The masks you link to have an exhaust valve, which makes sense for the intended non-medical use cases, but in a pandemic scenario that means the mask will protect the wearer from infected others, but will not protect others from a (potentially unaware) infected wearer. Aside from the ethical implications of that, if one lives in a place like Massachusetts or California or New York, it is not likely to satisfy masking requirements. Do you have an alternative suggestion without the valve?
The first one on this page, the ElastoMask Pro, filters bidirectionally. I have one and like it, very breathable, good deal. Though it’s one of the worst for intelligibility.
