Field Tested: Guzzle H2O Stream Water Filter

Editor’s note: This article was originally published in Overland Journal’s Winter 2020 Issue.


Sustained remote travel typically requires a means of resupplying water stores, with vehicle-based camping, bathing, cooking, and drinking. Why leave that idyllic mountain stream campsite when all you need is a proper volume filter to supply 2-3 gallons per day, per person? Enter Guzzle H2O, a company founded by two professional sailors.

A few things stand out—the first being the durability of the box, a Pelican-style case complete with a lid seal and robust ribbing. All components are visible, including the Flojet pump, UV module, and high-quality, screw-top filter assembly. Quick-connects allow the inlet and outlet hoses to be easily attached, and the push of a button starts the process at 1.1 gallons per minute, powered by the built-in battery. The serviceability of the system also makes owner repair a real possibility.

The filtering process includes a 99.99 percent LED UV pass that kills bacteria, protozoa, and viruses. Then, the carbon block filter removes solids, microplastics, VOCs, and heavy metals. The pump is noticeably quick and pulled a draft from several feet. There are two lengths of outlet hose provided, and hoses are clearly identified to limit cross-contamination. The battery did come unstuck from the side of the case, easily fixed with a mounting bracket or strap (adhesive has since been improved based on our feedback). Some may find the price a bit steep, but it reflects the quality of the filter and components.
