The proper way of wearing
facemasks
· If we have flu, the white side
should be to our our face (the
color side faces out) to filter
the microorganism for
spreading to others.
· If we are not ill, the white side
should face out to protect
microorganism from outside to
have contact with us.
原來口罩要這樣戴:
1、感冒時:白色戴裏面,顏色
在外面,以免感染別人;
2、如果沒感冒:白色戴外
面,顏色戴裏面,以免被別人
感染。
口罩過濾功能原是這樣設計。
