Applicable space 135m3 Voltage & power 220-240v 50hz 71-76w Unit dimension 409*210*526mm Filtrating system: 1.Pre-filter Eliminates large particulates like pet¡¯s hair, body scurf and big dust. 2. Activated carbon filter With activated carbon particles in honeycomb form, very adsorbable and can quickly deodorize by adsorbing airborne odorous molecules. 3.High efficiency particulate air (hepa) filter Filtrates over 99% of airborne particulates down to 0.3 micron Removes fine particulates such as dust, pollen, virus and bacteria efficiently. 4.Ultraviolet (uv) germicidal lamp+ nano tio2 photocatalyst nickel media filter Generates perhydrol (h2o2) and hydroxyl (oh) to sterilizes the air, kills and inhibits bacteria, mildew and decomposes toxic chemicals. Tio2 material; 3d nano structure : 20 times more contact area than ordinary photocatalyst filters. 5.Negative ion generator Ion density: >500, 000/cc; as if you are living in the forest, at the seaside or near a waterfall. 6. Wide-angled remote control+ manual control 7.Lcd panel for easy control 8.Children lock to prevent children's misoperation Export carton: 460*250*582mm G.W.:8.50kg N.W.: 7.30kg
