NOVELTY - The utility model claims an air purifier and air purifying filter core thereof, wherein the air purifying filter core comprises a dust filter layer, nano-silver ion antibacterial net, a graphene filter layer and a graphene modified active carbon filter layer. The dust filtering layer can effectively prevent hair, paper scrap, dust and so particulate matter. nano-silver ion antibacterial net can kill multiple bacteria in several minutes, using multiple antibacterial mechanism, effective antibacterial, with long-acting antibacterial function. Graphene filter layer can effectively remove the respirable particulate matter oil smoke, dust, pollen grain diameter is more than 0.3 microns of suspended particles, filtering effect can reach more than 99 %. graphene modified active carbon filter layer has high-efficiency adsorption performance, removing volatile organic compound such as formaldehyde, toluene and so on. The utility model is capable of forming multiple barrier to dust, virus, bacteria, volatile organic compound and so on; the purifying effect of the air is more complete.
