Overview
Squeezing water from a pouch through a hollow fiber membrane traps bacteria, protozoa and microplastics on the outside of the fibers while clean water passes through the center. The kit adds a straw and a hydration pack adapter, and the filter can be backwashed.
A light, small filter that connects to pouches, bottles and hydration packs is the reason to carry it into the backcountry. The limitation is the listing text, which disagrees with itself on a few points and gives no thread sizes for bottles.
Who it's for
Backpackers, travelers and people building a preparedness kit can filter from open water sources. Those who need to clear viruses, chemicals or dissolved salt need a different system.
Pros and cons
- Very light and compact
- Hollow fiber membrane filtration
- Works with pouch, straw or hydration pack
- Lifetime warranty on the filter
- Virus removal not listed
- Pouch count differs across the listing
- Bottle thread sizes not given
Performance notes
The membrane fibers physically block particles larger than their pores, so the result depends on keeping the filter clean. Flow slows as the surface loads up, which is where backwashing restores it. Squeezing speed by hand sets how quickly a pouch empties.
