Our personal water filter straw will have an indefinite shelf life if unused and stored in a protected environment with moderate temperature and low ozone. The upgraded straw can not only connect to disposable water bottles with 28mm threading as a squeezable water filtration system, but also serve as a replacement filter for different gravity systems, including our 6L gravity system "B08ZYMXLMH".

The upgraded water filter has a larger filtration capacity of 5,000 L (up from 1,500 L previously), and a faster water flow rate. To drink the filtered water quickly, stand the dry water filter in drinking water for 1-2 minutes or rinse the mouthpiece under a tap until the inside is wet. After each use, backwash with clean water and vertically position it to dry. To extend the straw water filter's lifetime, we suggest always using the best fresh water source to backwash the straw filter after each use. Note that it does not work for seawater.

Our Upgrade 5-Stage Filtration System includes a coarse filter screen, double layer pp cotton fiber, coconut shell activated carbon, and hollow fiber ultrafiltration membranes. This can remove 99.99999% of harmful substances (pollution, odor, chlorine and organic chemicals, etc.) and improve the taste, while ensuring the water's essential mineral balance remains untouched. With a pore size of 0.1 microns, our water purifier straw maintains an optimal flow rate (16.9 fl oz/min / 500ml/min) and high filtration accuracy, compared to the 0.2-micron water purifiers on the market.

Made of durable, food-grade BPA-Free ABS plastics, our water filters have a smaller frame and more convenient filtering modes, ideal for connecting with a soft water pouch or disposable water bottle, and even as a replacement gravity filter for family & group use. Whether for recreation, hiking, camping, scouting, travel, or emergency preparedness, this survival gear, SGS certificated and with a Test Report NBF21-004693-01, provides a simple and quick solution for obtaining clean drinking water wherever you go.
