If unused and stored in a protected environment with moderate temperature and low ozone, our personal water filter straw will be indefinite. Our upgraded straw can connect to disposable water bottles with 28mm threading, functioning as a squeezable water filtration system and as a replacement filter of different gravity systems, including our 6L gravity system "B08ZYMXLMH".

Our upgraded water filter straw has a larger filtration capacity of 5,000 L, an improvement from the previous capacity of 1,500 liters, and its water flow rate is also faster. To drink filtering water quickly, simply stand the Water 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 with clean water and store vertically to dry.

For use with the straw water filter, we recommend that you always use the best fresh water source to backwash after each use. Note that our products do not work for seawater.
