What does an APF mean?

Assigned Protection Factor (APF) is the level of protection a respirator can be expected to provide if it is functioning properly and the user is wearing it correctly. APF is scored via a number, allowing users to gage how much contaminant they are expected to inhale while wearing the respirator.

What is assigned protection factor 10?

Assigned Protection Factor. Workplace level of respiratory protection that a respirator or class of respirators is expected to provide to a population of properly fitted and trained users. NOTE For example, an APF of 10 for a respirator means that a user could expect to inhale no more than one tenth of the airborne contaminant present.
