About this product
MERV Rating Filter Type Washable Cleaning Frequency Warranty Sizes Available
MERV 6 Electrostatic (Permanent) Yes — Rinse & Reuse Monthly (rinse with running water) Lifetime 25 Standard + Custom Sizes

If you or someone in your family suffers from allergies, you'll be happy to know that the DustEater whole house filter from Permatron is the best furnace / central air filter to capture dust and airborne particles.

For over 30 years, the DustEater whole house air filter has been the most effective, washable electrostatic air filter manufactured in the U.S.A. Available in 25 sizes, DustEater air filters will trap more dust and indoor particles than any other furnace filter available. What's more, they're completely washable and are backed by a lifetime warranty.

DustEater HVAC Furnace Air Filter Accumulator ChamberThe DustEater furnace air filters feature the exclusive Accumulator Chamber®. This unique filter bank design combines multiple sets of steel-framed media assembled with deliberate separation to create a triple-action filtration system. This pre-filter/after-filter strategy promotes free airflow with a superior dust holding capacity while resisting face loading. Excess particles sweep through the prefilter. Airflow combined with static electricity within the chamber causes further agglomeration and collection until the filter is rinsed clean. The outer steel frame of the DustEater filter contains strategically placed drain holes for thorough cleaning.

DustEater Whole House Electrostatic Air Filter is the Ultimate HVAC Filter for Allergy Relief

  • DustEater is the ultimate allergy relief filter, containing an added layer of non-woven polyester for maximum arrestance efficiency.
  • DustEater features a combination of polypropylene and non-woven polyester media with expanded wire support, within a triple frame construction.
  • DustEater attracts and holds airborne particulates, reducing contaminants, so you can breathe easier and your HVAC can run efficiently.
  • DustEater is permanent. It's a cost-effective way to significantly improve the quality of your air, independently tested, and proven effective for over thirty years.
  • DustEater is washable. Simply rinse monthly with running water — no replacement filters to buy, ever. Backed by a Lifetime Warranty.

Frequently asked questions

Will a DustEater filter improve HVAC airflow?
Yes. Clean electrostatic filters maintain strong airflow and help reduce dust buildup on coils and ducts.

Is this better than disposable filters?
It’s reusable, cost-saving, and captures more debris than most standard 1" fiberglass throwaways - but it is not a HEPA filter.

Will it fit my furnace or AC?
Yes, as long as you select the correct width × height × depth for your filter slot.

Does this help with pet dander?
Yes. The electrostatic media captures fine dust, hair, and dander that quickly clog disposable filters.

Can I use it in both heating and cooling seasons?
Absolutely. It’s designed for year-round use in any forced-air HVAC system.

Can I clean it in a dishwasher?
No. Hand-rinse only. Dishwashing can damage the electrostatic layers and frame.
