Q: What is the shelf life of it?

Our personal water filter straw will be indefinite if unused and stored in a protected environment, moderate temperature, low ozone, etc.

Q: Can be connected gravity bags and disposable water bottles?

Our upgraded straw can not only connect disposable water bottles of 28mm threading as squeezable water filtration system but also as a replacement filter of different gravity systems. Of course, it also applies to our 6L gravity system "B08ZYMXLMH".

Q: What is different from the upgrade of the straw water filter and before?

The upgrade water filter has a larger filtration capacity of 5,000 L (Can only filter 1,500 liters before), and the water flow rate is getting faster.

Q: How to drink filtering water quickly?

1) When Water Filter is dry, stand it up in drinking water for 1-2 mins or rinse the water filter straw under the tap from the "mouthpiece" side, until the inside is wet; 2) After each use, backwash by water, and vertical placement to dry.

Q: How to extend the straw water filter lifetime?

We suggest that you always use the best fresh water source to backwash the straw filter after each use. Note: Be sure to remember dry then storage and doesn't work for seawater.
