Does Neotec air purifier have Black Wall effect?
Neotec air purifiers use the stainless steel needle point that is corrosion free. And the collector plate is made of highly condusive materials that will attract ionized particle. The ionized particle will only attach to the metal collection surface not the low condusive materials around the machine, cover or on the wall. So The Black Wall or Gray Wall effect will not occur on our air purifiers.
