The SelfRely.com mask ad that appears in the Wall Street Breakfast daily email has removable exhalation valves. That means an infected person can be exhaling the disease to all in proximity, but will still APPEAR to be covered by a mask, akin to a hidden and active lethal weapon. This is absurd!
I think you have a responsibility to your customers to investigate and stop promoting it. Duke University released a study about masks yesterday (8-10), and although it doesn't name the SelfRely mask specifically, it does make a point to warn against masks with exhalation valves or ports.
