"Fighting people" Wechat spread protection knowledge

Remember those days when the haze was serious, Xiaobian saw the news and saw such an article.

On New Year's Day 2014, many people will have to look at the AQI (Air Quality Index) in addition to watching the weather. Hangzhou, Zhejiang Province has a “post-80s” “hit on the Guardian,” and uses the WeChat social circle to protect knowledge of popular science and technology.

December 30th, "Is it occlusion or flicker? The articles of the eight “Flood Prevention” masks were widely distributed in the WeChat circle of friends and attracted the attention of netizens.

Fang Da was a “post-80s” person in Hangzhou, Zhejiang Province. He collected eight imported and domestic masks with relatively high sales volume. He compared the performance standards, material design rationality, and feelings of use. "Some domestic masks don't fit into the face after they are worn, and unfiltered air can easily penetrate through, failing to achieve the desired filtering effect. Some imported products perform EU standards, and filtering PM0.3 can reach over 80%. The filtration of PM2.5 is even better."

The “grassroots version” of the survey was posted on the Internet immediately after its release. “There are no hard-to-understand data for these professional laboratories, nor do they need much advanced knowledge and strong practicality.” Netizen “Little Muddy” said .

Fangda, 29, is a veteran “riding friend” who regularly participates in a variety of quasi-professional bicycle riding activities. However, the frequent occurrence of haze days this year has had a great impact on his daily training. Also riding in the misty ride, came back and obviously felt very hurt in the respiratory tract, would like to come to fear, "fight. Fonda spent 8,000 yuan money Haitao an indoor professional pedestal to be saved.

"But this is only an expedient measure after all. 'Hide' is not the solution." Since then, Fangda has started the "fighting survival mode."

Entering his home, you can see a white cube device in the living room is working. "This is a professional indoor air purifier that I bought exclusively from the United States. The unit price is over 10,000 yuan," Fangda said. In order to ensure the efficiency of purification, similar equipment is allocated to four rooms at home.

Fang Da pointed to a professional air quality detector called Dylos in the room and said: “The above figure 3577 represents the number of PM2.5 particles per cubic meter, indicating that the current PM2.5 index is 35.77, in good condition, before purification. The value of this is twice as high and it belongs to light pollution.” Fangda invested nearly RMB 80,000 in the area of ​​flood control equipment, which is a waste of money: “For your own health, the money is worth spending.”

Fangda told reporters that because of the mixed culture of the domestic air purification equipment market, in order to purchase highly reliable flood control equipment, he consulted domestic and foreign professional websites and self-learned related knowledge. Over time, he became the “hit-proof person” in the eyes of his friends. I also feel that I should share my accumulated knowledge and experience.

On November 22, 2013, Fangda officially opened the WeChat public account of the “Smog Survival Manual”. Haze poisoning symptoms and how to protect? How do you exercise for lovers of haze? How to choose and use masks and air purifiers correctly? How did London take off the "mistcap" hat? ... These questions can be found in the "Smoke Survival Manual." "Since we can't choose a living environment at the moment, we must understand what is going on with smog in the end so as to better protect ourselves." Netizen "Wandering Black" said.

Now, Fangda spends two or three hours a day writing, and sometimes spends several days using professional equipment. PM2.5 values ​​of people often come into contact with subway stations, car cars, and indoor and outdoor homes. To do the actual measurement, each time he will record the experiment process through video or pictures, and organized into text, through the "Mist Survival Handbook" release.

With these original contents, the "Smog and Survival Handbook" quickly "fired" in the circle of friends. The number of fans in the public account opened in the first month exceeded 10,000, especially in early December 2013. In those days, the number of fans soared at a rate of one or two thousand people per day. The feelings of this party are very complicated: “Seeing more and more people support and concern, of course, is a great sense of accomplishment, but at the same time I also deeply feel the helplessness and anxiety of everyone in front of the haze.”

Fangda now devotes almost all of his efforts to the maintenance of the "Smog Survival Handbook." He believes that the power of mutual help through the Internet can bring more attention to the surrounding air, water, food and other living environment security issues, "by virtue of a rational A good, learning, non-blind mind can survive in any crisis."

Fang Da was not alone on the road to flood control science. He has already found several “buddies” to maintain the public number. “If the public account is no longer noticed on that day, then it is no longer clear that the fog is no longer The problem is that it is the greatest success."
