What does 'N', 'P' and 'R' stand for in N 95, P 100?
This means that a P 100 filter rating is better than an N 95 filter rating.
It means that N 95, N 99, N 100, P 95, P 99, P 100 filters are all rated using the same industry standard.
The manufacturer has confirmed that these particulate-only filters have NO EXPIRATION DATE.
Here is some more very important information:
TC-21C-135 is the Approval Number.
A
pproximately 75mm (2.95") thread diameter.
This fits the MSA Comfo, Comfo II and many other respirators.
This filter also fits the Binks
Millennium
3000 series mask 40-141, 40-128, 40-143 and others.
P 100 filters particles and mists containing radionuclides and asbestos.
P 100 is rated to
99.97%. This exceeds N 95 95% mask filtration rating.
These cartridges will not filter out hazardous gases or vapors, only particulates like dirt, asbestos, radioactive materials, etc.
These cartridges are unused, new old stock, from the US Military.
MSA confirms that their
particulate
filters have no expiration date.
If you can draw sufficient air through the
cartridge
without excessive effort, then you can keep using them.
As the pressure drop increases across the filter, the particulate removal
efficiency
will typically
increase with use
