How to purify water when camping?

Boiling water is a surefire way to kill bacteria, viruses and protozoa in the water that can make you sick. But if it is not convenient for you to boil water outdoors, a water filter straw would be a perfect way to purify water when camping. It usually doesn’t take much space in your backpacking, but could remove most of the harmful substances from the outdoor water source like river, stream and etc.

What is a portable water filter straw?

Portable water filter straw is a kind of filter in a small size, which could help you drink water directly from the outdoor water source just like from a straw. It usually uses active carbon or active charcoal-based systems (and in some cases, there are unique other systems in place), so that it can reduce harmful bacteria and viruses from water. Their primary use is for cleaning water found in nature, allowing you to drink it and cook with it when you're out in the wilderness.

What is the working principle of this Waterdrop portable water filtration system?

Waterdrop filter straw adopts a 0.1-micron hollow fiber membrane, which could prevent protozoa from going through the outer walls of the tubes, while water can easily pass through them. The principle of micro-fibrous tubes is similar to that of medical dialysis technology. Therefore, water going through the filter straw will be clean and safe.

Which kind of bottle can be used with the filter straw?

The filter straw 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.

Can I use this camping water filter to filter saline water?

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

What should you pay attention to after using Waterdrop portable water purifier?

Backwashing is essential for keeping the water filter straw in good condition and making it easy to be used for multiple times.
Do not use chemicals to clean the filter straw because they will shorten the service life of the carbon fiber filter.

How to wash portable water filter straws after use?

Generally, how to wash a portable water filter after use? 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.
But, what if you use Waterdrop camping portable water filter？In addition to the general cleaning method mentioned above, our collapsible water pouch and Gravity Water Bag can be used, or a pop bottle with a standard thread diameter of 27.5 mm can be filled with clean water to backwash the portable water filter.

I have used the water filter straw only once and it no longer works, why?

If the straw is not cleaned up after use, the filter element will be blocked. It should be repeatedly backwashed to remove impurities on the surface of the ultra-filtration membrane.

Why is there a peculiar smell in the second use of my portable water filter straw?

After use, dirty residues are left in the filter element. Please backwash the filter straw to remove dirty impurities on the surface of the filtration membrane. Each time before using, it should be backwashed to avoid a peculiar smell.
