Electrostatic Filter Magnet

Our Electrostatic filters act like dust magnets. They clean your indoor air of allergens like pollen, dust, mold spores and pet dander. They 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.

All filters come with Lifetime Warranty.

Your satisfaction is 100% guaranteed!

These permanent, washable air filters remove up to 95% of airborne allergens and contaminants and feature low air resistance.

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 30-60 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.

The Electra 9400 is designed to provide high dust arrestance and low air resistance. Two layers of woven monofilament polupropylene with integral anti-microbial material provides 10 times more filtration than a disposable fiberglass filter. The deep loading center layer of non-woven polyester allows the Electra 9400 to prolong the time between washings.


Above, you will see a drop down menu that allows you to choose from 3 different frame styles:

The Standard Metal frames are silver colored, made from stainless steel with silver metal mesh and grey filter media.

The Deluxe Gold frames are made from premium quality extruded stainless steel, with a durable and attractive Gold Anodized finish, silver mesh and black filter media. The extra-strong gold frame is best for large filters.

The Flexible frames are used for applications where a rigid frame will not fit. The edges of the filter are woven and the filters will bend and twist.
