Air quality sharp turn behind the Beijing air purifier "fall"

In the Beijing market, there's a product that once sparked intense demand. Two winters ago, it was nearly impossible to get your hands on it. But this winter, it's been left dusty in the corner of a mall, with very few people showing interest. It's an air purifier. Before the smog engulfed the capital, the air purifier industry experienced a frenzy. Sales grew year after year as people rushed to buy them, especially during winter. However, by the end of 2017 and into early 2018, the smog began to clear. Blue skies returned, and the air purifier market suddenly faced a dramatic downturn. Offline retail sales dropped by 60% year-on-year, a shocking decline felt most directly by appliance stores. At Suning Appliance’s Chaowai Street store in Beijing, the second-floor small appliances section now has only a few brands of air purifiers displayed together in a small space. According to sales manager Zhou Xia, in previous years, each brand had its own dedicated area. This year, due to low demand, they've been grouped together. Winter has always been the peak season for air purifier sales, but the madness of the past two years now feels unimaginable. People used to rush to buy expensive units like they were buying cabbage. Citizen Wang Ke recalls that in 2015, he would run from store to store in Beijing, only to find none in stock. Orders could take over two months to fulfill. This year, such scenes are gone. The electric kettle counter next door can sell two or three units a day, while the air purifier section might not even manage that in a month. The overall data supports what individual stores are experiencing. According to a report from Aowei.com (AVC), retail sales in the Beijing-Tianjin-Hebei region fell by more than 60% year-on-year in December 2017. Online sales saw a similar drop. Li Hongtao, PR head at Jingdong Mall’s Home Appliances Division, noted that 2017 marked the first time Beijing’s air purifier sales declined nationwide, dropping from nearly 50% to around 30%. The sudden drop in sales is largely due to a sharp improvement in air quality. The Beijing-Tianjin-Hebei region, once the worst-hit, saw a remarkable turnaround at the end of 2017. For two months, the air was surprisingly clean. For those who rely on air purifiers, the weather makes all the difference. Deng Wei, a 40-year-old Beijing architect, has been capturing daily photos of the sky for four years. His project, “2016 Haze Calendar,” showed the gray skies of that year. He started this project after seeing children in smog-filled schools and feeling the need to document the change. Now, his 2017 photos show brighter skies, clearer views, and more blue days. These changes reflect real improvements in air quality. According to the Beijing Environmental Protection Bureau, the average PM2.5 concentration in 2017 was 58 μg/m³, meeting the goals set in the "Atmosphere Ten" action plan. In 2016, the number was still 73 μg/m³. The success of these efforts came from both favorable weather and strict pollution control measures. Professor Wang Shuxiao from Tsinghua University emphasized that while favorable weather helped, the real change came from aggressive environmental policies. Over the past five years, Beijing significantly reduced coal use, shut down polluting factories, and increased enforcement against violations. Joint efforts across the Beijing-Tianjin-Hebei region have also contributed to cleaner air. This shift in air quality has impacted the air purifier market. Industry experts predict continued improvement in 2018, which means limited growth for air purifier sales. Major manufacturers are focusing on reducing inventory rather than expanding production. However, the current penetration rate of air purifiers in China is still low, at around 5%, leaving room for future growth. As dawn breaks, Deng Wei takes another photo through his window. The sky is blue, and the distant mountains are visible again. He plans to organize his 365 photos from 2017, renaming the project from “Smog Calendar” to “Blue Sky Calendar.” The transformation has been real, and for the first time in years, he sees a future where clean air is no longer a luxury.
