Membrane Solutions Straw II Water Filter - Dark Blue

Lightweight and compact water filter with a 4-stage purification system, allowing you to filter up to 5000 liters of water. Effectively removes bacteria, protozoa, microplastics, and mechanical impurities, enabling you to drink water directly from natural sources.

The Straw II model uses an advanced four-stage purification system to eliminate various contaminants in the water. The design is based on a Hollow Fiber membrane with a density of 0.1 microns, which effectively blocks bacteria and protozoa. The filtration process begins with a layer of pre-removal of mechanical particles, followed by a filter made of PP cotton fibers to improve water clarity. Next is the membrane that reduces most microorganisms, and the final stage is an activated carbon filter that enhances flavor and neutralizes unpleasant odors. This construction effectively handles even tough contaminants, providing the user with clean and safe water.

The filter is equipped with a universal 28 mm bottle thread and practical inlet and outlet covers. The set also includes a wrist lanyard.

The casing is made of durable BPA-free material. Its small size and lightweight design allow for easy storage of the filter in a backpack or bag.

The filter can purify up to 5000 liters of water. The water flow reaches a rate of about half a liter per minute, ensuring comfortable drinking without noticeable resistance.
