Indoor air quality risks tends to pose from two to five times more toxins than outside air. The risks can rise during the winter months due to closed house conditions than can concentrate pollutants.
The EPA recommends certain actions to reduce indoor air pollution:
Don't bring in elements that could be a source of health hazards.
Ventilate your home.
Use centrally housed air filters and cleaners.
Restrict the use of hazardous products.
