Mix two parts of 100% silicon with one part corn starch and clamp the mold in place. Wait for one to two hours before removing it from the mold.\r\n\r\nIf you're using 3D Printing to make a valve, apply a thin coating of silicone on both the mask and valve to create a tighter seal.\r\n\r\nA Silicone Mold is added for face seal enhancement.\r\n\r\nTest the seal by placing your hand over the Filter cap and inhaling. There should be no air leaking in through the valves or around your face.\r\n\r\nCut to fit MRV 16, HEPA or MPR 2200 or above for replaceable filter functionality.
