Outdoor air pollution is getting worse and the air quality is not optimistic. The indoor air pollution caused by decoration is also becoming more and more prominent. On the one hand, people are seeking modern technology to alleviate pollution. On the one hand, they are also looking for a balance psychologically, and comfort themselves with some self-righteous ideas. So, which ones are more reliable?
1. The new fan completely solves indoor air pollution?
The new fan is only one aspect of comprehensively managing the indoor environment. Strictly speaking, the new fan mainly solves the problem of indoor air freshness. Generally, indoor air pollutants are cleaned, including PM2.5, bacteria and formaldehyde. The number of air changes needs to be more than 8 times/hour. The fresh air volume generally only accounts for about 30% of the air volume.
Yes, it is required to further reduce the fresh air. In addition, indoor air conditioning, pollutants generated by human activities, 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 indoor odors?
Air fresheners and perfumes can only mask the odor of pollutants. In fact, the original harmful pollutants still exist in the room, continue to affect and endanger the health of the body, and inferior air fresheners will become indoors. The source of air pollution increases the extent of pollution.
3. No pollution without irritating odor?
Wu Jixiang, a professor at Shanghai Jiaotong University and chairman of Shanghai Sanyin Environmental Protection Technology Co., Ltd., said that the odors of various substances mixed together are difficult to distinguish. Some toxic and harmful gases are not irritating, such as carbon monoxide and carbon dioxide. Microorganisms such as bacteria are difficult to judge whether they exceed the standard by smell. Once you can smell the obvious smell of formaldehyde or benzene, air pollution is very serious.
4. Solved the pollution of the decoration, the indoor air is safe?
In addition to decoration pollution, indoor air pollutant intrusion, air conditioning ventilation system and human activities, including smoking and cooking, are important air pollutants.
5. Have you been living in such an environment and are resistant?
People's physical fitness and resistance adaptability are different. Not all people will develop in the same harsh environment, which has caused some people's luck. People have been infected with bacteria and viruses, and certain antibodies are produced in the body. However, for toxic and harmful pollutants, people will not produce antibodies at all. Moreover, these toxic and harmful substances will accumulate in the body and will inevitably become a major problem at a certain time. There is information that many toxic substances can affect human genetics and crisis to the health of the next generation.
6. A high-end air purifier can solve the problem?
Air purifiers have many technical indicators, but the most important indicator is whether the user can reach the standard after use. High-quality air purifiers When the indoor pollutants exceed the standard by 10 times, the standard will be reached within 1 hour after starting the machine. It is unprofessional to talk about the purification efficiency without condition. Moreover, a single air purifier is difficult to solve the problem of excessive formaldehyde in the house. To meet the safety standards for formaldehyde, it must rely on comprehensive methods, including ventilation, pollution source control, chemical treatment and air purifiers.
