Activated carbon filter: deodorize and remove harmful gases from air Ion discharger: charges particulates negatively, which will be adsorbed to the electro-positive dust collector (no replacement cost, easy to clean, and powerful dust-collecting ability/2 settings: purification – sterilization ozone is generated in the sterilization mode) Dust collector: collects particulates, and kills bacteria with high voltage electricity Nano TiO2 photocatalyst nickel media filter: generates perhydrol (H2O2) and hydroxyl (OH) under the irradiation of UV light, sterilizes, and decomposes harmful compounds (3D nano structure: 20 times more contact area than ordinary photocatalyst filters, washable filter) Ultraviolet (UV) germicidal lamp: activates photocatalytic oxidation (PCO), sterilizes air (recommended to be replaced every 15,000 hours) Negative ion generator: diffuses negative ions into the flow of clean air (ion density: more than 100,000/cc, gives you a living place abundant in negative ions)
