caught in the filter during washing - due to specially-designed drainage ports in the filter frame
  • Lifetime warranty

CLEANING INSTRUCTIONS:
Clean Monthly by rinsing your filter with running water.  For tough dirt and/or grease, use a mild detergent (i.e., 409 or Simple Green) and rinse thoroughly with warm water.

SPECIFICATIONS:
Average arrestance efficiency - 74%
Initial resistance - 0.07" w.g.

    Comments about Permatron 20" X 20" X 1" Lifetime Permanent Washable Filter:

    Permatron makes much better models: Dusteater and Easyflow. This one is the fourth or more in lineup... Spend few extra bucks and get the Dusteater or EF, better filtration, better MERV rating, Stainless Steel frame (not Galvanized), better box fit, same Lifetime guarantee....I would not recommend this particular model to a friend, but another model also from Permatron!

      Comments about Permatron 20" X 20" X 1" Lifetime Permanent Washable Filter:

      Shipped quickly and very pleased with product. Only negative is when the ac unit blower stops there is a small rattle from the filter where it rests inside the vents. Easy fix was to put double sided tape to prevent the filter from moving. Otherwise I have no issues!

        Wash filter once a month, but could wait 3 months easily.
