    MSR Hyperflow Microfilter Water Filter

    I used this filter over six months of almost weekly backpacking but only in flowing water. Filtered 16 liters of snow melt for our climbing party of 12 in less than 30 minutes and hassle-free. The bottle-mount adapter fit most of the 1 liter bottles carried by our team. Fast and easy to use.

    MSR Hyperflow Microfilter Water Filter

    Note from the manufacturer: We have identified a flow performance issue with some of the hollow fiber filter cartridges contained in MSR HyperFlow microfilters. The performance issue DOES NOT affect the product's ability to filter safe drinking water but can be frustrating as the flow rate of the filter may not perform to product specifications. The issue has been rectified and all filter cartridges currently in production for the MSR HyperFlow microfilter perform to flow specifications. It is our goal to provide you with the most innovative and reliable outdoor gear available when you need it most. You can be confident in the efficacy of the hollow fiber filter technology, but if you are experiencing a less-than-expected flow rate on the MSR HyperFlow microfilter right out of the box or after back flushing, we want to know. Please contact our Customer Service Department at Cascade Designs, Inc. by calling 1.800.531.9531, and we will send you a valid replacement filter element at no charge for any filter cartridge manufactured prior to November 11, 2008. Please have your filter cartridge element handy as we will ask for the serial number for our records and manufacture date verification.
