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 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 6L gravity system "B08ZYMXLMH".

The upgrade to the water filter straw includes a larger filtration capacity of 5,000 liters (increased from 1,500 liters), as well as a faster water flow rate. To drink the filtered water quickly, first stand the dry water filter in drinking water for 1-2 minutes or rinse the mouthpiece side under a tap until the inside is wet. After each use, backwash with clean water and vertically position the straw to dry.

To extend the lifetime of the straw water filter, we suggest always using the best fresh water source to backwash the filter after each use. Please note that the filter does not work for seawater, and it's important to remember to dry and store it properly.

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 system 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.

Compared to the 0.2-micron water purifier straws on the market, our 0.1-micron pore size water purifier straw maintains an optimum flow rate of 16.9 fl oz/min (500 ml/min) while providing high filtration accuracy. The straw is made of durable, food-grade, BPA-free plastics, ensuring safe and quality drinking water.

Membrane Solutions water filters have a smaller frame and more convenient, versatile filtering modes, making them ideal for connecting with a soft water pouch or disposable water bottle, and even as a replacement gravity filter to get pure water for family and group use.
