Problem
Solution
Not using high
efficiency filters
If high-efficiency class-99 or class-100
filters (P3 for non-USA users) are not
being used on the respirator, you may
never get a high fit factor. Filters such as
class-95, P1 and P2 (for non-USA users)
allow some ambient air particles to get
through and be interpreted as face seal
leakage by the PortaCount Fit Tester.
N O T E
The Model 8048 fit tests lower efficiency
respirators including class-95, P1, and P2
filtering-facepieces (disposables).
Alcohol cartridge is
not tightly inserted or
an O-ring is missing
Make sure the alcohol cartridge is installed
properly and all O-rings are in position.
Starting fit test too
soon after respirator
is donned.
When the respirator is first donned,
ambient air particles are trapped inside.
These particles clear out as the person
breathes. According to all fit testing
protocols, a fit test subject must wait 5
minutes after donning the respirator before
beginning the fit testing exercises.
Sample tubes too
long
No more than a few inches should be
added to the sample tube (use a Tube
Adapter). Longer sample tubes prevent
proper purging between the ambient and
respirator sample.
Leaking respirator
probe or fit test
adapter
Make certain the respirator probe (if used)
or fit test adapter does not leak around the
outside.
PortaCount Fit Tester
sample tube leaks
where attached to
probe or adapter due
to wear
Cut a short piece off the end of the tube to
expose a fresh end.
Hair interfering with
face seal
Make sure there is no hair between the
respirator face seal and the individual's
skin.
