Replacing the Potassium Permanganate Filter
(KMnO4)
The Potassium Permanganate will expire after prolonged use
and is easy to replace. The small black jar is the KMnO4 filter,
just unscrew the bottom plate of the F-960 unit after removing
the battery cap, unscrew the filter, screw in the replacement
and you’re done! Screw back into place the bottom plate and
finally the battery cap.
