I have used it only once and it no longer works, why?
The product is not cleaned up after use, as a result its filter element is blocked. It should be
repeatedly backwashed to remove impurities on the surface of the ultrafiltration membrane.
Why is there peculiar smell in second use?
After use, dirty residues are left in filter element. Please backwash the filterstraw to remove dirty
impurities on the surface of the filtration membrane. Each time before using, the water filter straw
should be backwashed to avoid peculiar smell.
Can I use this filterstraw to filter saline water?
No, the filterstraw can be used to filter fresh water rather than saline water.
Which kind of bottle can be matched with the filterstraw?
The filterstraw is matched with pop bottle with thread diameter of 27.5 mm in design, and therefore it
can only be matched with mineral water bottle with thread diameter of 27.5 mm to avoid any leakage.
