空气净化设备怎么挑？

How to select air purification equipment?

空气净化装置又称空气净化器、空气清洁器、空气清新机、净化器、过滤器等名称，是指能够吸附、分解或转化各种空气污染物（一般包括PM2.5、粉尘、花粉、异味、甲醛之类的装修污染、细菌、过敏原等），可以提高室内空气质量，改善居住、办公条件，有效提高空气清洁度，增进身心健康的产品。主要分为家用、商用、工业、楼宇。

Air purifier, also known as air purifier, air cleaner, air cleaner, purifier, filter and other names, refers to the adsorption, decomposition or transformation of various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), can improve indoor air Quality, improve living and office conditions, effectively improve air cleanliness, enhance physical and mental health products. They are mainly divided into household, commercial, industrial and building.

空气净化器中常用的空气净化技术有：光触媒、活性炭、静电集尘、HEPA高效过滤、负离子发生器等。现有的空气净化器多为复合型，即同时采用了多种净化技术和材料介质。

The commonly used air purification technologies in air purifiers include photocatalyst, activated carbon, electrostatic dust collection, HEPA high efficiency filtration, negative ion generator, etc. The existing air purifiers are mostly composite, that is, a variety of purification technologies and material media are used at the same time.

市场上空气净化器的名称、种类、功能不尽相同，消费者对于产品质量参差不齐、价格混乱、虚假宣传以及标准缺失等产生了很多质疑。带着这些大家担心的问题，让我们一起来了解一些重要的评价空气净化设备质量的方法。

The names, types and functions of air purifiers on the market are not the same. Consumers have many doubts about the uneven quality of products, price chaos, false publicity and lack of standards. With these concerns in mind, let's look at some important ways to evaluate the quality of air purification equipment.

主要评价指标

Main evaluation indicators

1洁净空气量（CADR）

1 clean air volume (CADR)

空气净化器净化能力的强弱，主要是由适用面积和颗粒物洁净空气量（CADR：提供的洁净空气的量）决定的。对其它污染物的净化能力，应和适用面积相结合。也就是说，单位时间内，能滤净的空间越大，则效果越好。

The purifying capacity of the air purifier is mainly determined by the applicable area and the amount of particulate clean air (CADR: the amount of clean air provided). The purification capacity of other pollutants should be combined with the applicable area. That is to say, the larger the space that can be filtered in unit time, the better the effect.

2滤净性能

2 filtration performance

滤净性能是指可滤净空气中悬浮微粒的效能（例如PM2.5），以及是否可滤除家中的化学性气体如甲醛、苯系物、TVOC……等。能滤净的污染物种类越多、滤净率越高，则越好。

Filtering performance refers to the ability to filter suspended particulates in the air (e.g. PM2.5), and whether chemical gases such as formaldehyde, benzene series, TVOC can be removed from the home. Wait. The more pollutants can be filtered and the higher the filtration rate, the better.

3第三方独立单位认证检测

3 third party independent unit certification testing

产品效能宣称（例如：滤净性能、洁净空气量、能效比等）是否经第三方独立单位认证。

Whether the product performance claims (e.g. filter performance, clean air volume, energy efficiency ratio, etc.) have been certified by a third party independent entity.

4滤网使用寿命

4 filter life

滤网除了滤净的效能以外，还要考虑使用寿命这个因素。一些滤网虽然具有较高的过滤效率，但是阻力大，能效比较低，而且很容易堵塞，使用寿命较短，相对的后续维护的成本较高。

Besides the efficiency of filtering net, the factor of service life should also be considered. Although some filters have high filtration efficiency, they have high resistance, low energy efficiency, easy blockage, short service life and relatively high cost of follow-up maintenance.

5能效比和能效等级

5 energy efficiency ratio and energy efficiency grade

空气净化器通常是长期连续使用的，能效比作为衡量空气净化器净化能力与电力消耗的重要指标，值得大家关注。

Air purifiers are usually used continuously for a long time. As an important index to measure the purifying capacity and power consumption of air purifiers, energy efficiency ratio deserves our attention.

6臭氧释放量

6 ozone release

臭氧作为强氧化剂具有一定的净化能力，但对人体是有伤害的。国家对空气净化器臭氧释放量有强制性安全要求，限定在≤5×10-6%（臭氧具有鱼腥味）。

Ozone as a strong oxidant has a certain purification ability, but it is harmful to the human body. The state has mandatory safety requirements for ozone emission from air purifiers, which are limited to <5 *10-6% (ozone has fishy smell).

7慎选购买渠道

7 be careful about buying channels.

空气净化器品牌、功能、性能、外观设计和价格都有很大的区别，让人眼花缭乱。建议购买空气净化器时，建议尽量在大型商场、电器商店、品牌专卖店和主流电子商务网站等正规渠道购买。

Air purifier brand, function, performance, appearance design and price are very different, dazzling. When purchasing air purifiers, it is recommended to purchase air purifiers in large shopping malls, electrical appliances stores, brand stores and mainstream e-commerce websites.
