If all room air purifiers sold in the United States were ENERGY STAR certified, the energy cost savings would grow to more than $600 million each year and 10 billion pounds of annual greenhouse gas emissions would be prevented, equivalent to the emissions from more than 980,000 vehicles.

Did you know a standard room air purifier, operating continuously, uses approximately 550 kWh/year in electricity? This is more than the energy used by most new refrigerators. Be sure to look for ENERGY STAR. Over the product's lifetime, you'll save on average $215.
