Abstract
An air purifier has an air blower and a rotating brush, the brush having long flexible bristles made of a material that is capable of developing negative triboelectric charge. During a portion of the rotation cycle, the bristles move across a surface that can accumulate a positive charge. This causes the bristle to charge negatively. Air impurities are attracted to the negatively charged bristles and are discharged into a collecting bin.
