The polluted air in your homeDavid Papazian/Shutterstock
People tend to focus on the dangerous particles in the outdoor air—and for good reason: check out what air pollution can do to your body. But the air in your house can be up to five times more polluted than what you’re breathing outdoors, according to the Environmental Protection Agency. And don’t forget you spend up to 90 percent of your time indoors, reports the American Lung Association. That’s a lot of exposure to potentially contaminated air.

Now that energy-efficient buildings keep air leakage to a minimum, there’s a big uptick in the concentration of air pollutants, says Ian Colbeck, PhD, professor in the school of biological sciences at the University of Essex. Pollutants that should pique your concern include tobacco smoke, nitrogen dioxide, carbon monoxide, particulate matter agents, formaldehyde, volatile organic compounds (VOCs), and radon, he says.
