One of the key measures for mask “breathability” is pressure drop
For instance, 3M N95 masks which many have reported feel comfortable have lower pressure drop than others
When CDC says N95s are “too uncomfortable”— assume all masks are the same (false!)

It’s about how it will look politically to backtrack on what masks are best

3/ and then what a commitment to providing high filtration masks consistently & nationally will actually entail, from admin & cost perspective
And the challenges associated with increasing mask uptake
Yes- public health is really tough

4/ But right now— we need to ramp up all efforts to slow down infections
And if you’re going through the trouble of having indoor mask mandates anyways, why not optimize these with the best masks that you can? Make them freely / ubiquitously available during surges esp
