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.

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".

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.

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.

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.
