3M cartridge and filter codes: 6001 to 60929, the 2000 Series and 7093 filters, and the Secure Click D-Series

Every 3M reusable-respirator cartridge and filter is identified by a part number whose series tells you the platform and whose digits tell you the protection: 6001 to 6009 are the bayonet gas and vapor cartridges (6001 organic vapor, 6002 acid gas, 6003 organic vapor and acid gas, 6004 ammonia and methylamine, 6005 formaldehyde and organic vapor, 6006 multi-gas, 6007 mercury vapor group), 60921 to 60929 are the same cartridges with a P100 filter built in, the 2000 and 2200 Series and 7093 are bayonet particulate filters, and the D-Series (D8001, D80926, D3091, D9093, D7N11) are the same codes on the Secure Click connection for the HF-800 and FF-800. The NIOSH classes below each part are the 3M Cartridge and Filter Summary's own, and the NIOSH approval label packed with each part names the facepieces it is approved with.

Why the numbers follow a pattern. 3M prints the protection on its summary chart as a row of letter codes (OV, AG, CL, HC, SD, HF, CD, HS, AM, MA, FM, MV, HE) and the part number carries the pattern: the last digit of a 600x bayonet cartridge is the protection family (1 OV, 2 AG, 3 OV/AG, 4 AM/MA, 5 FM/OV, 6 multi-gas, 7 MV group), the 6092x combinations keep that digit and add a P100 filter, and the Secure Click D-Series keeps the digits behind a D (D8001 is the Secure Click 6001; D80926 the Secure Click 60926; D3091 the Secure Click 2091). The 2000 Series filters are particulate only: 2071 and 2078 P95, 2091 and 2291 P100, 2096/2296 and 2097/2297 P100 with nuisance-level acid gas or organic vapor relief, and the 7093 family the hard-case P100 (7093C with hydrogen fluoride). 3M notes that nuisance-level relief and ozone are 3M suggestions for concentrations under the PEL, not NIOSH approval classes (summary notes 2 and 3).

Questions people ask

What does 3M 6001 protect against?

Organic vapor (3M Cartridge and Filter Summary); 60921 is the same with a P100 filter.

What is the difference between 6003 and 60923?

Both are organic vapor and acid gas (chlorine, hydrogen chloride, sulfur dioxide, hydrogen fluoride, chlorine dioxide, hydrogen sulfide on the chart); the 60923 adds a P100 particulate filter in the same housing (3M summary).

What does 2097 add over 2091?

Both are P100; the 2097 and 2297 add nuisance-level organic vapor relief and are 3M recommended for ozone up to 1 ppm for 8 hours, which is not a NIOSH approval (3M 6000 Series user instructions Table 7 notes).

Do the D-Series cartridges fit a 6000 Series facepiece?

No. The D-Series are Secure Click parts for the HF-800 and FF-800; the 6000 Series cartridges and 2000 Series filters are bayonet (3M summary row groups).

Is there an end-of-service-life indicator?

None is stated for any bayonet or Secure Click cartridge in the 3M documents fetched; 3M refers the change schedule to the employer under 29 CFR 1910.134(d)(3)(iii) (6000 Series user instructions).

How long do unopened 3M cartridges keep?

3M: five years from manufacture when stored unopened in the original packaging away from sunlight, humidity and high temperature (3M cartridge and filter guide FAQ).
