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

The upgraded water filter has a larger filtration capacity of 5,000 liters (compared to 1,500 liters before) and a faster water flow rate. To drink the filtered water quickly, first stand the dry filter up 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 place it to dry. To extend the straw filter's lifetime, always use the best fresh water source to backwash it after each use. Remember, 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, such as pollution, odor, chlorine, and organic chemicals, while ensuring the water's essential mineral balance remains untouched.

With a pore size of 0.1 microns, our water purifier straw can filter out 99.99999% of harmful particles, maintaining an optimum flow rate of 16.9 fl oz/min (500 ml/min) and high filtration accuracy. Made of durable, food-grade, BPA-free plastics, our water filters have a smaller frame and more convenient, versatile filtering modes, making them ideal for connecting to soft water pouches, disposable water bottles, or using as a replacement gravity filter.

Membrane Solutions offers a range of water filtration products to suit your needs, including the Upgrade Filter Straw, Squeezable Filtration Kit, WS02 Water Filter Straw, Gravity Water Filter Pro, U3P Gravity Water System, and RV Water Filter.
