Buy ENERGY STAR® to save you money!

An ENERGY STAR certified room air purifier (also known as a “room air cleaner”) uses 40% 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.

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.
