DustEater Washable Electrostatic Air Filters

Dusteater air filter logo


The DustEater® Air Filter series is proven in independent laboratory testing to provide highly efficient system-wide air filtration with low resistance to airflow.

Utilizing two electrostatically charged fabric panels separated by our unique ACCUMULATOR CHAMBER® produces a very effective three-stage air filtration process for residential applications.

Below you will find more information on our DustEater Air Filters including our:

  • DustEater Allergy Relief (Model DE) and
  • DustEater Easy Flow (Model EF)

Washable Electrostatic Filters for Residential Use

Permatron's DustEater is arguably the most effective washable electrostatic air filter manufactured in the U.S.A. for residential use. Whether for standard furnace sizes, or custom built to meet a specific requirement, DustEater is an extremely effective electrostatic air filter for use in the home.

The first air filter media panel (the prefilter) attracts and holds airborne particulates. The filter fabric's inherent electrostatic charge enhances filtration by drawing particulates onto fiber surfaces like a magnet. Static electricity does not discharge over time because the air flow helps it maintain the charge - nor does it require insulation or grounding.

When particulates build up on the DustEater's prefilter, airflow forces them to break off and collect in the ACCUMULATOR CHAMBER, where turbulence and electrostatic forces cause agglomeration into even larger particulates. These agglomerated particulates are too large to pass through the second panel (the afterfilter).

DustEater's afterfilter attracts and holds the smaller particulates that may have escaped the prefilter, or particles that do not respond to an electrostatic charge.

DustEater Air Filter Models

The DustEater (Model DE) and DustEater Easy Flow (Model EF) are significantly more efficient than standard disposable air filters. Standard disposable filters trap only very large particles. Not only are these filters less efficient but they tend to clog, restricting airflow which results in increased heating/cooling costs. DustEater is environmentally friendly with no disposable parts.

Our DustEater line of filters is available in two models to meet any requirements:

DustEater Allergy Relief Air Filter - Model DE

The DustEater Model DE, our allergy relief air filter, contains a combination of polypropylene and non-woven polyester for increased arrestance efficiency, wire reinforced in a stainless steel frame.

Dusteater Easy Flow Air Filter - Model EF

The DustEater Easy Flow (Model EF), low resistance to air flow air filter, contains polypropylene and wire reinforced in a stainless steel frame. The Easy Flow model is ideal for heat pumps, sensitive 90+ furnaces and older systems with limited air flow.
