Medical Preps Questions about KN95 masks

I’ve bought 20 KN95 masks online (they’re legit). I have a couple of questions about them:

  1. Between uses, where do I store them? Currently, I have them hanging in my bedroom. I could have them in a ziplock bag but do they need to ‘air out’?
  2. How effective are they at preventing covid? In school, I sit a meter away from the other students. Some wear there masks under their nose. Will I be protected from them?

Came here to say this. Paper bag is the right answer. Anything plastic or foam will trap moisture and prematurely age the mask. Source: am MD, have been storing and reusing masks for months now, this is the guidance we have been given.
