The key to a long-lasting filter.

Don’t head into the backcountry to find your Hyperflow filter malfunctioning. Instead, get the MSR Hyperflow Microfilter Maintenance Kit, and know that you’ll enjoy fresh filtered water for miles to come. Change out your mangy old O-rings and valves with this handy kit, and let the fresh, clean water keep flowing through many more trips.

  • Filters 3 liters per minute
  • Quick Connect bottle adapter connects with wide mouth containers and MSR hydration products
  • The Hollow Fiber filter removes bacteria, protozoa, and particles
