What is an Electrostatic Filter?
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.
Electrostatic air ﬁltration can remove symptom-causing dust, pollen, mold, and
dander, as air circulates through your central air system.
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
- Limited Lifetime warranty
- Integral part of whole house air
- Compatible with all HVAC systems
How it Works
Our 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.
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 Dust Freer filters
are able to capture include house dust, lint, animal dander, pollen, mold
spores, and skin flakes.
