P3 Mask Valve Blocker GVS
Description
This thing should prevent the GVS P3 Mask from leaking unflitered air. This is needed due to the Corona-Pandemic to prevent others from breathing your aerosols. To use this thing you have to remove all three valves and insert the printed part. It should fit nicely and stops all air from leaking through the middle vent. Please verify proper sealing. This thing comes without any warranty. Please do not wear this mask longer than two hours. In Germany it is forbidden to wear such a mask longer than 90 minutes (at work) and then you need a 30min break.
