Photocatalytic Oxidation (PCO) technolgy
The HEPA / UV air purifiers have been on the market for a while, but there have also been some recent advances made in air purification technologies as of late. Many air purifier manufacturers are now utilizing Photocatalytic Oxidation (PCO) technology as a way of removing toxins from the air.
