Under the dome, anti-fog FILTECH fly - whole house synchronous air purification
Chai Jing’s self-funded in-depth film survey on the smog “ Under the Dome ”, with systematic ideas, extensive surveys, detailed data , vivid The diversified audiovisual language gave everyone a vivid 'smog class'. Since the broadcast, the video has been clicked for hundreds of millions of times, and the circle of friends has been blown up. Chai Jing mentioned in the speech: In the worst case of smog, she had to keep her daughter at home to escape the smog. Going out to fight the vaccine, even if the child opens his mouth and smiles at himself, he is very worried. There is a section in Chai Jing’s video about children’s physical education classes in heavy fog. I believe that every parent will worry that we cannot always “caught” children, and one day they will be exposed to smog. How do we protect children under the dome and let them breathe clean and safe every time? Let's take a look at the common ways of child prevention and see if these methods are scientific and effective.
Is it useful to stay indoors in a foggy day?
It is well known that smog days try to stay indoors and close the doors and windows . However, when the outdoor air PM2.5 index bursts, the children who hide the doors and windows are indoors, is the air breathing safe? According to the research data of the IAQC (INDOOR AIR QUALITY CONTROL) laboratory of Hangzhou Kali Intelligent Technology Co., Ltd. If no measures are taken, when the concentration of outdoor PM2.5 is high, the indoor concentration will generally be consistent with the outdoor. Closing doors and windows for a long time can also lead to an increase in indoor VOC, formaldehyde, and helium concentrations. The concentration of outdoor PM2.5 and the release of indoor pollution sources will affect the quality of indoor air. In another set of comparative tests, the INDOOR AIR QUALITY CONTROL laboratory `s residential test data for the installation of FILTECH`s full-room synchronous air purification system showed that clean fresh air () was continuously entering the room without opening. The window can be ventilated to make the indoor air clean and fresh.
Asked where the channel is clear as water, only the active head comes alive. The smog days reduce outdoor activities and try to keep the children indoors, but the premise is that the room has a safe and effective air purification treatment device to ensure indoor air circulation and purification.
The United Kingdom began to suffer from smog in the 1950s, especially in the two months after the smog incident, nearly 8,000 people died of respiratory diseases. In order to effectively curb the smog, the United Kingdom enacted a number of laws such as the Air Cleansing Act. The government funded the renovation of the home fireplace and replaced the coal with clean energy gas. The general public`s understanding of smog has gradually deepened. By 1999, 97.81% of households in the UK had installed a fresh air system to protect their families` breathing health. However, ordinary families in China still lack awareness of air purification, and they still lack attention to the importance of the fresh air system .
In 2014, the IAQC (INDOOR AIR QUALITY CONTROL) laboratory tested the filtration effects of more than 10 types of anti-smashing masks . The test data showed that there were very few anti-scratch masks. A mask that filters PM2.5 is effective and must be very tight. Is it feasible to wear a high-resistance mask for children? Take the N95 mask as an example: the N95 mask is an industrial dust mask, which has a catching capacity of 95% for particles smaller than 0.3 μm, and has a remarkable anti-mite effect. However, the US Food and Drug Administration (FDA) data show that wearing N95 masks will increase respiratory resistance, so the US Food and Drug Administration recommends that patients with chronic respiratory diseases, heart disease or other dyspnea-prone diseases should use such masks. Consult a medical professional. The German labor insurance regulations more clearly stipulate that workers should not wear N95 masks for more than half an hour each time; for every half hour of N95 masks, they must take off their masks and breathe normally for more than half an hour. Otherwise, it may cause damage to the respiratory system and, in severe cases, even cause hypoxia and fainting.
Tests have shown that professional anti-mite masks are closely attached to the human face, and the filtering effect is good, but the airtightness is strict and the airflow resistance is increased. It is much more difficult to "inhale" and "exhale". Children`s respiratory system is not mature, and a tightly sealed mask will increase the breathing burden and affect physical development. Therefore, children are especially concerned that they cannot wear anti-mite masks for a long time.
Is it feasible to install an air purification system in a school dormitory or other places ?
Schools are the longest place for children to stay each day. Is it feasible to install an air purification system in schools? In December 2014, Hangzhou Carly Technology installed the FILTECH fly-to-house synchronous air purification system in a student apartment (200 square meters) and classrooms in Hangzhou , and collected data every 3 minutes for 24 hours. According to the report, FILTECH`s air purification system plummeted within 1 hour of the whole house synchronous air purification system. After about 3 hours, the air quality of the apartment reached the excellent standard (). FILTECH is flying. The noise of the whole house synchronous air purification system is about 30 decibels, and the power consumption is only 1 degree in 24 hours.
The installation of air conditioners in teaching buildings is now very common, but the air purification system that protects the health of children and faculty is hard to find. We are very eager to see that innocent classrooms, innocent schools, innocent quarters, etc. can emerge as soon as possible to protect the children`s respiratory health.
In the current ten-faced “?”, the air quality should be improved in the short term, and the use of air purification equipment indoors is the most obvious way to achieve the quickest effect. In the long run, the improvement of the air requires each citizen to adopt a low-carbon green lifestyle and make efforts to improve the atmosphere. Put less fireworks, drive one less day, smoke less, use less electricity... Don`t be good and don`t do it. Just like Chai Jing said: "A person knows that he has done a little bit of things that can make things better. He can be practical in his heart. Looking back at the war between humans and pollution, ... is thousands of dollars. An ordinary person, one day they said no, I am not satisfied, I don`t want to wait, I don`t want to push it anymore, I have to stand up and do something, just at this moment, right here, here!"
