Many people assume that outdoor pollution caused by cars and factories is rampant, meaning we should spend more time indoors for better respiratory health. But it may surprise you to learn that, according to the Environmental Protection Agency, indoor levels of pollutants are often two to five times greater than outdoor pollutants—in some cases more than 100 times higher than typical outdoor concentrations.
Couple that stark fact with this alarming stat: We tend to spend around 90% of our time indoors.
Consider that poor indoor air quality can seriously affect your health, causing or worsening allergies, asthma, and other respiratory problems. Polluted indoor air has various sources, from everyday dust and pet dander to mold spores and harmful chemicals from cleaning products.
