Weight: 220 g         2 reviews
The MSR HyperFlow Water Microfilter is MSR's smallest, lightest, and fastest-flowing water filtration system. It makes an unbeatable and award-winning choice for those looking to travel light in the backcountry.

The HyperFlow Microfilter utilises the latest Hollow Fibre Technology and MSR's most advanced engineering to make water treatment so small and easy to use that it will change the way you travel in the wilderness. Its ergonomic design, diminutive size and tool-free maintainability make it just as appropriate on day trips as it is on multi-day excursions.

With a filtration rate of 3 litres per minute, you have the most efficient microfilter ever created. Included with each filter is a Quick Connect bottle adaptor, allowing direct connection to all MSR hydration products (such as their excellent Dromedary Bags) and a variety of other 'wide mouth' containers. Also included is an advanced prefilter, helping to prolong the life of your filter.

  Very fast water flow and fits onto the spout for the Karrimor SF Sabre Tactical Hydration System for direct delivery of clean water. Filled up from some dodgy looking water supplies and no apparent ill effects - so seems to work well!

  Easy to use after a bit of practice. Keep it clean and it's a quick way to clean your water.
