Katadyn BeFree AC Filter Roll-Up Bottle 1 l - Slate Blue

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 a precision of 0.1 micron (0.0001 mm) effectively eliminates bacteria, protozoa, cysts, chemicals, and microplastics. The filter's efficiency allows filtering up to 1000 liters - depending on the source quality - with a flow rate of up to 2 liters per minute.
• Stage 2 - responsible for chlorine reduction, unpleasant odor limitation, and taste improvement thanks to the replaceable activated carbon cartridge. Its efficiency is up to 200 liters.

The BeFree EZ-Clean membrane is designed for quick and convenient cleaning without the need for additional tools or backwashing. To clean the filter, simply shake it or rinse it with water. This solution significantly facilitates usage during field trips and shortens the time needed for maintenance of the filtration system.

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 you to extend the cartridge's lifespan and better adapt filtration to current conditions.

The bottle is made of flexible material in Slate Blue color, allowing it to be rolled up after emptying. This way, it takes up less space during transport and can be conveniently carried in a backpack, bag, or jacket pocket. The model is equipped with a durable handle, allowing for attachment and hanging on equipment.

Silicone mouthpiece secured with a tight cap protecting against dirt. The design also allows for easy removal of the mouthpiece for cleaning or replacement. The bottle's body features a practical measuring scale, which facilitates controlling the amount of liquids.
