N95 is not a specific product name, it is the standard of classification of a mask, which is in the U. S. NIOSH standard 'filter non oily particles efficiency for more than 95%', and through NIOSH ( The national institute for occupational safety and health) Review of masks. In general, the higher filtration efficiency, protective effect is better, but also the breathing resistance. Therefore, N95 is the best balance of protection and comfort, therefore also be an option for most people.
