How Effective are Backflushing and Storage Practices for Backcountry Squeeze Filters Using Hollow-Fiber Membrane Technology?
We provide data that evaluates backflushing and storage in maintaining flow rates of the Platypus Quickdraw, Sawyer Squeeze, and Katadyn Befree hollow-fiber membrane squeeze filters.
The purpose of this article is to present three ultralight water treatment options for backpacking. We chose these three for their diversity and efficacy, and they include a chemical method, a physical method, and an electro-ultraviolet method. We included a video to demonstrate each technology in the field.
