For some N95 masks, that's because they assume you are using it to block out particles that will accumulate on the mask, like paint droplets or sawdust or whatever.
In contrast, breath is mostly water vapor, and COVID-19 particles have a short-enough half-life that you can probably rotate between masks and be pretty safe.
