How to backwash the Filterstraw?

After drinking, blow air through the mouthpiece frequently, or drain the water filter straw by shaking out as much water as you can. After using, remove the mouthpiece, and flush it with clean water. Cap the filter tightly after it has dried.

Can I use this Filterstraw to filter saline water?

No, the Filterstraw should be used to filter fresh water rather than saline water.

Which kind of bottle can be used with the Filterstraw?

The Filterstraw can be used with pop bottles that have a thread diameter of 27.5 mm. Therefore, to avoid leakage, it can be matched only with a mineral water bottle that has a thread diameter of 27.5 mm
