WHAT AIR CLEANERS DO

AND HOW THEY WORK

ELECTRONIC AIR CLEANERS

OVERVIEW

HOW ELECTRONIC AIR CLEANERS WORK

Electronic air cleaners are by far the most efﬁcient cleaners of indoor air. Unlike standard or media air ﬁlters that merely collect

relatively large particles, electronic air cleaners attract and retain pollutants like a powerful magnet. Using electrostatic precipi-

tation principles, they are even effective on particles so small an electron microscope would be required to see them.

All electronic air cleaners from White-Rodgers clean the air using the following steps. As particles enter the air cleaner, the

larger particles are trapped by the  Preﬁlter Screen (most models), while smaller particles pass through to the  Charging

Section, where they’re given a positive electrical charge by a series of tungsten wires. The charged particles are then drawn

into the  Collection Section. Here a series of positive plates repel the positive particles, and drive them forcefully onto a

series of negative plates, which hold the positive particles like a magnet. Contaminants are held in this section until washed

away during cleaning. In some models the clean air is also circulated through an optional  Charcoal Filter, where odors are

absorbed. The fresher, cleaner air is then discharged from the unit. Electronic air cleaners are 10 to 20 times more efﬁcient

than standard ﬁlters as they remove up to 98 percent of the dirt, dust and smoke that otherwise circulate through the air.
