Our verdict

A light, fast flowing filter for hikers who refill standard threaded bottles from streams. Virus and chemical removal are not claimed, so doubtful water still needs another treatment.

Overview

Hikers and travelers get a pocket membrane microfilter that screws onto a standard water bottle. Water passes through the membrane, which strips out bacteria, parasites and microplastics before you drink.

Flow is the strong suit here: a full bottle passes through in well under a minute, and the membrane is built to resist clogging from sand and silt. Protection stops at biological threats and microplastics, so chemical or viral contamination calls for a separate method.

Who it's for

Backpackers, travelers and emergency kits that depend on refilling from open water or doubtful taps. People who need virus protection or a group gravity system should look at a different design.

Pros and cons

Pros
  • Screws onto standard bottle threads
  • Very light in a pack
  • Fast flow through the membrane
  • Long membrane life
Cons
  • Virus removal not listed
  • No chemical or taste reduction claimed
  • Needs a compatible bottle to work

Performance notes

Flow depends on the membrane staying clear, and fine silt is what usually slows a filter like this. The enhanced membrane is designed to shed that buildup, which holds the flow up over a long trip. Thread fit decides whether it works with your bottle at all.
