Be safe and enjoy time with family, Pearl Huynh 非常时期口罩买不到怎么办?自制防病毒口罩应急使用,跟专业的还是有很大的差距,但好过没有吧? 热心网友建议: 口罩基本有三層,防水,防菌微粒塵,吸水,你的口罩只能防麈不能防疫,外層要防水,普通布沒用建議自製口罩也要三層,吸水(最內)層可用沫手紙(kitchen paper)重點高效吸水!!! 防病菌微粒以及塵(中間)層,建議不計成品用3M空調濾網,重點是要防病毒病菌,最好用大牌子包裝列名防菌!!! 防水(最外)層要用防水透氣物料最好用不織布,用前切記抹乾淨,如找到不計成本現仍可在藥房找外科醫生膠布,例如3M nexcare transpore clear tape,計住要防水加透氣!!! 要貼滿表層別漏洞 有些人建議用膠片開洞做防水層並沒有效 因仍有機會空氣水分受污染而透過透氣孔吸入 紙巾+廚房紙+透明膠DIY口罩 港大外科醫生:功效可達外科口罩9成 https://youtu.be/yscK5ByDalU 史上最簡單口罩保護套作法 免工具 人人都會 /愛迪先生 https://youtu.be/IPe...
