• The Dust Free® self-charging electrostatic air filter can re-move symptom-causing dust, pollen, mold, and dander, as air circulates through your central air system. • Regular maintenance will keep your Dust Free® air filter operating at peak efficiency for a lifetime. Simply wash your filter with house-hold detergent and water every 30-60 days. • High performance filtration will help keep dust and mold from accumulating in the air handling unit. If your system has been in operation for a long period of time with a low efficiency filter, the coils and drain pan may need to be inspected. Your experienced service contractor is the best qualified person to provide this valuable service. • Pull tabs make it easy to remove filter for routine cleaning and maintenance. • Durable wire keeps the filtration media in place in even the most powerful central air systems. • High-strength extruded aluminum frame for maximum durability. • Tiny airborne particles are captured by the electrostatic fibers as seen in this magnified image of filter media after one weeks use. • Each multi-layer air filter uses a patented configuration of woven filtration media plus a medical quality, anti-microbial, foam core which inhibits mold and bacteria growth. • Unique design makes it possible to have the filter factory resized and reconditioned should you move or buy new HVAC equipment. This protects your investment. • Filter Size: 20" x 25" x 1"
