Hartcourt home air purifier, triple filter layer 7 filtering purification, PM2.5 unique show, with a front early effect filters, HEPA high efficiency filtration, activated carbon filtration, molecular sieve adsorption purification, purification photocatalyst, UV sterilization purification, 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. . . Buy an air purifier must first understand the relevant knowledge of the relevant knowledge of the air purifier can help you how to buy air purifiers, air purifiers on the market today, many brands of air purification are not the same, resulting in customers to buy air purifiers When cause great distress, we answer your questions one by one. First, the air cleaner main purification options? Air purifier air purification technology commonly used are: adsorption, ion technology, the negative oxygen ions, molecular complex technology, photocatalyst technology, titanium dioxide technology, HEPA efficient filtration technology, electrostatic dust collection technology, active oxygen technology; materials technology They are: photocatalyst, activated carbon, synthetic fibers, HEAP efficient materials, negative ion generator. Existing air purifier much more expensive than the complex, which simultaneously uses a variety of techniques and materials purification media. Second, what is the main air purifier purifying? a, respirable particulate matter from the outside air, including dust, smoke, pollen, PM2.5, PM10 and other suspended solids, for asthma, respiratory disease population greater impact; b, gaseous pollutants - including formaldehyde, benzene, TVOC , ammonia, nitrogen oxides, sulfur dioxide, ozone, etc.; c, microbes - including various types of common bacteria, viruses, mites corpses, dander, etc., especially the family pet is important. In short, the air purifier main function is to remove the dust particles to kill bacteria and viruses, removing formaldehyde BTEX. Air purifiers and many additional features, such as increased humidity, increased anion, increase oxygen, mainly to see the child lock individual needs, not the main consideration. And when to buy air purifiers, can not fail to consider post-maintenance costs, periodic replacement of filters and additives, the replacement of wearing parts, and warranty service. We recommend that you choose an air purifier In short, the main function of air purifiers to remove dust particles that kill bacteria and viruses, removing formaldehyde BTEX.
