Indoor Air Quality: Causes Of, Testing, and Monitoring Indoor Air Pollution

Testing for poor indoor air quality
Aside from keeping known pollutants out of our homes, there are several strategies for keeping the indoor air healthy.

Keeping pesticides out of your garden and off your lawn can also help, as they're easy to track in on shoes and clothing. It's also important to keep filters and vents clean, as pollutants can cycle through air ducts and central heating and cooling mechanisms.
