But according to their website, filtering efficiency is same as surgical masks?
Bacterial Filtration Efficiency (BFE) > 95%
Melitta starts production of millions of face masks
The shape is already kind of looking promising... as long as it doesn't break or tear or anything like that lol.
どんなメーカーのコーヒーフィルターでもいいわけではないような事がどこかに書かれてましたが、
もう何も覆うものがなかったらコーヒーフィルターとか、掃除機フィルターとか重ねて使ったらなにもないよりはましなのかも？！
