Ozone, a lung irritant, is produced indirectly by ion generators and some other electronic air cleaners and directly by ozone generators. While indirect ozone production is of concern, there is even greater concern with the direct, and purposeful introduction of a lung irritant into indoor air. There is no difference, despite some marketers' claims, between ozone in smog outdoors and ozone produced by these devices. ...

| ozone |
Formed in the presence of sunlight from hydrocarbons and nitrogen oxides that are emitted from the burning of fuels. While ozone protects us from ultraviolet rays in the stratosphere located 20 miles above the earth, we are now forming ozone, because of air pollution emissions, in the lower atmosphere in which we breathe. Ozone is a strong oxidizer and directly attacks the lungs and mucous tissue. It is especially bad for asthmatics and people with other respiratory problems.

| ozone |
is found in two places, in the upper atmosphere and at ground level. It is the upper level of ozone that acts as a greenhouse gas -- this ozone occurs naturally. Man-made ozone is found at ground level, and is a byproduct of burning fossil fuels (CO reacts with N 2 O and sunlight to produce O 3 ). Ground level ozone is too short-lived to be a greenhouse gas, but it is a siginificant toxic air pollutant.
