Why surgical masks have a blue and white side?

why do some surgical masks has different colours at each side (one side is white and the other blue)- does it matter if you wear the white side inwards and the blue side outwards?





any explanation for this?Why surgical masks have a blue and white side?
so you can see which side you started with..do one operation, flip the mask over and go to the next one...saves money!!


or if you sneeze in OR, you can just flip your mask to the fresh side, and keep on cuttin' !!Why surgical masks have a blue and white side?
A surgical mask was made in two different colors are obviously for user to differentiate the the sides from one and other. As we can observe, the colored side was designed to have a lower water absorbent ability as the other side (white) designed w/out this feature. Hence, without any doubt, the inner side should be colored in-order for the surgical mask to provide better protection and comfort for the user throughout the day.


P/s: As we speak, we tend to release tiny sprays of saliva which one of the reason the colored side being made that way.
Check the packaging they came in - should tell you. There's no way to guess they are all different!
