海外網購口罩攻略（內附全球大量網店連結）
新型冠狀病毒在國內迅速擴散，香港亦已有確診個案。這件事令香港市民極度恐慌，各區出現口罩搶購潮，不論是消委會測試後推薦的醫護口罩，3M 口罩，還是價錢不平的 N95 豬嘴口罩。多間藥房，批發，萬寧，屈臣氏，日本城，莎莎，卓悅，華潤堂等均出現供應不足。其實，除了在藥房 / 百貨公司可以搶購到口罩之外，淘寶以外其實不少鄰近地區的網上商店均有口罩訂購。
如何選擇口罩
戴口罩是阻斷呼吸道分泌物傳播的有效手段。目前市面上能看到的口罩主要有醫用防護口罩（例如 N95 口罩）、醫用外科口罩和普通級別的一次性使用醫用口罩。此外，市場上還有各種明星時常佩戴的棉布口罩、海綿口罩等。市民日常防護選擇醫用外科口罩就好。 N95 口罩的防病效果更好，但透氣性差，呼吸阻力較大，不適合長時間佩戴。而購買口罩需要注意以下事項：
1. BFE (bacteria filtration efficiency) 是細菌阻隔率，數字愈高便是最有效能阻隔細菌。(樣本大小: 3μm, 容許: 1-5μm)
2. PFE（Particle Filtration Efficiency）則是顆粒過濾效率，數字愈高便是最有效能過濾顆粒。(樣本大小: 0.1μm)
3. VFE (virus filtration efficiency) 是病毒阻隔率，數字愈高便是最有效能阻隔病毒。(樣本大小: 0.1-5μm, 載體: phiX 174)
如果你是十分著重這個效率，就要留意的是樣本大小，由於實驗室所用的樣本大小有不同，對效率結果亦有所影響。不過，其實不是所有品牌都會為口罩進行VFE 測試，例如: 英國就會用ASTM LEVEL 標準代替。
跟據網上資料，2003年SARS病毒大小是0.08-0.14μm。故此，有研究人士十分著重這個樣本大小及效率。至於，如是防塵/防花粉口罩的話，這些口罩就不能有效防止細菌及病毒，請盡量不要購買。至於如果口罩只標示PM2.5，能夠有效阻擋空氣中的直徑為2.5微米或以上的細懸浮粒子，例如是二手煙和空氣污染的粒子。但是由於病毒遠小於 2.5微米，故此，只標注PM2.5 而沒有其他，就未必有用了。
