An Electrostatic Air Purifier/Precipitator and an air purifier using Charged Media Filters work on similar principles. Both collect particles inside the unit.
Electrostatic technology uses electronic cells to charge particles within the purifier and immediately trap them on collector plates. These plates then can be hand washed or sometimes put in
a dishwasher.
The Charged Media technology is of the same principle, but the particles are collected in a filter. This method can collect very small particles (as small as .01 microns). The filters do
require cleaning or replacement as needed.
More Detail:
The particles are charged first, before they pass by the collector plate or collector filter. They are charged negatively (-) or with negative ions and the collector plate or filter is
positively charged (+). Just like opposites attract, the particles now are attracted to the collector mechanisms and stay there. The plates must be cleaned as often as needed or the filters
must be replaced as often as needed. If these capturing mechanisms are not cleaned or replaced as needed, the purifier will become less effective.
Both processes produce "some" ozone. In most cases it is minimal and confined to the inside of the purifier. If the ozone word scares you, make sure to understand how much is
produced and read the ozone technology information before purchasing.

Buying Considerations
There are very good, innovative, low maintenance air purifiers in this category. There are also some that are less than good. My reviews will help. As with any product with filters, do your
cost and filter replacement homework.
