Electrostatic Filtration

Electrostatic air filters are able to capture many of the allergens that aggravate allergy and asthma symptoms. Pollen, molds, and dust are common in any household and can be reduced by using electrostatic air filtration.

What It Is

Electrostatic air filtration can remove symptom-causing dust, pollen, mold, and dander, as air circulates through your central air system.

The technology uses a patented configuration of woven filtration media plus a medical quality, anti-microbial, foam core which inhibits mold and bacteria growth.

  • Permanent and washable technology.
  • Lifetime warranty.
  • Integral part of whole house air quality program.
  • Compatible with all HVAC systems.


How It Works

The electrostatic air filters manufactured by Dust Free utilize synthetic material which develops an electrostatic charge as friction is applied to the plastic fibers. In the filters case, air flowing through the filter provides the necessary friction.

This can be demonstrated by rubbing the surface of the filter with a cloth briskly and placing the filter over light weight flakes of material such as tea leaves, or styrofoam chips.

The small chips will be attracted to the filter surface and held there due to the charge that developed on the filter as a result of rubbing it. The electrostatic charge that is developed as air passes through the filter, increases the filters attraction to particles such as pollen, molds, and dust.

Monthly washing will keep the electrostatic filtration material operating at peak efficiency. Simply wash with household detergent and water.


Performance

An electrostatic filter is generally effective in capturing particles 1 micron and larger. A micron is 1/25,000 of an inch. Some of the particles our filters are able to capture include house dust, lint, animal dander, pollen, mold spores, and skin flakes
