More breathable than paper but why are you doing this to yourself?
Bought as a test. Slightly more breathable than paper masks, not as breathable as mesh.  If you are looking for the most breathable mask for work or air travel try a mesh mask, not this. Besides even here in NYC  hardly anyone is wearing masks at all and if they are they aren’t wearing it properly. Save your money and don’t buy this mask, if you’re going to buy a mask get a mesh mask.
