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 be used 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 (compared to 1,500 L 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 water filter straw under the tap from the "mouthpiece" side until the inside is wet. After each use, backwash it with clean water and vertically place 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 and should be stored dry.

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) and improve the taste, while ensuring the water's essential mineral balance remains untouched.

The 0.1-micron pore size of our water purifier straw maintains an optimal flow rate (16.9 fl oz/min / 500ml/min) and high filtration accuracy, outperforming the 0.2-micron water purifier straws on the market.

Made of durable, food-grade plastics, our water filters are manufactured with BPA-Free ABS, ensuring safe and quality drinking water. Compared to large filter straws, Membrane Solutions water filters have a smaller frame, are more convenient to use, and offer more filtered modes, making them ideal for connecting with a soft water pouch, disposable water bottle, or as a replacement gravity filter for family and group use.
