18x18x1 Electrostatic Washable Permanent AC Furnace Filter Replaces standard 18x18x1 sized disposable filters. Standard filters are generally undercut 3/8 inch. The actual size of this filter is 17-5/8 x 17-5/8 x 7/8 These filters retail elsewhere for $79.99-$99.99. Clean your indoor air of allergens like pollen, dust, mold spores and pet dander. Electrostatic filters are designed to build a natural static charge as air passes through them. Unlike paper or fiberglass filters, electrostatic filters actually attract and hold dust particles until they are washed out. Be Careful! Not all electrostatic filters are the same! It is very important that air filters have LOW AIR RESISTANCE so they don't make your central air unit work harder. This can lead to higher energy bills and eventual damage to your HVAC unit. Our filters feature a low 0.12 WG air resistance rating. If you clean our filters regularly (every 30 days), they will clean your air and protect your air handler. Easy to Clean -- These filters are tough and can be vacuumed off, hosed off outside (or in the tub/shower) or cleaned with compressed air.
