MSR HyperFlow™ Microfilter

Utilising the latest Hollow Fibre Technology and their most advanced engineering, the award winning MSR HyperFlow™ Microfilter is able to make water treatment so small and so easy to use. Compact when not in use and quick to deploy when needed, the HyperFlow™ Microfilter is a good choice whether on a day excursion or multi-day adventure.

With a flow rate of 3 litres per minute (or 1 litre per 20 strokes), this is the most efficient microfilter ever created. Included is an adapter to connect to MSR hydration bottles as well as the ability to connection to smaller bottle tops including disposable water bottles.

Features:

• Testing: Meets NSF protocol P231 for removal of bacteria (99.9999%) and protozoa (99.9%) from beginning to end of filter life in “worst-case” water.
• High Flow Rate: Pumps more than 3 litres per minute or one litre every 20 strokes.
• Ultralight: Just 7.8 oz. (221 g).
• Ultra-small: Just 7x3.5 in. ( 17.8 x 8.3 cm) makes it easy to take along even when space is at a premium.
