class='bigletter'>最常见、最实惠的口罩是 <a href='http://www.3m.com/product/information/N95-Particulate-Respirator.html'>3M N95 口罩</a>（上图适用于3M 9501 型号）。尽管价格非常实惠（每片 5 至 6 元），3M N95 始终是针对颗粒物（即 PM<sub>2.5</sub> 空气污染）表现最好的口罩之一。 9501 型号的一大优势是可折叠，因此您可以随时随身携带，而不占用太多空间。如果你忘记带One，你也可以在中国任何一家便利店（如7-11）购买这款口罩。</p> <p>“<b>N95</b>”标签代表口罩能够过滤至少 95% 大于 0.3 微米的空气传播颗粒（仅供参考，PM<sub>2.5</sub> 颗粒为 2.5 微米）。从所有<a href='http://www.myhealthbeijing.com/children/awesome-trio-of-pollution-mask-tests-the-winners-and-losers/'>测试结果</a>来看，N95足以过滤大部分 PM2.5 颗粒，但敏感人群可以考虑使用 N99 版本的口罩（N99 代表过滤 99% 的空气颗粒物）。请注意，型号为 <b>9001</b> 的类似口罩也很常见，符合 N90 过滤标准。</p> <p>请注意，为了真正有效，这些口罩应该正确使用和佩戴，以确保与面部良好“贴合”。您可以参考新加坡政府的此页面，其中有简单但很好的解释 <a

是一家专业的新加坡公司，自 2003 年开始生产自己的口罩。其设计和概念非常独特，对于经常外出的人来说非常有用。</p> <p>最近的一些<a href='http://www.cca.org.cn/web/xfzd/newsShow.jsp?id=66941'>研究</a>表明，totobobo 适合度测试的效果不佳与其他品牌一样：佩戴口罩时（即使是3M N95），贴合成型是必不可少的步骤，以确保没有未经过滤的气流。这种合身造型既是totobo的优点，也是其缺点。一方面，totobo拥有独特的热成型解决方案——这是其他口罩所没有的，但如果这一步做得不对，那么贴合测试就不会很好。如需了解更多信息，请查看<a
