What should I look for in an ENERGY STAR certified room air purifier?


When buying a room air purifier, request an ENERGY STAR certified model to ensure you are purchasing an energy-efficient product. In addition to reducing greenhouse gas emissions, choosing an ENERGY STAR certified room air purifier over a standard model can save you $230 in energy costs over the life of the product.

Check your room size.

Be sure to consider the square footage of the room where you will place the room air purifier. Larger models use more energy, so choose a model that is sized appropriately to fit your room.


Consider placement.

While many room air purifiers are designed to sit on the floor, tabletop models and wall-mounting designs are also available. Regardless of configuration, it is important to read the accompanying product manual for instructions on where to place your room air purifier to achieve optimum performance.

Understand Clean Air Delivery Rates.

Clean Air Delivery Rate (CADR) 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.
