A properly fit-tested full-face APR carries APF 50 — five times the APF 10 of a half-mask. If your hazard assessment documents concentrations between 10× and 50× OEL, a full-face is required by OSHA. Additionally, the polycarbonate lens protects eyes from splash and mist in corrosive chemical environments, eliminating the need for separate chemical goggles in many situations. For environments ≤ 10× OEL where eye protection is not required, a North half-mask (\u003ca href=\"\/collections\/honeywell-north-half-mask-respirator\" style=\"color:#4fc3f7;text-decoration:underline;\"\u003e7700 or 5500 series →\u003c\/a\u003e) provides the same North bayonet cartridge access at lower cost.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-bottom:6px;\"\u003eCan I use 3M cartridges on the North 54001?\u003c\/h3\u003e\n\u003cp style=\"margin-top:0;\"\u003eNo. The North 54001 uses the North bayonet twist-lock connection, which is incompatible with 3M, MSA, or Moldex cartridges.
