自从入冬以来,雾霾一波接着一波袭来,这让口罩成为了生活必需品,那大家真的选对、戴对了口罩吗?今天williamhill asia 就来讨论一下这个话题。

N95口罩



N95口罩到底是个啥?

自从有了雾霾天,N95型口罩就成了当红产品。但其实大多数人都不知道N95是什么意思(小编痴呆脸:和82年的拉菲是一个起名道理吗?)。

这里的“N” 代表的是Not resistant to oil,也就是说这种口罩对油性颗粒没用,可以用来防护非油性的颗粒(举个例子,炒菜产生的油烟就是油性颗粒物,而人咳嗽产生的飞沫,细菌病毒等微生物,日常空气污染中的悬浮微粒和粉尘,就不是油性的,get没?)。

而“95”是指被它挡住的颗粒至少可以达到95%。所以啊,N95不是特定的产品名称,只要符合N95标准就可以称为“N95型口罩”。

一般来说,那个数字越高,表示防护效果越好,但同时呼吸的阻力也越大(小编给你翻译一下,就是戴上之后喘不上气)。因此,综合考虑防护性、舒适性和价格这三个因素,N95成了适合大多数人的选择。

N95口罩3天就得换一个!


N95口罩分为罩杯式和折叠式,它的防护效果肯定比一次性口罩和纱布口罩好。研究发现,N95口罩佩戴2天,过滤效率还能保持在95%以上,呼吸阻力变化不大(就是不妨碍你喘气儿);佩戴3天,过滤效率降低至94.7%,(也还是满足欧洲标准最低滤菌率94%的要求的);使用6天过滤效率就降到了90%。

考虑到一次佩戴N95口罩超过4小时就可能会导致头痛,所以如果需要一直佩戴,建议每4小时换一个。而在实际生活中,大多数人戴N95口罩都是只戴一会儿,但是会多次戴,基于上述数据,建议大家每3天换一次口罩,保存的时候还要注意在清洁环境中晾干后可以用干净的保鲜塑料袋短时间保存,避免污染。

这些情况需要立即更换口罩


①呼吸阻碍明显增加,也就是明显感到呼吸困难时;

②口罩跟脸不能紧密贴合时;

③口罩受到了明显污染时;

④口罩有破损时。



一次性口罩



一次性口罩有用吗?


一次性口罩分为医用防护口罩和医用外科口罩,我国规定医用防护口罩对细菌的过滤效率应达到95%,同时还要能阻隔液体喷溅物。也就是说一次性的口罩主要是防止飞沫,当大家防流感或者是去探望病人的时候,比较适合戴这样的口罩。但是不适合防雾霾。

一次性口罩能反复戴吗?


当!然!不!行!


在正确佩戴一次性口罩的前提下,口罩的滤菌率会随着佩戴时间的延长逐渐降低。研究表明,一次性口罩使用两小时内,滤菌率可以维持在95%以上,符合国家要求。

而反复戴一次性口罩,随着时间的延长,它的滤菌率会下降,口罩内、外的细菌总数都会显著升高,不仅不能有效防护,反而还增加了病原体的接触风险(细菌都被困在口罩里了,能好得了嘛~~~)。

一次性口罩要两小时换一次


一次性口罩不能反复使用,它的最佳使用时间是两小时。戴一次性口罩的亲们,要参考这个频率来更换哦~

棉质纱布口罩




棉质纱布口罩有用吗?


市面出售的印有卡通图案的口罩多为化纤面料,透气性较差,易刺激呼吸道或引发过敏反应,而且通常只有防风御寒的作用。所以,指望它防霾防菌防病毒你就输了~

常用的棉纱口罩一般是用脱脂棉纱布巾折叠数层后缝制而成。一般来说,3层纱布的口罩只能阻挡70-80%的细菌,6层纱布的口罩可阻挡90%以上的细菌。所以,使用棉纱口罩时,选择6-8层的比较好哦。不过,纱布口罩对于颗粒物的过滤率还不到30%,所以纱布口罩不能阻隔雾霾哦。

棉质纱布口罩每天都要洗


棉质纱布口罩的佩戴时间不应超过24小时,而且需要每天清洗。

具体清洗步骤分四步:

①表层清洗:使用家庭用消毒液、医用酒精浸泡棉纱口罩15分钟左右;

②夹层消毒:将棉纱口罩平铺在盆子当中,把烧开的热水浇灌在口罩上;

③漂洗:用肥皂搓洗口罩后用清水洗净,拧干;

④晾晒:将洗净的口罩放置在阳光下,暴晒晾干。

小提醒:雾霾天讲究多,口罩是最方便的防护措施,但是一定要戴对了才有用哦!
