1.活性碳网：活性炭是一种黑色无定形粒状物或细微粉末。在空气净化器产品中，一般以颗粒状的形式存在。活性炭粒有很大的表面积，全身都遍布有丰富的微孔，其化学特性决定了其拥有较强的吸附能力，并且可以与气体进行充分接触，也就是具有较大的吸附容量，可以轻松吸附对苯、甲苯、二甲苯和四氯化碳等有害气体。当这些气体被微孔吸附后，则起到净化作用。 Activated carbon is a black amorphous particle or fine powder. In the product of air purifier, it usually exists in granular form. Activated carbon particles have a large surface area, the whole body all around is rich in pores, its chemical properties determines its strong adsorption ability, and can fully contact with the gas, which has a larger adsorption capacity, can be easily adsorbed on the harmful gas such as benzene, toluene, xylene and carbon tetrachloride. When these gases are adsorbed by micropores, they are purified. 2.HEPA网：在过滤效果方面，对直径为0.3微米的颗粒物有效去除率可以达到99.74%以上，而像吸烟环境中产生的烟雾颗粒，大多数都在0.5微米左右，这一类物质，也可以很好的过滤，因此总体说来，hepa过滤层对pm2.5过滤有着不错的效果。而在实际使用中，为了增加进风的接触面积，在市面上很多在售的空气净化器产品中，很多都采用了褶皱设计，以此来增加过滤效果。 2. HEPA network: in terms of filtering effect, to 0.3 microns in diameter particle removal efficiency can reach above 99.74%, effective and smoke particles like smoking environment, most are about 0.5 microns, this kind of material, can be very good filtering, so in general, HEPA filter layer has a good effect on pm2.5 filtering. In actual use, in order to increase the contact area of the wind, many of the air purifiers sold in the market have been designed to increase the filter effect. 3.光触媒网：光触媒在光的作用下能将甲醛、苯、甲苯、二甲苯、氨、TVOC等有害有机物、污染物、臭气、细菌等氧化分解成无害的CO2和H2O，产品具有高效广谱的消毒性能，有效控制细菌、病毒的交叉感染达到控制细菌繁殖和净化空气的目的。该产品本身不发生变化和损耗只提供一个反应场所，具有时间持久、持续作用、安全、无毒的优点，不产生二次污染，是国际公认的绿色环保无污染的产品。 3. Photocatalytic net: light catalyst under the action of light to formaldehyde, benzene, toluene, xylene, ammonia, TVOC and other harmful organisms, pollutants, odor and bacteria oxidation decomposition into harmless CO2 and H2O, the product has high efficient broad-spectrum sterilization performance, effectively control the cross infection of bacteria, viruses, achieve the goal of control bacteria breed, and purify air. The product itself does not change and loss only provides a place for the response, has the time lasting, continuous function, the advantages of safe, non-toxic, does not produce secondary pollution, is internationally recognized as green pollution-free products.
