السلام عليكم

Baru sebentar tadi saya berbalah dengan sahabat cara penggunaan surgical mask yang betul. Saya cakap putih luar dan dia cakap putih dalam. Setelah google ternyata dia berada dipihak yang benar..

صدقت يا أخي

Memang putih di dalam dan yang warna di luar...

Determine which side of the mask is the front. The colored side of the mask is usually the front and should face away from you, while the white side touches your face.

Update:... ada juga pendapat yang lain...

There are two sides of the surgical mask which are white and blue. The white side contains filter and if you have flu, it should be attached to your face so that the blue side faces out so as to prevent the germs from spreading outwards. If you are not ill, the white side ought to be facing out to protect micro-organism from the environment to come into contact with you.
