Homeowners unaware of indoor air pollution
This lack of awareness is illustrated by the belief that unhealthy air can be avoided by staying inside homes and offices during "Code Red" days - days rated as unhealthy by the Environmental Protection Agency's Outdoor Air Quality Index. Americans spend 90% of their time indoors, according to the EPA. The EPA established indoor air pollution is one of the five most urgent environmental problems facing the United States.
Other survey findings include:
- 77% of homeowners have forced air heating or central air conditioning, but 40% do not change air filters every 2-3 months as recommended;
- Only one homeowner out of eight uses a high-efficiency air filter to remove pet dander, dust and other potentially harmful particles from the air, but nearly 60% are willing to spend at least $15 on air filters every three months to improve air quality;
- Only 37% have a carbon monoxide detector in their homes; and
- Only one in 11 homeowners has a radon detector in the home.
