1、 Fresh air fan completely solves indoor air pollution?

新风机只是综合治理室内环境的一个方面，严格来说，新风主要室内空气新鲜度问题。一般净化室内空气污染物，包括PM2.5、细菌与甲醛等污染物，换气次数需要达到8次/小时以上，新风量一般只占换气风量的30%左右，上为了，要求进一步降低新风。此外，室内空调、人与人的活动产生的污染物，新风无法净化。因此，完全依靠新风来净化室内空气污染物是不实际的。

Fresh air fan is only one aspect of comprehensive treatment of indoor environment. Strictly speaking, fresh air mainly solves the problem of indoor air freshness. Generally, indoor air pollutants, including PM2.5, bacteria, formaldehyde and other pollutants, need to be changed for more than 8 times / hour, and the fresh air volume generally only accounts for about 30% of the air exchange volume. In order to save energy internationally, it is required to further reduce the fresh air. In addition, the indoor air conditioning, human and human activities generated pollutants, fresh air can not be purified. Therefore, it is not practical to rely entirely on fresh air to purify indoor air pollutants.

二、空气清新剂能掩盖室内异味？

2、 Can air fresheners mask the smell in the room?

空气清新剂和香水等只能对污染物的异味起掩盖掩饰的作用，实际上原有的有害污染物还存在于室内中，继续影响和危害着身体的健康，同时劣质的空气清新剂还是会成为室内空气污染的来源，加重污染的程度。

Air fresheners and perfumes can only cover up the disguise of the peculiar smell of pollutants. In fact, the original harmful pollutants still exist in the room, which will continue to affect and endanger the health of the body. At the same time, the inferior air fresheners will become the source of indoor air pollution and aggravate the pollution level.

三、没有刺激性气味就没有污染？

3、 No pungent smell, no pollution?

各种物质混合在一起呈现的气味是很难辨别的，有的有毒有害气体是没有刺激性气味的，比如一氧化碳、二氧化碳、细菌等微生物凭气味难以判断是否超标。一旦能闻到明显的甲醛或是苯的气味时，空气污染已十分严重了。

It is difficult to distinguish the odors of various substances when they are mixed together. Some toxic and harmful gases have no pungent odors, such as carbon monoxide, carbon dioxide, bacteria and other microorganisms. It is difficult to judge whether they exceed the standard according to the odors. Once you can smell formaldehyde or benzene, the air pollution is very serious.

四、了装修污染，室内空气就了？

4、 If the decoration pollution is solved, the indoor air will be safe?

室内除了装修污染以外，室外大气污染物的侵入、空调通风系统以及人与人的活动，包括吸烟、烹调都是重要的空气污染物。

In addition to indoor decoration pollution, the invasion of outdoor air pollutants, air conditioning and ventilation system and human activities, including smoking and cooking, are important air pollutants.

五、一直生活在这样的环境中，有抵抗力了？

5、 Living in such an environment all the time, with resistance?

人的体质、抵抗力适应性各不同，不是所有的人在同一恶劣的环境下都会发病，所以造成了部分人的侥幸心理。人得过细菌、病毒感染，体内会产生一定的抗体，但是对于有毒有害的污染物质，人根本不会产生抗体，而且，这些有毒有害物质会在体内积聚，到了一定时候必然贻成大患。有资料表明，很多有毒物质还会影响人的遗传基因，危机到下一代的健康。

People's physique and resistance adaptability are different. Not all people will get sick in the same bad environment, so it causes some people's fluke psychology. When people are infected by bacteria and viruses, they will produce certain antibodies in their bodies. However, for toxic and harmful pollutants, they will not produce antibodies at all. Moreover, these toxic and harmful substances will accumulate in their bodies, which will inevitably cause serious diseases at a certain time. According to some data, many toxic substances will also affect human genetic genes and endanger the health of the next generation.
