When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and, throat irritation. It may also worsen chronic respiratory diseases such as asthma as well as compromise the ability of the body to fight respiratory infections. Some studies show that ozone concentrations produced by ozone generators can exceed health standards even when one follows manufacturer’s instructions. Many factors affect ozone concentrations including the amount of ozone produced by the machine(s), the size of the indoor space, the amount of material in the room with which ozone reacts, the outdoor ozone concentration, and the amount of ventilation. These factors makeit difficult to control the ozone concentration in all circumstances. Available scientific evidence shows that, at concentrations that do not exceed public health standards, ozone is generally ineffective in controlling indoor air pollution. The concentration of ozone would have to greatly exceed health standards to be effective in removing most indoor air contaminants. In the process of reacting with chemicals indoors, ozone can produce other chemicals that themselves can be irritating and corrosive." <a href="http://www.epa.gov/iaq/pubs/ozonegen.html#harmed" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.epa.gov/iaq/pubs/ozonegen.html#harmed" rel="nofollow">http://www.epa.gov/iaq/pubs/ozonegen.html#harmed</a>[/QUOTE]
