Description

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

(actual size - 13-1/2" 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.
Dust holding capacity - 110 grams
