1、“HEPA高效过滤技术”滤净效能好
HEPA是一种国际公认最好的高效滤材，HEPA过滤器由一叠连续前后折叠的亚玻璃纤维膜构成（空气净化机中常用PP，聚丙烯材质），形成波浪状垫片用来放置和支撑过滤界质。HEPA高效率微粒滤网的滤净效能与其表面积成正比。目前HEPA空气净化装置的HEPA高效率微粒滤网均是多层折叠，展开后面积比折叠时增加十几倍到几十倍，滤净效能十分出众。
HEPA is an internationally recognized best high efficiency filter material, HEPA filter is composed of a stack of continuous before and after folding sub-glass fiber membrane (commonly used in air purifier PP, polypropylene material), the formation of a wavy gasket used to place and support the filtration boundary material.The filter efficiency of HEPA particulate filter is proportional to its surface area.At present, HEPA air purification device HEPA high efficiency particulate filter is multi-layer folding, after the expansion of the area than folding increased by ten times to dozens of times, filtration efficiency is very outstanding.
净化原理：微粒惯性原理和扩散原理。
Purification principle: particle inertia principle and diffusion principle.
HEPA净化技术优点：
过滤颗粒物的效果非常明显！对微粒的捕捉能力较强，孔径微小，吸附容量大，净化效率高，并具备吸水性，针对0.3微米的粒子净化率为99.97%。如果用它过滤香烟烟雾，那么过滤的效果几乎可以达到100%。2.5μm以上的颗粒，仅需F8的就可以过滤效果达到99%以上了。
The effect of filtering particulate matter is very obvious!It has strong ability to capture particles, small pore size, large adsorption capacity, high purification efficiency, and has water absorption, and the purification rate for 0.3 micron particles is 99.97%.If it is used to filter cigarette smoke, it is almost 100% effective.For particles above 2.5μm, only F8 can filter more than 99%.
HEPA净化技术缺点：
我国尘土比较严重，HEPA的使用寿命可能相对缩短，也就意味着HEPA过滤器需要经常更换以及使用成本高。目前，空气净化行业中的风速普遍不是在HEPA的合适风速下工作，洁净室这类要求高的场所保证HEPA的净化效率在0.3-0.5m/s左右，实际使用中的风速都是远高于这个值。
China's dust is more serious, the service life of HEPA may be relatively shortened, which means that HEPA filters need to be replaced often and the use of high cost.At present, the wind speed in the air purification industry is generally not the right wind speed in the work of HEPA, clean room such high requirements of the place to ensure that the purification efficiency of HEPA in 0.3-0.5m/s, the actual use of wind speed is much higher than this value.
2、“静电集尘技术”，无耗材除尘
静电集尘技术是利用高压静电吸附的原理，将空气中的污染物过滤，同样作为基础净化技术，被广泛应用于室内空气净化器上。
Electrostatic dust collection technology is the use of high voltage electrostatic adsorption principle, the air pollutants in the filter, also as a basic purification technology, is widely used in indoor air purifiers.
净化原理：高压强电场的作用，颗粒物吸附在负极板或者正极板，异种电荷相互吸引。
Purification principle: the effect of high voltage and strong electric field, particles adsorbed on the negative plate or positive plate, dissimilar charges attract each other.
静电集尘技术优点：
高效去除空气中的微粒污染物，如灰尘、煤烟、花粉、香烟味和厨房油烟等，同时还可有效吸附空气中的气态污染物及滤除空气中的致病微小生物，无耗材，清洗可重复使用，真正的环保；
Efficient removal of particulate pollutants in the air, such as dust, soot, pollen, cigarette smell and kitchen lampblack, but also can effectively adsorb gaseous pollutants in the air and filter out pathogenic small organisms in the air, no supplies, cleaning can be reused, real environmental protection;
静电集尘技术缺点：
容易产生臭氧，而且只对颗粒物等大粒子气体有效果，主要用于除尘，而对于去除甲醛、苯系物、TVOC等装饰装修造成的化学污染几乎没有效果，相当于初中效过滤网，净化本质，还属于物理净化，有害物质并没有被化学分解。
It is easy to produce ozone, and only has an effect on large particle gases such as particulate matter, which is mainly used for dust removal. It has almost no effect on the removal of chemical pollution caused by formaldehyde, benzene series, TVOC and other decoration. It is equivalent to the filter screen of junior high school effect, which is purification essence, and also belongs to physical purification, and harmful substances are not decomposed chemically.
