The Water Filter is a lightweight, compact water purifier with a high filtration capacity of only 145.8g. The main body that covers the filter is a pump, and water can be purified just by grasping it. Since you can drink directly while purifying water, you can get water from a small puddle. Of course, you can also inject water into the bottle. The hollow fiber membrane filter has a water purification capacity of about 1 L per minute, and the life of the filter is about 2,000 L. On-site self-cleaning is possible.
For those who camp in the absence of water, BBQ on the riverbank, of course, for mountaineering, and in case something goes wrong. Because it is lightweight and compact, it does not get in the way and is a water purifier that can be used in all situations.
