The levels of air pollutants are often greater indoors than outside, says the EPA and the U.S. Consumer Product Safety Commission, which offer ways to identify air quality problems. The young, elderly and chronically ill, especially those suffering from respiratory or cardiovascular disease, are most susceptible to the effects of indoor air pollution, according to the agency.
Since people spend approximately 90 percent of their time indoors, it’s important to make sure the inside air you breathe is safe and circulating. An air monitor and air purifier, as well as fans and replacement filters, can help.
