Water filter straw

A water filter straw is a portable filtration device that allows users to drink directly from natural water sources by filtering out contaminants like bacteria, parasites, and microplastics. The straw uses built-in filtration technology, typically consisting of activated carbon and membrane filters, to make water safe for consumption in outdoor or emergency settings. It is popular among hikers, campers, and survivalists who need a lightweight and convenient solution for accessing clean drinking water in remote areas.