3、“活性炭吸附技术”，吸附能力很强
活性炭分为椰壳类、果壳类和煤炭类三种，吸附能力以椰壳类活性炭最强。
Activated carbon is divided into coconut shell, nut shell and coal three kinds, the adsorption capacity of coconut shell activated carbon is the strongest.
净化原理：活性炭多孔结构，比表面积大，能吸附小颗粒物质。
Purification principle: activated carbon porous structure, large specific surface area, can absorb small particles
活性炭优点：对所有的空气污染物都具有净化作用。吸附能力很强，能够有效吸附室内空气中的有害物质（诸如粉尘、微粒、游离分子、细菌等）。
Advantages of activated carbon: all air pollutants have a purification effect.Strong adsorption capacity, can effectively absorb harmful substances in indoor air (such as dust, particles, free molecules, bacteria, etc.).
活性炭缺点：活性炭只是属于物理过滤，污染物并没有被消除，只能暂时吸附，并且随温度、风速升高，所吸附的污染物就有可能游离出来，所以要经常更换过滤材料，避免吸附饱和。
Activated carbon disadvantages: activated carbon is just a physical filtration, pollutants have not been eliminated, can only be temporarily adsorbed, and with the temperature, wind speed rise, the adsorption of pollutants may be free, so often replace the filter material, avoid adsorption saturation.
4、负离子技术，烟雾沉降、补充“空气维生素”
通过负离子发生器，产生大量的负离子，也叫负氧离子，具有镇静、催眠、镇痛、增食欲、降血压等功能。雷雨过后，人们感到心情舒畅，就是空气的负离子增多的缘故。空气负离子能还原来自大气的污染物质、氮氧化物、香烟等产生的活性氧（氧自由基）、减少过多活性氧对人体的危害；中和带正电的空气飘尘无电荷后沉降，使空气得到净化。
Through the negative ion generator, produce a large number of negative ions, also called negative oxygen ions, with sedation, hypnosis, analgesia, appetite, drop blood pressure and other functions.The increase in negative ions in the air is the reason why people feel good after a thunderstorm.Air anion can reduce the reactive oxygen species (oxygen free radicals) produced by pollutants from the atmosphere, nitrogen oxides and cigarettes, and reduce the harm of excessive reactive oxygen species to human body.Neutralize positively charged air drift dust without charge after settling, so that the air is purified.
净化原理：正负电荷中和，以及负离子的还原作用。
Purification principle: positive and negative charge neutralization, as well as reduction of negative ions.
负离子优点：
对二手烟等颗粒物沉降作用明显，因此一程度上能除烟味，主要是因为空气中的烟雾颗粒物减少，烟味的颗粒物沉降到地面，更多的是属于物理净化。对人体有抗氧化、抗衰来、增强人体免疫力、增强自愈能力的作用，能有效增强血液携氧能力20%左右并有效促进人体新陈代谢改善睡眠，对杀菌有一定的作用。
The sedimentation effect of second-hand smoke and other particles is obvious, so to some extent, it can remove the smell of smoke, mainly because the smoke particles in the air are reduced, the smoke particles settle to the ground, more belongs to the physical purification.It has the function of anti-oxidation, anti-aging, enhancing human immunity and self-healing ability. It can effectively enhance the oxygen carrying capacity of blood by about 20% and effectively promote human metabolism and improve sleep. It has a certain effect on sterilization.
负离子缺点：
负氧离子起净化作用过程中主要是“物理净化”，空气中的污染物被转移到地上了；负氧离子在空气中寿命很短，所以需要持续释放；对因装饰装修造成的甲醛苯系物等污染净化效果则很一般，所以需要您区别选择。
Negative oxygen ions play a role in the process of purification is mainly "physical purification", the pollutants in the air are transferred to the ground;Negative oxygen ions have a short life in the air, so they need to be released continuously.For the decoration caused by formaldehyde benzene series pollution purification effect is very general, so you need to choose.
