长春良心老年公寓

Many of my friends are afraid of PM2.5, determined to buy it in the purifier, committed to purchasing. Indeed, the market is different prices, different types of purifiers are indeed quite a lot, how can we buy a good purifier? In fact, there are some "hard indicators" or very worthy of reference. Come along with Xiao Bian and get to know it!

市场上也有不少可供选择的空气净化设备，但很多人还是保持观望的态度，有的在选购时也有很多顾虑和疑问。大家担心空气净化器是否真的能滤净污染物，尤其是让大家谈虎色变的PM2.5；还有人很担心空气净化器一旦使用起来，要付很高的电费；还有担心在使用上很麻烦、不好操控。

The market also has a lot of choice of air purification equipment, but many people still maintain a wait-and-see attitude, and some in the purchase also has many concerns and questions. We worry about air purifiers really can filter pollutants, especially let everyone scared of PM2.5; and people are worried about the air purifier once used, to pay high electricity; there is also concern that in the use of very troublesome, not good control.

什么是空气净化设备

What is air cleaning 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 purification device and air purifier, air purifier, air purifier, purifier, filter name, refers to the adsorption, decomposition or transformation of various air pollutants (including PM2.5, dust, pollen, smell, formaldehyde, decoration pollution, bacteria, allergens, etc.) can improve indoor air quality, improve the living working conditions, improve air cleanliness, enhance physical and mental health products. Mainly divided into household, commercial, industrial, 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。

Commonly used air purifier air purification technologies are: photocatalyst, activated carbon, electrostatic dust collection, HEPA efficient filtration, negative ion generator. The existing air purifiers are mostly composite type, that is, a variety of purification technologies and materials are adopted simultaneously.

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 air purifier's name, type and function are different, and consumers have a lot of questions about the uneven quality of products, the confusion of prices, the false propaganda and the lack of standard. With these concerns, let us share some important ways to evaluate the quality of air cleaning equipment.

主要评价指标

Main evaluation index

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 strength of the air purifier is mainly determined by the applicable area and the amount of clean air (CADR: the amount of clean air supplied). The purification capacity of other pollutants should be combined with the applicable area. That is to say, the more space we can filter 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。

Filtration performance refers to the ability to filter suspended particulates in air (e.g., PM2.5), and whether chemical gases such as formaldehyde, benzene, or TVOC can be filtered out...... Etc.. The more kinds of pollutants that can be filtered, the higher the rate of filtration, the better.

3第三方独立单位认证检测

3, third party independent unit certification test

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。

Product performance claims (e.g. filter performance, clean air volume, energy efficiency ratio) are certified by third independent units.

4滤网使用寿命

4 filter service 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。

In addition to the efficiency of filtration, the filter also considers the service life. Although some screens have high filtration efficiency, they have high resistance, low energy efficiency, easy plugging, short service life and relatively higher 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 purifier is usually used for a long time, energy efficiency ratio as an important indicator of the purification capacity and power consumption of air purifiers, worthy of 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 capacity, but it is harmful to the human body. The national mandatory safety requirements for air purifier, ozone emission, defined in 5 * 10-6% (ozone with fish).

7慎选购买渠道

7 shop purchase 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, design and price are very different, dazzling. When purchasing air purifiers, it is recommended to buy as much as possible in regular channels such as large shopping malls, electrical appliance stores, brand stores and mainstream e-commerce websites.
