The primary difference in a medical mask and an N95 respirator is the tight seal that doesn't allow air around the sides. Unless you are in a high risk aerosolized environment, an N95 is unlikely to give you much additional benefit.
Most medical masks are made of the same material out of China that filters > 95% of infectious particles. If you want extra protection, you can look for masks with an "ASTM Level" that gives additional support that the mask is medical grade.
