And at $120, the GravityWorks is on the more expensive end of the water filtration spectrum. Furthermore, water retrieval can be a pain if you don’t have a reasonably deep or moving water source (similar to any system that relies on a bag to collect water). This filter is great for large groups, but we’ve enjoyed it on smaller outings too when we could quickly retrieve our day’s water and escape back to our camp to fill individual bottles (the clean bag also functions as water storage).īut compared to some of the more minimalist options below, the Platypus GravityWorks is not a small apparatus, with two bags, a filter, and a bundle of tubing. Gravity does all the work: simply fill up the 4-liter “dirty” reservoir, hang it from a tree branch or boulder, and in just a few minutes you’ll have four liters of clean water to drink. Instead of pumping, this system requires minimal effort, can filter up to four liters of water at once, and boasts a speedy flow rate of 1.75 liters per minute. Without a doubt, the Platypus GravityWorks is one of the most convenient water filters on the market, and it’s become a backpacking staple. What we don’t: Bulky you need a decent water source to fill the bag. What we like: Filters and stores a high quantity of water effortlessly and quickly great for groups.