5、臭氧，杀菌除味迅速彻底
活性氧技术是基于臭氧发生器的应用，也是种基础净化技术，凡是离子发生器基本都能释放出一定浓度的臭氧，也被广泛应用于绝大多数的空气净化器中。
Reactive oxygen technology is based on the application of ozone generator, is also a basic purification technology, all ion generator can release a certain concentration of ozone, is also widely used in the vast majority of air purifiers.
在使用臭氧杀菌的净化器时，务必要严格注意臭氧的产生率是否符合国家标准（国家卫生部规定的臭氧安全浓度为0.1ppm，工业卫生标准为0.15ppm），同时使用臭氧发生器净化室内空气时人员必须离开，消毒完毕开窗通风半小时以上。
In the use of ozone sterilization of the purifier, be sure to pay strict attention to the ozone production rate is in line with the national standard (the Ministry of Health prescribed ozone safety concentration of 0.1ppm, industrial hygiene standards for 0.15ppm), at the same time the use of ozone generator to purify indoor air personnel must leave, disinfection completed more than half an hour window ventilation.
净化原理：臭氧的强氧化性，可以氧化有机物、臭味分子，氧化微生物的功能结构使失活。
Purification principle: strong oxidation of ozone, can oxidize organic matter, odor molecules, oxidize the functional structure of microorganisms so that inactivation.
臭氧净化的优点：
臭氧对细菌的灭活反应很迅速、杀菌的彻底性也是不容怀疑的，合理使用时是国际公认的最环保最彻底有效的净化方式。当其浓度达到一定值后，杀菌消毒甚至可以瞬间完成。
Ozone on the bacterial inactivation reaction is very rapid, sterilization thornness is not doubt, reasonable use is the international recognized the most environmental protection and the most thorough and effective way of purification.When its concentration reaches a certain value, sterilization can even be completed instantly.
臭氧净化的缺点：
超标的臭氧对人体健康有严重危害！高浓度的臭氧，会造成咽喉肿痛、胸闷咳嗽、引发支气管炎和肺气肿、造成神经中毒、破坏人体的免疫机能等。由于臭氧有强烈刺激性，人们在感到不适时早已避开，因此在使用过程中一般不会出现中毒现象。
Excessive ozone is a serious hazard to human health!High concentration of ozone, will cause sore throat, chest tightness cough, cause bronchitis and emphysema, cause nerve poisoning, destroy the immune function of the human body.Because ozone has strong irritation, people have long avoided when they feel uncomfortable, so in the process of use generally will not appear toxic phenomenon.
6、“光触媒催化分解技术”有紫外线才能发挥作用
光催化技术，是一种利用新型的复合纳米高科技功能材料的技术，就是指光催化反应。
Photocatalytic technology, is a use of new composite nanometer high-tech functional materials technology, refers to the photocatalytic reaction.
光催化净化原理：在光源照射下，光触媒能够利用特定波长光源的能量产生催化作用(氧化还原反应)，使周围的氧气及水分子激发成具高活性的自由基，这些自由基，也有说法叫“光等离子体”，几乎可分解所有对人体或环境有害的有机物质及部分无机物质。（光触媒(Photocatalyst)，也称为光催化剂(Light catalyst)，是一类以二氧化钛（TiO2）为代表的，在光的照射下自身不起变化，却可以促进化学反应，具有催化功能的半导体材料的总称。）
Photocatalytic purification principle: under the light irradiation, the light catalyst catalyzed to be able use energy from the specific wavelength light source (REDOX reaction), the surrounding of inspired oxygen and water molecules into a highly reactive free radicals, these free radicals, also have is called "plasma" light, almost all or harmful to the environment to the human body can be decomposed organic material and part of inorganic substances.Photocatalyst, also known as Light catalyst, is a kind of titanium dioxide (TiO2) as a representative, under the irradiation of Light itself can not change, but can promote chemical reaction, has the catalytic function of semiconductor materials.
