manager for help selecting the initial size to try.

4. If the respirator does not pass the negative pressure seal test or feels uncomfortable, try the next nearest size relative to

fit test to verify the size. If the respirator passes a negative pressure seal test but does NOT pass a respirator fit test, try
the next nearest size.
