Liva EAS501 M Air Sterilizer&Deodorizer 340(W) x 360(D) x 1790(H)mm 67kg 165.3m2 220V, 60Hz, 70W White / Mirror Environmentally-friendly aluminium Moving wheels can be fixed Three outlets (front, left, right side) Combined filter(prime filter, activated carbon filter and HEPA 13 filter) Sterilization modules(20 pieces of UV-LED light, 8 pieces of photo catalyst ) activated carbon filter One-button start Power reminder: LOGO light Operation: Four indicators stand for different scale of wind force Inspection : The fault indicator(Fan/UV/Filter) is on to remind customers to replace filter/sterilization modules or check fan failure 1.Three steps of filteration Medium filter: Eliminates large particles, like dust, hair, pollen, etc. Activated carbon filter: Removes harmful chemical pollutants and absorbs odor. HEPA filter (H13): Traps microscopic dust(down to 0.3 microns) Medium filter/Activated carbon filter/ HEPA filter (H13) 2.The high reactive hydroxyl radicals (-OH) is formed after the titanium dioxide(TiO2) photocatalyst is irradiated by the UV-A light. The high reactive hydroxyl radicals (-OH) initiates redox processes leading to the degradation/mineralization of adsorbed organic and inorganic compounds. Meanwhile, the reactive species will cause deleterious alterations in cellular structure, microbial inactivation and possible destruction. Polluted air(mixed with bacteria& odors)/Formation of -OH/ React with the cell wall/ Destroy the cell wall and form harmless water. 3.The functions of the high reactive hydroxyl radicals (-OH): Sterilization& Deodorization Fitted with four sterilization modules, the air flow will be sterilized and deodorized for as many as six times. LIVA air sterilizer & deodorizer uses photocatalyst(Tio2) and UV-A irradiation to sterilize the pathogenic microorganisms, harmful chemical gases and dust(pm2.5). With the irradiation of UV-A, Tio2 will form hydroxyl radical which is highly reactive and will degrade the pollutants & microorganisms into Co2 and H2o.There are 4 sets of sterilization module in each machine, and� the route of module is ingeniously designed enabling the pollutants & microorganisms to be sterilized for 6 times. That is why LIVA air sterilizer can achieve more than 98% sterilization rate, which is much higher than other companies' products.
