    I've used three different purifiers and this one is my favorite from a water taste and ease of use standpoint. The safety valve is a nice feature--when the filter begins to clog causing water pressure to be too high when pumping, the valve allows the water to release. This serves as an indicator for filter cleaning--more importantly, if water is NOT squirting out the valve there is no need to clean the filter. Doing so wears out the filter prematurely. The instructions included some practical tips such as 1) don't attach the translucent, outgoing tube when you use for the first time because the charcoal-colored water that comes out initially can stain it; 2) if you drop the filter, the water may come out charcoal colored so be sure to clear; 3) pump with the safety valve facing away from you or you may get wet; 4) don't over-clean the filter or you'll wear out unnecessarily; and 5) the filter may take on the texture of 'lizard skin'--not to worry, this is normal (didn't know what that meant until I saw it, and yes, that would have concerned me!) Gives you confidence that the manufacturers has YOU in mind.

    The MSR SweetWater filter worked very well. We used it several times a day to pump about 2-3 liters at a time for a week without any problems. The other filter we had in camp left water that did not taste as good as with the MSR, so after a short time, we only used the MSR. It is not a very fast filter but I am happy to have the compactness & light weight at the expense of taking longer to pump a given amount of water. We did not use the sodium hypochlorite solution since we were mainly concerned about giardia.

    In silty waters without optional the siltstopper filter this thing is intolerable as it clogs up after pumping only several liters of water. It must then be cleaned,which is a bit of a tedious process. In waters with lower silt content and with the optional silt stopper filter it becomes a more viable option but still needs cleaning more often than I'd like. Consequently I am ready to try another brand to see how it compares. Having said that, it has never truly failed me and that is always a good thing.
