Adults breathe in something like 35 gallons of air a day, taking some 20,000 breaths in a 24hr day, most of them in our home. While there are numerous agencies out there attempting to regulate the quality of outdoor air, and to some extent our air in the office, the health of the air in our home has been pretty much left up to the homeowner. Common sources of indoor air pollutants in the home such as dust and mold, but also VOCs-volatile organic compounds-in paints, household cleaners, as well as pesticides, lead dust or asbestos particles in older homes, and any number of other less obvious culprits -- like air fresheners, scented candles and, well, your clothing. Products stored in garages and basements often attribute to higher VOCs.
