In N-95 respirators, what does the 'N' indicate?

NIOSH filter classifications explain why the letter in N-95 matters: the N indicates the filter is not resistant to oil. This means the respirator is designed for non-oily environments and its performance can degrade in the presence of oil aerosols. There are other ratings—R for somewhat oil resistant and P for oil-proof—that describe oil resistance differently. The number you see (95) refers to the filtration efficiency for non-oil aerosols, but the question specifically asks about what the letter means. It is not about negative pressure, fit, or reusability.
