Filtering up to 1.75 liters a minute without any pumping, the high-capacity GravityWorks Water Filter System filter is one of the easiest and fastest ways to get filtered water in the backcountry.

With two different sizes—6.0L & 4.0L—the GravityWorks is ideal for bigger backpacking groups or basecamps. Offering an 8 or 12 liter total capacity, either model easily supplies filtered water for drinking, washing up, cooking, and cleaning.

  • Fast: Filters up to 1.75 liters per minute; microfilter lifetime up to 1,500 liters of water.

  • Light & Compact: System weighs 11.5 oz. (326 g) and stows smaller than most 1L bottles.
  • Group-ready: 8 or 14 liter (4.0L/6.0L filtered + 4.0L/6.0L unfiltered) total capacity easily supplies water for groups.
  • Field-cleanable: Microfilter can be easily backflushed in 4 seconds to maintain filter performance.
  • Hollow Fiber Advantage: Hundreds of tiny, hollow fibers enable the microfilter to filter water faster than traditional filter media.
