ENERGY STAR is a government-backed program helping businesses and individuals protect the environment through superior energy efficiency. Over the past 10 years, Energy Star has emerged as a means for consumers to identify products that are rated for high performance and low energy consumption.

A new category of Energy Star certified appliances is Air Purifiers. Holmes® and Bionaire® have a few air cleaners that have obtained Energy Star certification. To qualify-air cleaners must achieve a high CADR (clean air delivery rate) to watts consumed ratio.
