雾霾天，空气净化器到底有没有用？
1.空气净化器到底有没有用？
1. air purifier in the end there is no use?
有报告显示，我们现代人有80%的时间待在室内，人均室内PM2.5的吸入量是室外的4倍。而雾霾天即便门窗全闭，若不采取净化手段，室内PM2.5的浓度至少有室外的1/3。
The report shows that 80% of our modern people stay indoors, and the indoor PM2.5 intake is 4 times as much as that outside. And haze days even doors and windows closed, if not take purification measures, indoor PM2.5 concentration at least outdoor 1/3.
所以，正确使用空气净化器很有必要，能提升室内空气质量。
Therefore, the correct use of air purifiers is necessary, can improve the indoor air quality.
2.净化器要开多久才能起作用？
How long does it take for 2. purifiers to function?
一般的空气净化器可能会20—30分钟才会见效，室内的污染物才会开始降低，这说明该净化器的净化能力是不行的。
The general air purifier may take effect in 20 to 30 minutes, the indoor pollutants will begin to decrease, which shows that the purification capacity of the purifier is not enough.
净化器的工作效率取决于洁净空气量（CADR），即单位时间提供“洁净空气”的多少。CADR值越大，说明净化器的净化能力越强。
The efficiency of the purifier depends on the amount of clean air (CADR), that is, how much clean air is provided per unit time. The greater the CADR value, the stronger the purification ability of the purifier.
举个栗子，一个40立方米的空间，如果用的是CADR为40的净化器，那么算下来将室内空气净化干净需要大约3小时。而如果使用CADR值为650的亚都双面侠P6Plus，净化干净则只需要几分钟。
Take a chestnut, 40 cubic meters of space, if you use a CADR 40 purifier, then it will take about 3 hours to clean indoor air. And if you use the YADU double faced P6Plus with CADR of 650, it takes only a few minutes to clean up.
3.雾霾严重时，能开窗通风吗？
3. haze serious, can window ventilation?
小编建议您一定要在开窗换气和空气净化中间找好平衡。即便室外空气很糟糕，但人员密集的室内场所还是应该择机通风的，因为长期不通风换气的室内，二氧化碳浓度会升高，其数值到达一定高度时会对人类认知行为产生显著影响。
Xiao Bian suggests that you must find the balance between window ventilation and air purification. Even if the outdoor air is very bad, the crowded indoor place should choose the ventilation, because the long-term non ventilated room, the carbon dioxide concentration will rise, the value of a certain height will have a significant impact on human cognitive behavior.
在室外PM2.5监测值低于75微克/立方米即为优良时，开窗通风有利于室内空气质量的提升，而在室外PM2.5监测值高于150微克／立方米时，开窗通风这一行为不仅会成为室内空气质量的一项破坏因素，相信其他人也会给你一个360度白眼。
In the outdoor PM2.5 monitoring value below 75 micrograms / cubic meter is excellent, the ventilation window is conducive to indoor air quality improvement, while outside the monitoring value of PM2.5 is higher than 150 micrograms / cubic meter, the ventilation window this behavior will not only become the indoor air quality of a destructive factor, believe that other people will also give you a 360 eyes.
我们可以通过天气预报实时查看室外空气质量，人们可以选择一天中空气质量相对较好的时间点通风换气。
We can see the outdoor air quality in real time by weather forecast, people can choose the air quality of the day relatively good time point wind ventilation.
4.净化器应该摆在什么位置？
Where should the 4. purifier be located?
净化器要摆在离自身所处空间较近的位置。
The purifier should be placed close to the space where it is located.
专家指出，PM2.5的悬浮时间相对较长，如果人和净化器相距较远，人体周围的空气质量就不会得到尽快改善。最好是人在哪里，就把净化器放在旁边，其他不用的房间门都关上，保证自身周围空气的洁净。
Experts pointed out that the PM2.5 suspension time is relatively long, if people and purifier far apart, the air quality around the body will not be improved as soon as possible. The best place for people is to put the purifier on the side, and the rest of the rooms are closed to ensure the cleanliness of the air around them.
5.该如何选购空气净化器？
5. how to choose air purifier?
按照新版《空气净化器》国标，洁净空气量、累积净化量两项评价净化能力的指标是核心。CADR代表着净化器的净化能力，累积净化量（CCM）则是CADR的耐久性指标，级别越大，寿命越长。
According to the new edition of "air purifier" GB, clean air volume, cumulative purification capacity of two indicators to evaluate the purification capacity is the core. CADR represents the purification capacity of the purifier, and the cumulative purification capacity (CCM) is the durability index of CADR. The longer the grade, the longer the life.
