MSR HyperFlow Microfilter

Item #CAS0471 | 71 in Stock
4 Star Rating

I wonder..

By Ranked #55 - Water Filters December 16, 2008

The bad reviewers mostly are saying how good it worked at first, how fast and effective it is. But then say the next day how slow it is..I wonder if they read the directions or if theirs really were defective. This small filter is suppose to be 'back flushed' every 8 liters, that's very often, especially these people saying they used it for groups or 3-12. this shows how to do it, for those you already own and haven't read the directions properly.

for those whose really 'sucks' that's a bummer.

I was shocked to see bad reviews, then I noticed the comment "MSR has identified and fixed a flow rate issue affecting some cartridges in MSR HyperFlow microfilters. As of February 11, 2009, all filter cartridges sold by [this retailer] perform to flow specifications." So if you have a flow rate issue, contact MSR. This little gem has worked flawlessly for me for a few years now. I do the back-flushing maintenance as instructed. Tip: I also carry chlorine tabs as a backup.
