Comparison of mask standard, ratings and filtration effectiveness

 

3M, FFP1, N95, KN95? What do mask numbers and letters mean?

The ratings cover (most importantly for us) the filtration level, among other things. You can think of them like G, PG, PG-13, R ratings for movies. The movie ratings cover who can watch them.

EN 149:2001+A1:2009 / ASTM F2100 / NIOSH

These are standards for masks. They specify the rules and testing methods companies should follow to rate their masks. These standards define the N95, FFP1, and FFP2 ratings above. Using the movie rating analogy, you can think of it like this: the people reviewing movies and choosing the appropriate movie rating must have a set of rules to decide if the movie is considered PG-13 or R. They’ll follow these rules to rate the movie. These standards are the set of rules for masks.

Why are there so many? Standards labelled “EN” are for the EU. ASTM F2100 (NIOSH) is for the US. Many other countries will have their own rating systems too.

3M masks?

3M is a company that manufactures masks. They generally produce masks that meet KN95 or N95 standards.

PM2.5 vs. N95

As we now know, N95 is a mask rating. PM2.5 refers to “particulate matter” or a fancy way of saying “pollution particles” that are in the air. The 2.5 refers to the size of these particles as being 2.5 microns or smaller.

SINGLE-USE FACE MASK

Single use masks (normally one layer, very thin) are typically only effective at capturing larger dust particles, but can do so fairly well.

 

SURGICAL MASK

Surgical mask standards have higher requirements for capturing virus-sized (0.1 micron) particles, however they vary by region.

RESPIRATOR MASK

Pollution masks (respirators) typically capture >90% of virus-sized particles. This includes ratings such as N95, KN95, FFP1, FFP2 and FFP3.
