It is not fine dust. It is virus, germs, & harmful gases(sick house syndrome) problem changing air quality, the innovative air sterilizing deodorizer, Puripot. Why Puripot ? Sars, Mers, COVID-19 virus pandemic from now on, a war with virus not fine dust! Dearly virus and germs to humans are so small that one cannot eliminate with HEPA filters. We have 4 types of Puripot: P series / M series / L series / F series Puripot (Personal Air Purifier and Sterilizer): P1/P1+/P1N * Deodorization: Strong deodorization by photocatalytic oxidation (PCO) of nano-porous structured titanium dioxide * Sterilization: Strong sterilization by photocatalyst honeycomb unit with hydroxyl radical to remove VOCs, bacteria and viruses * Dual Filtration: Powerful air purification with replacement-free PCO mesh unit and blue light PCO honeycomb module * Mood Lighting: Indirect mood lighting capability with internal blue LED * Natural Humidification: Natural Humidification effect with internal water * Air quality monitor: Air quality monitoring with VOC gas sensor and color indication of measured air quality * IoT Function : Mobile App based IoT service Key Functions & Benefits: * 99.9%: Airborne Germ(Bacteria), Virus, atopy causing Harmful Gases(VOC) Elimination. (VOCs, ultrafine dust, odor, Bacteria, Virus Germ, Mold, pollen, House Dust mite) * No filter change: Unlike HEPA filter requiring periodic filter change, no cumbersome change of filters, no Cost! Without collecting bad harmful matters, it eliminates by decomposition" ! * Effect: Not only residences but restaurants exposed to smells, hotels expected to be kept most fresh, hospitals trusted to stay safer than any where else benefit the most. Innovative PCO(Photo Catalytic Oxidation) Technology! * Responsible for the clean air environment in the international space station. * Fine dust, for sure, and lots of viruses and harmful gases are decomposed into water and carbon dioxide using only visible light, which is harmless to humans. Generates no Ozone or Ultraviolet(UV) light at all therefore very safe, and there is no need to change filters which makes it also an economically outstanding device. * Hydroxy Radical(OH): 30,000 degree C hot air furnace effect decomposes and removes harmful matters Air Purifier, of the World * Best seller in Amazon, Makuake and Indiegogo * CES 2020 Innovation Awards * Good Design - Ministry of Trade, Industry and Energy of Korea * KC, FCC, CE certificate Safe, Trust and Use * 99% sterilization - KATR * VOC decompose test report - KTR * Airborne Germ Reduction Result - KTL
