FAQ:

Q: Is the MSR Sweetwater filter any good?

A: The MSR Sweetwater filter is great. I just replaced the one I had been using for 10 years! I only go out 3-4x/year and it was always there and reliable for good water. The end of it’s useful life came on my last trip on the AT.

Q: Is Sweetwater water filter dead?

A: Sweetwater is dead! Long live my Sweetwater! I have used Sweetwater filters for about 25 years. The replacement filter cartridges routinely lasted me 4 to 5 years with extensive use from relatively clean water sources. It is a bit slow, but tough, compact, and effective.

Q: How does the Sweetwater water filter work?

A: The Sweetwater filter handle is the most delicate of the ones we tested. The water flavor remains largely unchanged. Chemicals are removed through the filter, which can make water taste better. The Sweetwater is easy to pump. The noteworthy detail is the handle. It unscrews and detaches so that it can fold up better for more compact storage.

Q: How do you determine when it is time to replace Sweetwater cartridges?

A: How do you determine when it is time to replace a Sweetwater filter cartridge (main filter,not prefilter), other than the obvious when it becomes too clogged to use anymore. Also, do the cartridges have a shelf life? The SweetWater Filter should be replaced after pumping 750 liters of water.
