When the strap breaks
You'll only be getting symbolic protection long before the strap breaks.
It's not symbolic. It's less than 95 percent of particles at the threshold size, but dont pretend like it's the same as nothing.
I mean to say that a second-, third-, or fourth-day N95, snapped strap or no, will no longer be filtering 95% of the particles, giving a false sense of confidence.
Did not mean to say that N95s are just symbolic, but I understand how it could be read that way.
It doesn't stop working because you wear it. Why should it? Have some masks on rotation and leave the ones you aren't wearing in the sun or in a UV-C decontamination box.
