Katadyn BeFree AC Filter Roll-Up Bottle 1 l - Black

Filtering bottle with a 1-liter capacity, equipped with an efficient BeFree EZ-Clean membrane filter, designed for purifying tap water and clean natural water sources, such as streams, creeks, or mountain springs. Thanks to its foldable construction and low weight, the model is well suited for trekking, mountain expeditions, travel, and outdoor activities.

The applied filtration element effectively removes microorganisms, chemicals, and microplastics, while also improving the taste and odor of water, ensuring convenient access to safe drinking water in the field. The flexible construction allows the bottle to be compressed after emptying, making transport easier and reducing the amount of space it occupies in a backpack or gear.

The model uses a 2-stage purification system based on the BeFree EZ-Clean membrane and a replaceable activated carbon cartridge. This solution effectively removes biological contaminants and improves the quality of filtered water:

• Stage 1 - Hollow Fiber membrane with an accuracy of 0.1 micron (0.0001 mm) effectively eliminates bacteria, protozoa, cysts, chemicals, and microplastics. The filter's efficiency allows filtering of up to 1000 litres - depending on the source quality - with a flow rate of up to 2 litres per minute.
• Stage 2 - responsible for chlorine reduction, odour removal, and taste improvement due to the replaceable activated carbon cartridge. Its efficiency is up to 200 litres.

BeFree EZ-Clean membrane is designed for quick and convenient cleaning without the need for additional tools or backflushing. To clean the filter, simply shake it or rinse it with water. This solution greatly facilitates use during field trips and reduces the time needed for filter system maintenance.

The activated carbon cartridge can be easily replaced or removed when taste improvement is not necessary, e.g. when using clean mountain sources. This allows increasing cartridge life and better adapting filtration to current conditions.

The bottle is made of flexible material in black, allowing it to be rolled up after emptying. Thanks to this, it takes up less space during transport and can be conveniently carried in a backpack, bag, or jacket pocket. The reinforced Double-Layer SoftFlask construction makes the bottle suitable for intensive use in demanding outdoor conditions. The model is equipped with a durable handle, allowing it to be attached or hung on gear.

Silicone mouthpiece secured with a tight cap protecting against dirt. The design also allows for easy mouthpiece removal for cleaning or replacement. The bottle body features a practical measurement scale, facilitating liquid quantity control.
