Waterdrop Water Filter Straw with Gravity Water Bag, Portable Camping Filtration System, Drinking Water Purifier for Emergency Hiking Travel Backpacking : Sports & Outdoors

Description

It uses four-stage filtration, removing contaminants—from large particles to extremely tiny particles effectively to ensure the safety of the water. Uses advanced Japanese activated carbon fiber filter media to ensure water safety and improve taste, providing you with high-quality water in the field. The filter adopts a 0.1-micron hollow fiber membrane to remove 99.99% of harmful substance in water. You can use the Filterstraw with water bottles or soda bottles that have a standard thread on their tops. Fill the filtered water into the bottle and take it with you anywhere you want. Filterstraw can connect to water bags or bottles, and you can enjoy clean water for yourself and with friends. There is no need for extra syringe backwashing. It eliminates extra cumbersome fittings and makes the water bag versatile. How to backwash Backwashing is essential for keeping the Filterstraw in good condition and making it easy to use multiple times. After drinking, blow air through the mouthpiece frequently, or drain the Filterstraw by shaking out as much water as you can. After using, remove the mouthpiece and flush it with clean water. (A standard water bag can be used, or a pop bottle with a standard thread diameter of 27.5mm can be filled with clean water to backwash the Filterstraw.) Cap the filter tightly after it has dried. Note: Do not use chemicals to clean the Filterstraw because they will shorten the service life of the carbon fiber filter. Working principle There are many micro-fibrous tubes in the 0.1-micron hollow fiber filters. They can 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 Filterstraw will be clean and safe.
