The HyperFlow utilizes the latest Hollow Fiber Technology in a package so small and so easy to use it will change the way you travel in the backcountry. Its ergonomic design, diminutive size and tool-free maintainability make it just as appropriate on day trips as it is on multi-day excursions. Also included is a Quick Connect Bottle Adapter - allowing direct connection to all MSR hydration products and a variety of other "wide mouth" containers - and an advanced prefilter to prolong the life of your filter.
Great filter
I have used this filter in the field for months and it is my favorite - it is small, light and fast. I own 3 others from various manufacturers and keep grabbing this one.
Back flushing is not to hard once you've done it a time or two.
Manufacturer Comments
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.
Please also check www.msrgear.com for improved MSR HyperFlow microfilter instructions and an instructional video on proper back flushing of the unit.
DO NOT BUY THIS PUMP
Three of us bought this pump thinking what a great high volume pump it was. It was great for the first 4-6 liters. After that it went downhill fast. Even after the crazy back flushing exercise it was poor, and finally after 8-10 liters became unusable for all of us. Thank goodness for one of our other hikers who had another brand to use. DO NOT BUY THIS PUMP until or unless MSR can provide and explanation to the many reviews I have now since seen that say the same thing!
