Most common air pollutants in America

Americans concerned about the presence of air pollution in their community can monitor the posted concentrations of the six most common pollutants in the United Stated. The Environmental Protection Agency tracks levels of ozone, particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide and lead.

The Clean Air Act requires the EPA to set National Ambient Air Quality Standards for these six pollutants because they can be harmful to people's health and the environment and even cause property damage. These pollutants are tracked in two ways: by air concentration levels based on actual measurements of pollutant concentration in outside air at selected monitoring sites and by emission estimates made by experienced engineers and scientists.

The limits based on human health requirements are referred to as primary standards. Another set of regulated levels, called secondary standards, is intended to prevent environmental and property damage.

By investing in a home air purifier, a person can further limit the presence of common air pollutants in his or her house. The IQAir HealthPro Plus Air Purifier can improve air quality within a home and help everyone remain safe and healthy.
