How does indoor air compare to outdoor air?
• Indoor air can be as much as 100 times more polluted than outside air. These pollutants pose serious environmental exposures to people. • Studies by the EPA and other researchers have found that VOCs are common in the indoor environment and that their levels may be ten to thousands of times higher indoors than found in the outdoor air. There may be anywhere from 50 up to hundreds of individual VOCs in an indoor air sample.
