Buy ENERGY STAR® to save you money!

An ENERGY STAR certified room air purifier (also known as a “room air cleaner”) uses 60% less energy, on average, than a standard model. Saving energy saves money and reduces your carbon footprint.

Key features

  • Those with a clock or remote control consume fewer than two watts while in standby mode.

Start your research using the ENERGY STAR Product Finder tool to find and compare certified air purifiers (Note: you will be redirected to the US ENERGY STAR website.)

Helpful tips

  • Buy the right size! Larger models use more energy, so purchase one that is appropriately sized for the room.
  • Place the room air cleaner according to manufacturer’s recommendations. Tabletop and wall-mounted models in particular usually have special instructions for optimum efficiency.
  • Look for the “Clean Air Delivery Rate” (CADR). This measures how quickly a unit delivers filtered air and can be used to measure the performance of a room air purifier. The higher the CADR, the more quickly the room air purifier filters the air.


All ENERGY STAR certified products are tested to meet strict efficiency specifications and are certified by an independent third party. They perform the same as or better than standard products without compromising performance in any way.
