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

PHI technology throughout the ship, which has helped
eliminate the Norwalk Virus problem plaguing that industry
for years. Thousands of hotel rooms, chain restaurants
and hospitals also utilize PHI technology.
One of the best features is, with well over one million PHI
