Yet the air inside your home may pose a far greater health risk than the air outside. This isn't hyperbole: the EPA has found that indoor air can be two to five times more polluted than outdoor air, and in some cases, up to 100 times worse. How can indoor air be more polluted than the air we breathe on Manhattan streets or New Jersey highways?
