Links to other FFR filter classes

FFRs are air-purifying respirators that protect by filtering particles out of the air the user is breathing. There are seven classes of FFR filters, though not all have active approvals at this time.

  • - Filters at least 99% of airborne particles. Not resistant to oil.
  • - Filters at least 99.97% of airborne particles. Not resistant to oil.
  • - Filters at least 95% of airborne particles. Somewhat resistant to oil.
  • - Filters at least 95% of airborne particles. Strongly resistant to oil.
  • - Filters at least 99.97% of airborne particles. Strongly resistant to oil.

Ninety-five percent is the minimal level of filtration that NIOSH will approve. For more information about types of FFRs and protection levels, see the link below.

Best practices

For your FFR to work as effectively as possible, you must wear it correctly. This includes the process of putting it on (donning) and taking it off (doffing).

For donning instructions specific to the make and model of FFR you are using, see the donning instructions in or on the packaging of your respirator. If you do not have access to these instructions, please see the respirator approval holder (manufacturer) or private label entity website or contact the approval holder directly.

For generalized donning instructions, refer to the NIOSH Infographic below.
