In all honesty, I've yet to find a flexible N-95 of any kind that doesn't seem to leak like a sieve around the nose. If someone is cool with that wearing it fairly loose is pretty comfortable... this is how I almost always see people wearing them, they're obviously not sealed at the upper edge.

I imagine it still helps some, but I'm very attentive to leaks at the top because glasses. If you wear it loose enough the gaps at the top are so big it doesn't fog your glasses anymore, I go the opposite direction and fiddle with it all day long trying to get the nose piece rigid enough to stop the leak. I'm not sure which approach is more risky... touching your mask is a nono too.

I guess a good mask with leaks is better than a surgical mask maybe, dunno if it's better than a rigid mask with an exhalation port TBH though, at least if you're not exhaling strongly there are no leaks and it's good for personal protection -- and since we've as a country decided it's everyone for themselves I feel pretty okay wearing a vented rigid N95 in an environment with a bunch of unmasked people.
