Clean drinking water is an absolute luxury! Backpackers and globetrotters know this very well. Great, if you have the Guardian Gravity Purifier by MSR at hand. The water purifier with gravity system provides clean drinking water practically everywhere on earth, for drinking, cooking and hygiene. The Guardian Gravity Purifier offers the ultimate two-stage protection: the activated carbon filter reduces chemicals and flavours while the hollow fibre filter removes viruses, bacteria, protozoa and microplastics with a filtration of 0.02 microns (that's two ten-thousandths of a millimetre).

Many useful features make it easy to use the system anywhere in the world: the 10-litre container can be easily filled at sinks, ponds and wild springs. A universal bottle adapter prevents cross-contamination and the system cleans itself by quickly flushing the system with the integrated flush valve and maintaining the flow. Another practical feature is the end-of-life indicator, which clearly shows that the cartridge needs to be replaced: the filter medium no longer lets water through, so the user is not exposed to harmful pathogens in the first place. In addition, the compact Guardian Gravity Purifier fits easily into hand luggage and smaller backpacks, so it is absolutely suitable for travelling.
