Saves Your FilterI bought this to use with my MSR MiniWorks water filter. The MiniWorks (and other ceramic filters) are prone to clogging easily when the water is even slightly silty. Yes, you can take the ceramic filter out, scrape it down, and keep going, but... It is much easier to just swap out one of the small compressed paper filters in this pre-filter (replacements are easily found, are cheap, come in a 3 pack tube and are light weight). Also, every time you scrape down a ceramic filter, you scrape away some of the filter material - if you do this a lot, you will need to replace the filter more often - they are expensive (about $40), so this is a better option. Oh, the "pre-filter" that comes on the MiniWorks? They pretty much only filter out sticks, rocks, etc. This pre-filter will catch the very small silty particles that tend to clog the ceramic filter. I just ordered an MSR Hyperflow and hope/assume it will work with it as well as I plan to continue to use this wonderful time-saver.
