How it Works

Dust Free electrostatic air filters 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. Also 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. As a result some of the particles Dust Free filters are able to capture include house dust, lint, animal dander, pollen, mold spores, and skin flakes. Particles and their size in microns

We have many customer who replace their Dust Free electrostatic air filters at about 10 to 20 years, most at 12 to 15 years. Although the initial cost sounds expensive if you divide it by 12 years it usually costs less than $1 a month. A great price for a quality electrostatic air filter.
