The BeFree Filter AC 0.5L from Katadyn is a practical water filter for anyone who doesn't want to go without clean drinking water when travelling. With its flexible, lightweight design, it fits easily into running waistcoats, rucksacks or jacket pockets - perfect for hiking, cycling, camping or everyday use. The two-stage filter system not only removes microorganisms such as bacteria and protozoa, but also reduces unpleasant odours and flavours. This means that even water from natural sources or public taps can be enjoyed. With a flow rate of up to two litres per minute, fresh water can be obtained quickly. Cleaning the filter is extremely easy: thanks to the EZ-Clean membrane, all you need to do is shake the filter or swirl it in the water to remove deposits. The practical hinged lid protects the drinking opening from dirt and prevents spillages during transport. The filter is BPA-free and has been developed for a long service life. If clean water is already available, the activated carbon filter of the BeFree Filter AC 0.5L can be easily removed to preserve the natural flavour of the water.
