    FDA demonstrates how to use rice cookers to disinfect used face masks (2020/04/05)

    With the nation donning masks to fight COVID-19, surgical masks have become a precious commodity. Can the lifespan of a face mask be extended? The Taiwan Food and Drug Administration showed us how. It turns out that all you need is a rice cooker.

    At the Central Epidemic Command Center’s daily press conference, a rice cooker became the center of attention. Health Minister Chen Shih-chung tried to demonstrate how to use it to extend the lifespan of a used mask.

    Laughter broke out after the minister mistakenly put the rack inside the inner pot. After the rack was placed in the right spot, which is under the inner pot, the used mask should go inside the inner pot, which stands on the rack. The thing to remember is that no water should be added. Just turn on the appliance, let it cook for three minutes, and then let it sit for five minutes before removing the lid. The mask is then completely disinfected.

    Wu Shou-mei, Director General
    Food and Drug Administration
    If you put water in it, it’ll affect the mask’s static electrical layer. So what about using alcohol to disinfect it? Actually, that’s not a good idea.

    Since the temperature of the inner pot reaches 165 degrees, all the germs that need to be killed are killed.

    The FDA found that rice cooker disinfection can kill more than 99% of the germs and lower the mask’s efficiency by just 1% to 2%. It advises that a used mask can be disinfected this way four to five times at most. However, if a mask is soiled, torn, or is used by someone with a chronic disease or respiratory symptoms, it should be discarded.

    口罩電鍋乾蒸三分鐘 靜置五分鐘大功告成

    今天的疫情記者會上,食藥署示範電鍋乾蒸口罩,讓口罩高溫殺菌後可再重複使用。來看看怎麼做。

    疫情中心記者會,竟把電鍋端上桌,陳時中帶頭示範,怎樣延長口罩壽命。

    只是部長竟將鍋架放在內鍋,被笑平常沒在煮飯。放入內鍋架後、再放內鍋,口罩置於內鍋裡以防融化,且要注意一滴水都不放,乾蒸三分鐘,再靜置五分鐘,充分殺菌後就大功告成。

    [[食藥署署長 吳秀梅]]
    “放水其實這個會影響到我們口罩本身的靜電層,那我用酒精來消毒好不好?其實也不好。”

    [[中山醫學大學副教授 賴全裕]]
    “因為他裡面內鍋壁的溫度已經達到165度左右,所以該殺死的細菌應該都死了。”

    食藥署研究發現,口罩電鍋乾蒸法,能殺菌99%以上,減低效率1到2%,最多重複4-5次。但口罩有髒汙、破損,或民眾有慢性病、呼吸道症狀,就不建議再消毒。
