Room Air Cleaners

ENERGY STAR® certified room air cleaners are 40 percent more efficient than non-certified models — saving you money and energy. Room air cleaners (also called “room air purifiers”) remove fine particles such as dust, pollen, smoke, and pet dander from indoor air. Additionally, they help alleviate household odors that come from sources such as pets, cooking, and smoke. 

Room air cleaners have many benefits, but some require lots of energy. A typical room air cleaner that operates continuously uses approximately 60 percent more electricity than a new refrigerator.

Why Choose an ENERGY STAR Certified Room Air Cleaner?

Markedly more efficient than non-certified models, ENERGY STAR certified room air cleaners can save you up to $30 annually on energy costs. That could add up to more than $250 over the lifetime of the air cleaner.

How to Find the Most Efficient Room Air Cleaners

The efficiency of a room air cleaner is measured by its Clean Air Delivery Rate-to-Watt (CADR/Watt) ratio. The Clean Air Delivery Rate (CADR) specifies the volume of filtered air delivered by an air cleaner over a standard period of time. The CADR/Watt ratio measures how much energy is used to filter that air. A higher CADR/Watt ratio indicates a more efficient room air cleaner, because more air is filtered for every watt of electricity used.
