Water, water everywhere but not a drop to drink. That’s an all too familiar problem for those off in the wilds. While there are numerous options for making water drinkable, most are not ideal. But we recently heard about the Platypus GravityWorks Filter, which is essentially a gravity-based or primal pull system that coaxes water through a filter with no actual pumping required.
It is pretty simple actually; basically a few tubes, water bags and a filter cartridge that lets you put in potentially “bad” water in one bag and lets gravity and the filter transform it into “good” – or at least safe to drink – water. The system is fairly speedy, and can filter about 1.75 liters of water per minute. The filter features a pore size of .2 microns, which is enough to eliminate bacteria, protozoa, and other contaminants that may taint fresh water, but it won’t stop viruses so this is something to keep in mind if you’re not sure about the quality of the H2O. But the GravityWorks Filter certainly will do wonders for turning lake or river water in the wilds into something refreshing after a long hike.
