| 通过HEPA高效过滤网结合活性炭板吸收颗粒物和甲醛。HEPA(High
efficiency particulate air
Filter)，中文意思为高效空气过滤器，达到HEPA标准的过滤网，对于0.3微米的有效率达到99.998%，HEPA网的特点是空气可以通过，但细小的微粒却无法通过
。 The particles and formaldehyde are absorbed by HEPA high efficiency filter screen combined with active carbon plate. HEPA (high efficiency particulate air filter), which means high efficiency air filter in Chinese, is a HEPA standard filter with an effective rate of 99.998% for 0.3 μ M. HEPA network is characterized by that air can pass through, but small particles can not. 有些厂商还会加入杀菌布、初效过滤网、负离子、冷触媒、紫外灯等。后面这些功能主要是为了辅助净化，主力还是在HEPA滤网和活性炭上。目前90%厂家都选择了这种净化方式。 Some manufacturers will also add bactericidal cloth, primary filter screen, anion, cold catalyst, UV lamp, etc. The latter functions are mainly for auxiliary purification, mainly on HEPA filter screen and activated carbon. At present, 90% of manufacturers have chosen this purification method. 优点：技术成熟稳定、净化效率高、甲醛和颗粒物CADR值高。 Advantages: mature and stable technology, high purification efficiency, high Cadr value of formaldehyde and particulate matter. 缺点：滤网需要定期更换、风阻可能产生噪音。 Disadvantages: the filter screen needs to be replaced regularly, and the wind resistance may generate noise. |
