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 filtering tap water and clean natural water sources, such as streams or creeks. The foldable, reinforced Double-Layer SoftFlask construction makes the model suitable for intensive use in demanding outdoor conditions. 

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

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

• 1st stage - utilizes a Hollow Fiber membrane with an accuracy of 0.1 microns (0.0001 mm), which effectively eliminates bacteria, protozoa, cysts, chemicals, and microplastics. The filter's efficiency allows filtering up to 1000 liters - depending on the quality of the source - with a flow rate reaching up to 2 liters per minute.
• 2nd stage - responsible for reducing chlorine, minimizing unpleasant odors, and improving taste thanks to the use of the replaceable activated carbon cartridge. Its efficiency is up to 200 liters.

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 in water. This solution significantly facilitates use during field trips and reduces the time needed for system maintenance.

Activated carbon cartridge can be easily replaced or removed in situations where taste improvement is not necessary, e.g., when using clean mountain sources. This allows you to extend the cartridge's lifespan and better adapt the filtration method 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 very little 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 nozzle is protected by a tight cap preventing dirt. The design also allows for easy disassembly of the nozzle for cleaning or replacement. The bottle's body features a practical measurement indicator that facilitates monitoring fluid levels.
