Negative ions are particles that are electrically charged by adding an excess of electrons to the particle. The negative ions interact with chemical compounds and micro organisms in the air.

They literally attach themselves to the contaminated particles and destroy them. Ozone is released as a by product. Ozone has beneficial antiseptic qualities but must be produced at low levels.

Ozone is often considered to be bad when produced by air cleaners. However, ozone can be used to kill micro organisms and is highly effect in combating volatile organic compounds (VOCs).

There may also be an activated charcoal filter that removes odors from the air passing through it.

An option offered by several manufacturers is an ion generator that can be added to the unit and can be turned on or off at will. This adds a fresh scent to the room as well as an additional air cleaning capacity.
