How to choose the right mask for you
The ability of the mask to fit snugly against the wearer's face determines whether or not the mask will actually work in real combat.All masks leak to a greater or lesser degree when worn on the face, and no mask is absolutely airtight.
However, if it becomes apparent that the mask will not fit the face, a large amount of dirty air will continue to flow between the wearer's breaths, thus rendering the protection ineffective.
Each time you put on the mask, check the airtightness of the mask according to the instructions for use (consider the sticker). If it is obviously not tight, do not use it!
