No maintenance, no filter costs The 905A negative oxygen ion air purifier is a device that uses a negative oxygen ion generator to purify the air. The core principle of the negative oxygen ion air purifier is the release of negatively charged ions (primarily negative oxygen ions), which combine with positively charged particles in the air (such as PM2.5, dust, pollen, and bacteria) to neutralize their charge and clump together into larger particles. Due to their increased weight, the particles sink to the ground or the surface of objects, clearing the breathing space and ultimately purifying the air.
