Nox ear plug hygiene

I’m in earplugs 24/7 for nox but wondering how people manage hygiene and infection risk.

My plan is - new disposable pair daily - clean hands (obv) - letting my ear breathe during meals and once at night when it’s most quiet.

Is that enough or should I be doing something else?

Am I risking damage by letting it breathe so much? Feels like a catch 22.
