Voltage: AC220V Power: 30-65W weight: 15kg Anion Density:1*106pcs/cm3 Ozone density:100-300m3/h Noise: 35dB-50dB Size: 450*350*850 mm Area: 70-100m2 Usage: office, household Package: 1 pc/carton Air purify: 1. Strongly HEPA filter: concentratedly and effectively filter many kinds of mote in air and can clearly die off 99.97% suspended grain to the 0.3 micron 2. Nanometer light-accelerant air purification: use advanced Tio2 light accelerant, faster and more completely decompose harmful volatile organic compounds inside the house, such as formaldehyde, ammonia, benzene, TVOC, deodorize unpleasant smells of cigarette smoke, alcohol, effectively kill suspended bacteria and viruses, and protect passengers from cross infection 3. Reformed active carbon filter: completely decompose harmful volatile organic compounds inside the house, such as formaldehyde, ammonia, benzene, TVOC, deodorize unpleasant smells. 4. Negative oxygen ion air purification: produced oxygen ion creates the atmosphere of forest which can ease the tension, and die off the harmful substances in air as well. 5. Intellectual control system: adopt Micro-computer control system, can detect and clear up the harmful volatile organic compounds automatically. 6. Catalytic agent purification at normal temperature: The catalytic agent applied in Shenzhou Aero Spaceship can get rid of the formaldehyde, benzene, CO, etc. efficiently.
