Thanks to the compact and lightweight BeFree water bottle with water filter, you don't have to worry about getting clean drinking water on your outdoor adventures. Simply fill the bottle with water on the go and instantly enjoy clean water thanks to the EZ-Clean membrane filter. The filter can be cleaned quickly and easily while you're on the move. The drinking system takes up little space and, at 65 g, is lighter than a smartphone. The drinking bag can be folded up and fits into any pocket, making it ideal for traveling. The EZ-Clean membrane filter guarantees fresh and clean water no matter where you are. Just fill the water bottle with water from a river, stream, or lake, screw the filter on, and you're ready to go. The drinking opening keeps coarse dirt away, and the filter removes harmful microorganisms, ensuring you only consume clean water. The water flow rate is 1 liter per minute, so you can quench your thirst quickly and easily. The filter fits all Hydrapak SoftFlask bottles from Katadyn and can also be cleaned quickly and easily. Thanks to the open filter cartridge, the EZ-Clean membrane does not require backwashing during cleaning. You have two options for cleaning: first, fill the container with water, close it with the lid, and shake it vigorously a few times; second, remove the filter and swirl it a few times in lake or river water. Both options are ideal for traveling. However, do not hold it horizontally under running water, as this could damage the hollow fiber membrane and render the filter ineffective. The Hydrapak SoftFlask drinking bottle is the ideal companion on the road. At 65 g, it is ultra-lightweight and can be folded small enough to fit into any pocket. The bottle is 100% BPA- and PVC-free, robust, durable, and should not be missing from any backpacking equipment.
