Membrane Solutions Straw I Water Filter - Sky Blue

A lightweight and compact straw water filter equipped with a 2-stage purification system, which allows you to filter up to 5000 liters of water. It removes bacteria, parasites, microplastics, and mechanical impurities. It enables drinking water directly from natural sources. It will prove useful during hiking, camping, survival, bushcraft, and travel where access to safe drinking water may be limited.

The Straw I model uses a 2-stage purification system that eliminates a wide range of contaminants found in water. The design combines a Hollow Fiber membrane with a replaceable carbon filter. The first stage is a Hollow Fiber membrane with a density of 0.1 micron. Its structure traps bacteria, parasites, microplastics, and solid impurities such as silt and sand. The second stage is a carbon filter. It is responsible for the reduction of heavy metals and chemicals, and also improves the taste and smell of the filtered water.

The filter is equipped with a universal thread for bottles with a diameter of 28 mm and practical covers for the filter inlet and outlet. A wrist lanyard is included in the set.

The housing is made of durable BPA-free material. Thanks to its small size and low weight, the filter will easily fit into a backpack or bag compartment.

The filter provides the ability to purify up to 5000 liters of water. The flow rate remains at 450 ml per minute, which allows comfortable and natural drinking without noticeable resistance.
