Filter Features & Tips

------------------------------------------------------------------------

Fast Flow Rate
Fill a 1-liter container in just one minute.

Delivers Fresh Tasting Water
A solid block carbon eliminates odors, improves taste and removes iodine, chlorine and most chemicals and pesticides.

Field Maintainable
If your filter clogs, simply take it apart, clean it, and put it back together. Our new thread stop will keep you from over-tightening the parts.

User-Friendly
Our adapter base lets you screw your MSR filter directly onto wide-mouth Nalgene bottles and all MSR Hydration Bags.

Long Cartridge Life
An inlet foam pre-filter removes large debris, and our patented inlet float keeps the intake hose off the stream bottom, extending the life of your cartridge.

Worry Free
An indicator gauge that lets you know when its time to replace your ceramic cartridge.

AirSpring Accumulator
By using a bubble of trapped air, the AirSpring Accumulator pushes more water through in less time. On the handle down stroke the air bubble is compressed, storing some of the pump force, then on the up stroke, the bubble expands pushing water through the cartridge.

------------------------------------------------------------------------

Tip for Virus Treatment

If you are concerned about viruses, treat the water before or after filtering with a disinfectant such as chlorine or iodine.
