Before your filter, prefilter.

Well this filter may have its place but we tested
in 2008 at glacier . We talked to the MSR rep.
at the California outdoor show and he went through
the steps of backwashing the unit. Well we could not get the filter to backwasher at all, and after 3 days it was clogged.
It may be light but I'am not interested in taking the unit apart to switch the valves for back washing.
After returning from Glacier I called the rep. and he said they had some bad filter cartridges .
I'am going to continue to carry my 15 oz. First need water filter that has never failed yet.

it's great. the hyperflow is awesome. it's light and super fast at pumping mass quantities of water. this replacement works great, just like the brand new one you got with the filter. it makes it so the filter can do it's job on the other nasties and not worry about the swampy muck.
