Membrane Solutions Straw II Water Filter - Dark Blue - Your Guarantee of Safe Water in Any Terrain

The Membrane Solutions Straw II water filter - Dark Blue is an ultra-advanced, compact personal straw-style filter designed for enthusiasts of survival, bushcraft, trekking, and long-distance expeditions. This device is an absolute cornerstone of any survival kit or EDC gear. It lets you forget about problems with access to safe drinking water in the field, allowing you to draw and purify fluids directly from rivers, lakes, streams, and even rainwater without the need for prior boiling.

The reliability and uncompromising effectiveness represented by the Membrane Solutions straw filter are based on an innovative four-stage purification system. The first barrier is a precision strainer that catches mechanical impurities such as silt or sand. The next stage consists of special PP cotton fibers that improve water clarity. The heart of the system is a 0.1-micron Hollow Fiber semi-permeable membrane, which permanently eliminates up to 99.99999% of bacteria and 99.99% of parasites and protozoa. The final stage is a replaceable activated carbon cartridge in a coconut fiber shell, which effectively absorbs heavy metals, chemicals, and chlorine, drastically improving the final taste and odor of the filtered water.

The ergonomics and versatility of the Membrane Solutions Straw II - Dark Blue model make it intuitive to use in extreme conditions. The design features a universal 28mm thread, which allows the filter to be screwed directly onto traditional PET bottles or dedicated hydration bags. The housing, made of lightweight, BPA-free polymer, is highly resistant to cracking. Practical inlet and outlet caps protect the interior from contamination during transport, and the included lanyard prevents loss. Furthermore, the filter is extremely easy to maintain – its long-term use is ensured by a backwashing option using clean water.
