Three Stages — One Complete System
DualFlow uses a three-stage system to do what single-layer filters often can’t. A pre-filter blocks larger debris, a 0.1μm PES hollow fiber membrane physically traps bacteria and parasites, and a silver-loaded activated carbon pack helps reduce odors and improve taste.
Pre-Filter Mesh
Blocks larger particles like sand, silt, and algae before they reach the membrane—helping maintain flow and extend filter life in rougher water conditions.
0.1μm PES Hollow Fiber Membrane
Physically traps bacteria, parasites, and other microorganisms that cannot pass through the membrane pores.
Silver-Loaded Activated Carbon
Helps reduce odor and off-flavors while improving the overall drinking experience. Its modified porous structure is also designed for longer-lasting performance and lower clogging risk.

Backflush Without the Extra Hassle
Simple maintenance means less friction on the trail and fewer reasons to leave the filter behind
Backflushing helps restore flow and extend the usable life of the membrane. With DualFlow, the interface is built in—so there is no need for separate adapters or small extra parts that are easy to lose outdoors.

2L/min Flow, Without the Wait
Flow rate is one of the biggest pain points in outdoor filters. DualFlow uses a homogenized 0.1μm hollow fiber structure to improve output, so clean water comes through quickly with either light pressure or gravity-fed use.
64g and Ready for More Bottles
64g Weight
Light enough to disappear into a fast-moving kit.
28mm + 42mm Fit
Works across narrow-mouth and wide-mouth setups.
Bottle-Friendly Design
Fits standard 28mm plastic bottles like everyday drink bottles.
Built for Safer, More Reliable Use
Safer Silver-Based Carbon Technology
Designed to support odor reduction and filtration performance while avoiding the kind of heavy silver release associated with traditional ion-leaching approaches.
High-Frequency Welded Construction
The filter bucket and 42mm interface use a high-frequency welding process to help prevent leakage and improve structural integrity.
Antibacterial Materials
The housing uses antibacterial ABS to help reduce the risk of residue-related bacterial or algae buildup after use.
Air Particle Inspection on Every Unit
Every filter goes through air particle inspection before leaving the factory to verify membrane integrity and sealing reliability.
