PDF	3M™ Disposable Respirator 1870+ N95 The 1870+ healthcare respirator is designed to help provide respiratory protection for the wearer against certain airborne particles

What is the standard N95 size?
The sizing of N95 is dependent on the model that one is using.
Some of the measurements of an N95 are: small, small/medium, medium, medium/large, and large.
The sizes for N95 are available in multiple size configurations that are variable and are not standardized across different models.
What 3M masks are N95?
3M™ Particulate Respirator 8210, N95 is a disposable particulate respirator that is designed to help provide reliable respiratory protection of at least 95 percent filtration efficiency against certain non-oil based particles.
What size filtration does N95 mask have?
N95 respirators made by different companies were found to have different filtration efficiencies for the most penetrating particle size (0.1 to 0.3 micron), but all were at least 95% efficient at that size for NaCl particles.

N95 respirators help reduce the wearer's inhalation exposure to certain airborne particulates. These respirator filters have been tested and certified by NIOSH to be at least 95% efficient when tested against very “small” particles that are the most difficult size to filter (approximately 0.3 microns).
