UPDATE, March 2015: Please check out my buyer’s guide to air purifiers; my 2014 review of the science behind air purifiers; my 2015 tests of air purifiers under 1,000 RMB plus my 2014 review of two dozen top air purifier models in China.
Which is the best air purifier for China? I get asked this question all the time, and my articles discussing my own test results still are the most popular articles on my website (here, here and here). But I’m just one data point and can’t try all the models available. For objective tests, I’ve always been telling people to read the independent Consumer Reports test results, as well as the reviews from Consumer Search. But finally we have new data points specific to the machines available here in China. Mentioned in Shanghai Daily, they report on the Shanghai Consumer Rights Protection Commission’s new analysis of 22 air purifier models. They focus on PM2.5 and formaldehyde, arguably the two most serious indoor air pollutants on our health. Quite a few brands didn’t do so well! Anyway, the original article is in Chinese but I’ve Google Translated the table below. How did your model do? I’m happy as my home’s Blueair did great, removing 97-99% of both formaldehyde and PM2.5; I don’t see results for my IQAir here. But there are many others: Panasonic, Daikin, Sharp, Yadu, Honeywell…
