Masks at the airport?

I’m flying out of Seattle at 7 this morning and I walked out of my apartment without my trusty N-95s.

I’ve worn masks for travel for years (way pre-COVID) because I always catch a cold otherwise. So I feel like a real dunce.

Anyway, does anyone know if there’s a place at the airport that sells masks? Five years ago it would have been a given, but now I’ve got no idea and don’t want to go on a wild goose chase.

Alternatively, if you’re at the airport and have an extra mask, I will happily buy it off you!

I’m flying out of terminal B.
