Cambridge Mask Co Valve Deactivator Sticker

This is an optional adhesive valve cover and informational sticker advising others that the valve has been sealed and deactivated.

Enclosed are 2 stickers to “deactivate” our mask’s valve. The larger adhesive seal will deactivate the valve to prevent any chance of droplets being expelled. The smaller sticker shows to onlookers that the valve is deactivated.

Important note: the valve plays an important role in expelling moisture and reducing CO2. Therefore we only recommend using the seal stickers if you are legally required to. Although it is unlikely, if you do feel dizzy or have trouble breathing, remove the mask when you feel it is safe to do so and seek help immediately.
