The purifiers are Energy Star products so you won't have to worry about high energy bills. Ten minutes after the air in the room has been cleaned, the purifier shuts off all functions except air pollution detection. The high performance devices have three stages of filtering including the pre-filter that removes larger debris like pet dander, dust,and human hair. The HEPA filter, the final stage of the filtering process removes smaller particles including smoke and mold spores.

In case you were wondering, the hole in the device is more than a design statement. It actually serves as an air pollution indicator and a mood lamp.Equipped with five-speeds the Conway purifiers can purify the air in the room up to 300 square feet.
