Section home air purifier, triple filter layer 7 filtering purification, PM2.5 unique display, with a front early effect filters, HEPA high efficiency filtration, activated carbon filtration, molecular sieve adsorption purification, photocatalyst purification, UV sterilization purification , negative ion purification. There are four color options green and blue powder, fourth gear wind speed, ABS material, NW 7.5Kg. When we first look at the election of air purifier manufacturers, of course, the strength, at least in the product quality assurance and technology can give to you that, in the Pearl River Delta or Yangtze River generally have these high technology electronics industry where it you have to visit, again product selection you first set a good positioning, in general is low or high, you want to do is see what kind, for which customers, so product selection will not say more than just the price, low price you can not necessarily sell well. . . Like air purifiers usually targeted at high-end customers, they will be aware of this need, it would not do much publicity. First layer: electrostatic precipitator filtration can filter smaller than the cells of dust, smoke and bacteria, prevent lung disease, lung cancer and liver cancer and other diseases. The air is the most harmful to human dust less than 2.5 microns, which is likely to penetrate cells and into the bloodstream. Second layer: formaldehyde filtration efficiency to formaldehyde unique complex filter can remove air contaminants, particularly formaldehyde and other harmful gases. Unique complex and efficient to use a granular activated carbon filter formaldehyde special treatment, cleans gases and other harmful gases containing formaldehyde. In addition, the filter can effectively remove allergens and bacteria. Third layer: granular activated carbon filter Formaldehyde is widely used in building materials, is a colorless gas with a strong pungent odor, is highly carcinogenic. Granular activated carbon formaldehyde removal efficiency of 96.2%.
