In a recent survey conducted by Johns Manville and reported in Appliance Magazine, U.S. homeowners believe the air inside their homes is cleaner than a
ir outside their homes. But, of course, the EPA believes that the air inside buildings can be more seriously polluted than the outdoor air.
This survey found that 65.7% of homeowners are concerned or very concerned about indoor air quality, and homeowner strategies for improving indoor air quality include:
• Purchasing an air purifier - 23.7%
• Cleaning heating/cooling duct - 23.6%
• Upgrading furnace or heating system components - 16.7%
• Making ventilation improvements - 15.8%
• Eliminating or reducing sources of indoor air pollution - 8.6%
• Not taken any steps to improve IAQ - 37.7%
