Ideal for large groups, the GravityWorks 4.0L Water Filter System eliminates the worry of having an adequate water supply on the trail, no matter how many people you're traveling with. With its 8-liter capacity, you can haul up to 4-liters in the clean reservoir and 4-liters in the dirty reservoir, plus it filters in less than 2.5 minutes to ensure you always have safe, clean drinking water close at hand. Reservoirs have been treated with SlimeGuard to prevent the growth of harmful bacteria. The clean reservoir disconnects for easy dispensing. GravityWorks filters meet all EPA and NSF guidelines for the removal of bacteria and protozoa, including giardia, cryptosporidium, e. coli, salmonella and cholera. Backflush feature works in four seconds and requires no additional tools. The clean-storage reservoir sports a convenient shutoff clamp for quick and easy water dispensing. Clip webbing for hanging.
