Because your trust is so important to us, we feel it's critical to be transparent with our test reports by making it publicly available.

The following reports prove that Flo Mask performs at the highest levels, as tested by renowned laboratory institutions in the USA and abroad. And unlike other elastomeric mask companies, we make it a point to test our masks as a complete system, not just the filter.
