1、 Fresh air fan completely solves indoor air pollution?
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.
2、 Can air fresheners mask the smell in the room?
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.
3、 No pungent smell, no pollution?
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.

4、 If the decoration pollution is solved, the indoor air will be safe?
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.
5、 Living in such an environment all the time, with resistance?
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.
