Room air purifiers - sometimes referred to as "room air cleaners" - are portable, electric appliances that remove fine particles, such as dust and pollen, from indoor air.
ENERGY STAR certified room air purifiers are 40% more energy-efficient than standard models, saving consumers about 230 kWh/year and $25 annually on utility bills. These savings could add up to $200 over its lifetime!
Current Specification Effective Date: July 1, 2004
The ENERGY STAR specification for room air purifiers measures energy efficiency by using a Clean Air Delivery Rate-to-Watt ratio. Clean Air Delivery Rate (CADR) is a measure of the amount of contaminant-free air delivered by the room air purifier. However, the US EPA does not endorse any manufacturer claims of healthier indoor air from the use of this product.
