Mask Specification


This test indicates how well a mask filters droplets containing biological agents such as bacteria or viruses. The higher the BFE, the more effective a mask is in preventing bacteria-containing droplets from reaching the wearer. Our masks are locally lab graded (ASTM F2101) with BFE > 95%.


This test indicates how well the outermost layer of a mask repels water. The higher the water repellency on its outermost layer is, the better a mask is at protecting the wearer from droplets emitted by others that might contain bacteria or viruses. We use Dupont Teflon, which is a world-renowned waterproof treatment in the world.


Breathability is determined by a Differential Pressure test. This test determines how breathable a mask is by measuring how easily air passes through from one side to the other. It does so by calculating the difference in pressure across the surface at a flow rate of 8 liters per minute. The lower the DP of a mask, the more breathable it is. A good rating would be anything below 6.0 mm H2O/cm2 and our mask has an average of 3.56 mm H2O/cm2 which is better than the average good rating.


SILVADURTM technology is an innovative antimicrobial treatment that improves on earlier technologies by using charged silver ions as opposed to silver particles. Silver ions evenly distribute over a garment. This means the silver is used more efficiently. Silvadur is one of the WORLD’S BEST antimicrobial treatments.
