A handy replacement part for the Guardian filter, if you ever manage to wear yours out.

MSR says:

If your Guardian prefilter becomes worn or damaged, this replacement helps extend the life of your purifier. Easy to install, it’s designed to self-right and draw water from just below the surface, where the water is cleanest. Includes prefilter and float.


The range of spares for the MSR Guardian is very impressive, if you do start to wear your Guardian filter out, which is unlikely as it is practically bomb-proof, you can very easily swap out and renew parts to keep it going for years to come.
