Membrane Solutions Straw II Water Filter - Dark Blue

A lightweight and compact water filter with a 4-stage purification system, enabling filtration of up to 5000 litres of water. It effectively removes bacteria, protozoa, microplastics, and mechanical impurities, allowing you to drink water directly from natural sources.

The Straw II model uses an advanced four-stage purification system that eliminates various impurities in the water. The design is based on a 0.1-micron Hollow Fiber membrane, which effectively blocks bacteria and protozoa. The filtration process starts with a layer for preliminary removal of mechanical particles, followed by a filter made of PP cotton fibres to improve water clarity. Next is the membrane that reduces most microorganisms, and the final stage is a activated carbon filter that improves taste and neutralises unpleasant odours. This construction effectively handles even difficult impurities, providing the user with clean and safe water.

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

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

The filter enables purification of up to 5000 litres of water. The water flow reaches a speed of approximately half a litre per minute, providing comfortable drinking without noticeable resistance.
