I have emphysema and am sensitive to indoor pollutants like cigarette smoke.
Would an ozone generator help?
A. It may do more harm than good. Inhaled ozone can be harmful to health, a
summary of research issued by the Environmental Protection Agency concludes,
adding, "available scientific evidence shows that at concentrations that do not
exceed public health standards, ozone is generally ineffective in controlling
indoor air pollution."
In particular, inhaled ozone can damage the lungs, according to the E.P.A.
Relatively low amounts can cause chest pain, coughing, shortness of breath and
throat irritation, and ozone may also worsen chronic respiratory diseases.
The oxygen we need for life is O2, a molecule composed of two atoms of
oxygen. Ozone, O3, has three atoms and is highly reactive, because the third
atom can detach from the ozone molecule and reattach to molecules of other
substances. But this reaction would take too long to be effective for most
pollution and would not remove contaminating particles. Meanwhile, the very high
ozone levels that might remove some pollutants would also irritate delicate lung
tissues.
The E.P.A. says that it is more effective to control the source of pollution,
to improve ventilation, and, as a supplement, to remove pollutants through
proven air cleaning methods, like filters and electronic particle precipitators.
