Car Purifier Purifier for car or car air purifiers, usually generated by a high voltage circuit negative ion generator, wind fans, air filters and other system components. It of work principle following: machine within of Breeze fan (and said ventilation machine) makes indoor air cycle flow, pollution of air through machine within of air filter device (two times filter) Hou will various pollutants clear or adsorption, then after loaded in air outlet of anion generator (work Shi negative ion generator in the of high pressure produced DC negative high pressure), will air constantly ionization, produced large anion, was breeze fan sent out, formed anion air, reached clean, and purification air of purpose
