You can get a pack of 20 expired FFP2 masks for 99 cents (euros). They're safe, but the elastic band adhesive may fail, so keep a pack in your backpack just in case. I've gone through 125 with @scremlin since November last year and have only had the string adhesive fail on 2 of them. Both failed right out of the pack, so I put them in a separate baggy and will just reglue them on another occasion. Highly recommend if you live in the EU.
