F50F AND F300E ELECTRONIC AIR CLEANERS
How the electronic air cleaner works
First, large particles (lint, hair) are caught by the prefilter(s). Then, as the dirty air
passes through the intense high voltage electric field surrounding the ionizer wires, all
particles, even the smallest particles down to 0.3 micron are given an electric
charge.The air then passes into the collector where the alternate parallel plates are
charged positive and negative, creating a uniform electrostatic field. Since opposites
attract, the charged particles stick to the collector plates, having an opposite electric
charge.The precharged postfilter continues to remove small particles from the air. The
air leaving the air cleaner contains very few particles.

Each time the air circulates through the heating/air conditioning system and air
cleaner, more particles are removed. These particles are generated by normal
household activities and also enter the house from outside. That is the reason we
recommend that you use the air cleaner as much as possible.
Electronic air cleaner vs standard furnace filter
The regular furnace filter collects mainly large, visible particles that reach the filter. Its
main purpose is to protect the furnace and air conditioner blower. The electronic air
cleaner collects these large particles plus many of the smaller, mostly invisible
particles. Its purpose is to reduce indoor air pollution as well as to protect the blower,
air conditioning coils and heat exchanger.
