Thanks to the compact and lightweight BeFree water bottle with water filter, you no longer have to worry about clean drinking water during your outdoor adventures. Simply fill the bottle with water on the go and enjoy clean water instantly, thanks to the EZ-Clean membrane filter. The filter can be quickly and easily cleaned while you're on the move. The drinking system takes up little space and weighs only 65 g, less than a smartphone. The drinking pouch can be folded and fits into any bag, making it ideal for travel. 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 on the filter, and you're ready to go. The drinking opening keeps large contaminants out, and the filter removes harmful microorganisms, ensuring you only consume clean water. The flow rate is 1 liter per minute, allowing you to 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 backflushing during cleaning. You have two cleaning options: first, fill the container with water, close it with the lid, and shake it vigorously a few times; second, remove the filter and swish it a few times in the water of a lake or river. Both options are ideal for travel. 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 perfect companion for travel. Weighing just 65 g, it is ultralight and can be folded down small enough to fit in any bag. The bottle is 100% BPA and PVC free, sturdy, durable, and should be an essential part of any backpacking gear.
