I know that breathing through your nose is generally better than breathing through your mouth for the simple fact that your nose has special follicles that act as a filter. But honestly the eyes and nose are most sensitive to infection and that’s part of the reason people are suggesting masks. It’s to lower the number of mucus membrane vectors for infection.
Op is more likely to get sick, especially if the other sick person isn’t washing their hands and cleaning surfaces they touch, and limiting the amount of time touching their own mucus membranes.
But if you inhale through the mouth as the alternative, you’ll directly track the viral load to the lungs which also had mucus and the viral load would multiply there instead. So take your pick. At least the nasal passage has some defences.

Tons of viruses replicate in your sinuses (like covid), so idk if nose breathing would be the right answer.
Really, flushing out your sinuses after exposure is the best option if you can’t wear a mask.
