According to the monitoring data of the environmental protection department, from January to November 2017, the PM10 concentration in 338 prefecture-level cities across the country decreased by 20.4% compared with the same period in 2013, and the PM2.5 concentration in Beijing, Tianjin, Hebei, the Yangtze River Delta, and the Pearl River Delta was lower than that in 2013. During the same period, they fell by 38.2%, 31.7%, and 25.6%, respectively, and the declines were significantly higher than the assessment standards. This is undoubtedly great news for us. The better the air, the healthier our breathing will be! Is the pollution still there? Unfortunately, the air has improved, but pollution still exists! Driven by national policies, it is inevitable that the air becomes better, but this does not mean that pollution will no longer exist! Just look at the US environmental report. Since the United States issued the "Clean Air Act" in 1970, atmospheric emissions have steadily declined. That is, while the economy continues to develop, the emissions of the most polluting sources must continue to decline. (As shown below) (2015 Air Quality Report of the American Lung Association) The American people still face the danger of air pollution o Ozone pollution: Looking at the entire country, the state of 2015 found that more than a quarter of people in the United States (almost 44%) live in counties with unhealthy ozone pollution o Particulate pollution: There are 287 counties, equivalent to 138.5 million Americans living in an air environment exposed to ozone pollution, or unhealthy particulate levels either for short periods or throughout the year. Compared with before, this is also reduced by at least 9.1 million people. According to the 2017 National Air Quality Report (United States), 4 out of 10 people in the United States still live in communities with unhealthy air quality. This means that despite the continuous improvement of the air environment in the United States, many Americans still live in places with unhealthy air! These air pollution may cause premature death risk, increased asthma, difficulty breathing, cardiovascular hazards and lower birth weight. How did the American people deal with these pollutions? The answer is to install a fresh air system! Dinike smart fresh air system is not only a new type of indoor ventilation and exhaust equipment, but also the best choice to comprehensively solve indoor air pollution!
