Poor Indoor Air Quality Can
Threaten Your Health

Most people spend over 90% of their time indoors, not knowing that the air they are breathing may be more polluted than the air outside. The Environmental Protection Agency has reported that indoor air pollution levels can be 100 times higher than the air outdoors.

Breathing contaminated air puts the health of you and your family at risk. In fact, the American College of Allergist says that 50% of illnesses are caused or aggravated by polluted indoor air. So take control of your indoor air quality by reducing pollutants that can contribute to headache, lung irritation and fatigue as well as more long-term conditions such as asthma, allergies and infectious diseases.
