Select the purifier before buying to be targeted

任何空气净化装置对污染物的净化都是有针对性的，不同原理的空气净化器技术都有一定的优势，但也相对存在一定的局限性。有专家认为，按照去除功能，目前市场上空气净化器分为物理型、化学型和离子化型。

All air purifiers are targeted for purification of pollutants. Different principles of air purifier technology have certain advantages, but there are still some limitations. Some experts believe that, according to the removal function, the air purifier in the market is divided into physical, chemical and ionized types at present.

物理型是通过过滤除去悬浮颗粒物，一般适用于去除颗粒。

The physical type is the removal of suspended particles by filtering, which is generally applicable to remove particles.

化学型是利用中和、催化和分解作用除去有害气体。

Chemical type is the use of neutralization, catalysis and decomposition to remove harmful gases.

离子化型则是采用电量放电、等离子体和紫外线除臭、杀灭细菌。

Ionization type is the use of electrical discharge, plasma and ultraviolet deodorization, killing bacteria.

家庭选购空气净化装置时，首先要确定净化目的，即净化何种污染物，如果目的是主要针对细颗粒物PM2.5，就要选择对PM2.5有效的净化器，才可降低室内雾霾污染程度。

When the family chooses air purification equipment, we must first determine the purify purpose, which is to purify the pollutants. If the aim is mainly for fine particles PM2.5, we must choose an effective purifier for PM2.5 to reduce indoor haze pollution.

室内空气中有哪些主要污染物？一般可以通过空气采样检测后加以了解和初步判定。文献资料显示，室内居住场所常见的污染因子，主要有苯、甲醛、吸烟的烟雾，烹调油烟以及细颗粒物PM2.5等。

What are the main pollutants in the indoor air? Generally, it can be understood and preliminarily judged by air sampling. The literature shows that the main pollution factors in the indoor residential areas are benzene, formaldehyde, smoked smoke, cooking oil smoke and fine particulate matter PM2.5.

购买时能效指标要注意三高一低

The index of energy efficiency should be paid attention to three high and one low.

根据国家标准化委员会发布的国家标准《空气净化器》（GB/T 18801-2015），一台真正有效的空气净化器要做到：

According to the national standard "air purifier" issued by the National Standardization Committee (GB/T 18801-2015), a truly effective air purifier should be done:

高洁净空气量：洁净空气量（CADR）是净化器的净化效果指标，CADR值越大，净化器的净化能力越强，净化效果越好。

Gao Jie clearance air volume: clean air volume (CADR) is an indicator of purifiers purification efficiency. The greater the CADR value, the stronger purifier's purification ability is, the better the purification effect is.

高累计净化量：累计净化量值越高，净化的污染物越多，滤网寿命越长。

High accumulative purification: the higher the accumulative purification value, the more pollutants to be purified, the longer the lifespan of the filter.

高能效值：高能效值越高，越省电。

High energy efficiency: the higher the high energy efficiency, the more electricity is saved.

低噪音量：仪器工作噪音一般低于50分贝属于相对安静的，选购时可以观察样机进行直观感受。

Low noise volume: the noise of the instrument is generally lower than 50 decibels, which is relatively quiet.

另外，一些净化技术可能会产生臭氧，臭氧具有鱼腥味，可以作为一个参考指标。超标的臭氧是对人体具有一定危害的。

In addition, some purification technologies may produce ozone, and ozone has a fishy smell, which can be used as a reference index. Excess ozone is harmful to the human body.

空气净化器要达到净化效果，必须根据房间面积、净化器的功率和净化效率等情况，持续开启一定时间后才能有效降低室内污染物的污染程度。在购买时需留意产品说明书，一般在产品说明书上都注明了空气净化效果检测单位出具的检测报告或合格证明。未给出实验条件，表述过于简单甚至绝对化的产品要慎重购买。

For air purifier to achieve purification effect, we must continue to open a certain time according to the room area, purifier power and purification efficiency, so as to effectively reduce the pollution level of indoor pollutants. In the purchase, we should pay attention to the product instructions. In general, the inspection reports or certificates issued by the air purification effect inspection unit are noted in the product instructions. A product that is too simple or even to be absolute is to be purchased carefully without giving the experimental conditions.
