This particular mall (Landmark North) is quite close to the China border, hence that last item on the list. I’d never seen such a suggestion before. :)

Does anyone else delete posts just because the photo doesn’t look right with all the rest of the photos already posted? The last one I deleted just didn’t have the right margins. [sigh]

THE TOP POLLUTION BUSTING FACE MASKS
As pollution levels again reach shocking levels all over China, people are once again getting very particular about their particulate matter. The latest wave of pollution in major Chinese cities has seen a proliferation of all kinds of masks breaking out in convenience stores, Taobao and just about anywhere else a trader can make an easy buck.
Packaging on the masks lure consumers in with technical buzzwords – N 95, PM 2.5, anti-pollution, anti-bacterial, and anything that sounds suitably scientific – and every other package seems to have the 3M logo or at least something vaguely resembling it. Fortunately, The Shanghai Consumer Rights Protection Commission released a report in late 2013, looking at the efficacy of 17 different disposable masks commonly available on the Chinese market.
Staff at the commission purchased two masks in stores and 15 online. Using the GB 2626-2006 filtertype dust respirator mask as their standard, they tested each mask for filtration efficiency, leakage, resistance to breathing in, resistance to breathing out as well as several other indicators.
Two masks didn’t even meet the basic GB 2626-2006 standard requirements. In terms of the primary criteria, filtration efficiency, there were seven samples with a filtration efficiency greater than 90 percent , eight samples that were less than 50% percent, the lowest mask only managed a mealy 6.5 percent. The detailed results of the study can be found on this spreadsheet.
Best Five Disposable Masks
Dr. Richard Saint Cyr, a family physician with Beijing United Family Healthcare posted his take on the results on his website My Health Beijing.

“I narrowed the list down to a handful of the top five you should look for, all of which had filtration efficiency over 95%, leakage rates under 7%, and low breathing resistance rates. They are the 3M 9041 and 9010; MASkin 6135;  3L N95; and Gangkai KN95 港凯KN95防尘口罩. My vote for the best is the usual gold standard: 3M, with two masks that did well here.”

One mask that didn’t make his list was GirodMedical, which actually had the highest score with an impressive filtration efficiency of 99% and leakage rate of just 0.7%, but its was more difficult to breathe than with the other masks. No mask achieved the holy grail of both perfect filtration and no leakage, whilst allowing for good ventilation.

3L N95 mask

Many western consumers in China question the authenticity of the 3M products and model numbers of the mask sold in stores and online, especially as they don’t match with model numbers in their US website. Here is 3M China’s official webpage listing their extensive array of masks available for the China market.
Worst Five Disposable Masks
Dr. Saint Cyr listed some of the worst masks in terms of poor filtration and high air leakage. One factor in diminishing the effectiveness of the masks is the use of pleats, “all those pleated ones just don’t seal well, even if the fabric is technically effective,” he said.

适美佳活性炭口罩


佳佰颗粒物防护抑菌口罩


翔翊一次性使用口罩

The biggest loser on this list was the knitted mask (针织口罩) by Beijing ZhongBei Bojian Technology and Trading, it was only able to keep out 6.5 percent of particles; you’re probably better off wearing a bandanna or a napkin!

Awww, the weird cloth plaid ones look more fun. :P (This article is actually super helpful…*looks up more mask reviews on the internet*)
