Work is full of coughing tourists with no masks and I really need the best protection. I wear 2 x kn-95 but I can feel myself getting sick with something mild

KN95s don't seal very well at all on many people because they use earloops. Earloops just don't give you enough pressure to get a real good seal. They still help but they're probably inferior on your face to a good headloop N95. I'd recommend the 3M Aura. It fits a lot of people very well. Also, it's not recommended to double mask with a medical respirator. Doing so can deform the seal and doubling up on the filtration layer is not necessary.
Seconding the 3M Auras. They're reasonably comfortable and you can get them in packs of 20 on amazon.
