Avram,
first are these commercial or medical? commercial are not the right ones.
2nd, one common use of N95 is for people near someone immunocompromised or elderly. In this case, you would need a 2-way protection.
3rd, there are enough people around who use them and also those who should even if they don’t (elderly), and settings where enough people use it, like medical, so you would need to wear/change different masks.
4th, just because many people do not use, doe not mean you should not be courteous towards them.
I understand, though, if you have to sit whole day with Bigbochur and chaverav, you may want to wear big exhaust, dark glasses, and noise-cancelling headphones.
