ClarisFlow: An Outdoor Water Filter for Bottles and Squeeze Bags

The ClarisFlow outdoor water filter is built around a 0.01 micron hollow-fiber membrane. It is made for campers, hikers, and trail travelers who draw from freshwater sources such as rivers, lakes, and streams.

A dual-threaded 28mm connector sits on both ends, so it screws onto standard bottles and squeeze bags. It can also be used by sipping straight through the mouthpiece. The body uses BPA-free, food-grade materials, and a protective dust cap is included.

As a portable water filter system, it travels easily with other trail gear. Among hiking water filters, it is shaped for simple bottle and bag setups, and as a portable water filter for camping it needs no extra parts. Anyone choosing an outdoor water filtration system will find these basics:

  • 0.01 micron hollow-fiber membrane
  • 28mm threads on both ends
  • BPA-free, food-grade materials
  • Protective dust cap included
