provided you have the correct type of mask and you're using it correctly, they last much longer and even disposable masks can be reused. the function of a mask is only to catch particles that the virus might be on.

today i learned that masks either have ammunition or batteries.

Rule of thumb the govt here told us: you can wear a reusable mask for about 4 hours straight before the humidity from your breath lower its efficiency.
