Let gravity do the work. Gravity water filtration is the easiest, most hands-free way to produce clean water in volume — fill the dirty reservoir, hang it, and clean water flows into the clean bag while you set up camp, cook, or rest. No pumping, no squeezing, no standing over a filter. Cana Provisions carries gravity systems built for real use, led by the award-winning Platypus GravityWorks, which filters up to 1.75 liters per minute and keeps clean and dirty water cleanly separated. It's the ideal setup for backpacking groups, basecamps, and preparedness caches where you need to filter a lot of water with minimal effort. Add an activated carbon element to cut chemicals and tastes, keep a backflush syringe on hand to maintain flow, and pair with a chemical disinfection method for virus protection — hollow-fiber filters don't remove viruses on their own.