光催化优点：光催化技术具有广谱性的实用性效果，净化效率较高。
Photocatalytic advantages: Photocatalytic technology has a wide spectrum of practical effect, high purification efficiency.
光催化缺点：光触媒必须在紫外线的照射下才能发挥作用。这意味着，一是必须另外加上紫外灯发射紫外线（波长在254nm或者365nm），但是过多的紫外线对人体有伤害，所以要避免紫外线灯裸露；二是，光触媒必须能和紫外线接触，所以颗粒物多的环境，光触媒是会“冬眠”的。
Disadvantages of photocatalysis: photocatalyst must be in the ultraviolet radiation to play a role.This means that, first, the ultraviolet lamp must be added to emit ultraviolet radiation (wavelength in 254nm or 365nm), but too much ultraviolet radiation is harmful to the human body, so the ultraviolet lamp should be avoided;Second, the photocatalyst must be able to contact with ultraviolet light, so the environment with more particles, the photocatalyst will "hibernate".
7、“分子络合技术”治理室内装修污染效果明显
分子络合技术是目前能够真正有效彻底去除室内装修污染，尤其是化学污染的技术。该技术首先对室内装修污染甲醛、苯、氨等污染物进行收集、捕捉，再通过甲醛捕捉剂和水组成的络合分解体系，分别将甲醛和氨等气态短分子链物质，迅速络合转化为不可逆的长分子链固态物质，并分解生成氨盐，结聚、沉淀于水中清除分离，排放出清洁空气。

净化原理：这种技术利用甲醛和氨的溶水特性，将室内空气引入净化器中，将其中的有毒气体通入分子络合剂（甲醛捕捉剂）与水组成的络合分解体系，最终将室内空气中的污染物转化为不可逆的中性的大分子链固态物质，再排除相对洁净的空气，最终达到净化的作用。
Purification principle: this technique using formaldehyde and ammonia water soluble characteristic, introduces indoor air purifier, will be one of the toxic gases bubbled into molecule complexing agent (formaldehyde capture agent) and the decomposition of complex system composed of water, will eventually in the indoor air pollutants into neutral irreversible solid material, macromolecule chain again ruled out relatively clean air, eventually achieve the effect of purification.
分子络合技术优点：
属于“化学净化”，该技术对室内装饰装修所造成的甲醛、苯系物、TVOC等污染作用效果比较明显。
It belongs to "chemical purification", which has obvious effect on formaldehyde, benzene series, TVOC and other pollution caused by interior decoration.
分子络合技术缺点：
含有络离子的溶液或类似组件，需要定时更换，尤其在新居污染程度高时更换频率较高。产生新的溶液，直接排放对环境有二次污染；
Solution containing complex ions or similar components, need to be replaced regularly, especially in the new residence when the degree of pollution is high replacement frequency.Produce new solution, direct discharge of secondary pollution to the environment;
8、“低温非对称等离子体空气净化技术”超节能、超环保
低温非对称等离子体空气净化技术，目前主要通过介质阻挡放电实现，即DBD低温等离子，现在主要存在2中，一种是正高负低的DBD低温等离子，净化能力强，主要用在工业净化和无人环境净化；另一种是负高正低的DBD低温等离子，简称NBD等离子（negative ion high DBD），主要应用在人居环境，人机共存环境。

低温等离子缺点：
作为尚未普及一项新技术，目前技术成熟的厂家并不多，基于该技术的产品不多，并且存在价格上的不透明。德国碧欧、韩国SP、美国BOX，国内浙江、福建也有几家很不错。
As a new technology that has not yet been popularized, there are not many manufacturers with mature technology at present. There are not many products based on this technology, and the price is not transparent.Germany, SP, South Korea, the United States BOX, Zhejiang, Fujian also have several very good.
此处的低温等离子，指负高正低的低温等离子，即NBD类型。
简要总结：
通过一种空气净化技术就可以完美地解决所有空气污染的问题，目前是不存在的，面对不同的污染源我们需要选择最适合的空气净化技术产品，同时也要结合自己的实际情况选择合适的产品。最好是选择CCM值比较高的净化机，这样产生的耗材小，对环境污染比较小。
