How does an electrostatic air filter work?
The Air Filter Store’s electrostatic air filters utilize a patented configuration of alternate polarity, self-charging layers of polypropylene filtration media, to attract particles as small as 1 micron, 1 micron = 1/25,000 of an inch. Just like opposite poles of a magnet attract one another, a positively charge dust particle is attracted to the negatively charged polypropylene media of the filter. This electrostatic property is what gives our air filters the the high efficiency that ordinary disposable filters just can’t match.
