This is the air cleaner that removes air pollutants without costly filters. It emits billions of harmless electrons that attach to air impurities and convert them to negatively charged ions, causing the invisible pollutants to gravitate and bond to the positively charged collection tube (larger dust particles will fall to the ground).
