Hydroxyl radicals are almost theoretical in that they are so

reactive that they are created and decomposed almost in-

stantaneously. They are typically confined to the reaction

surfaces of the catalyst where they are made. They can

be difficult to control, and accordingly are not always prac-

tical to use for indoor air treatment systems.

Ozone was discovered in the late 1800s in France and has

been used extensively for water and food purification. Un-

like America, Europe prefers ozone over chlorine for water

purification. In the 1980s, ozone began to appear in air pu-

rification primarily as a way to destroy various odors in-

cluding smoke.

Commercial ozone generators are still very popular with
