The four-litre GravityWorks Filter from Platypus is an ideal solution to providing clean drinking water for groups or basecamps. By using the natural force of gravity, Platypus have done away with moving parts and allowed you to go about setting up camp as the water is filtered hands-free.

The kit comes complete with two water reservoirs, one clearly labelled for dirty water and the other for clean, and a filter that attaches between the two. With the full dirty reservoir hung higher than the empty clean one, gravity does the work for you as the water passes through the filter and into the clean reservoir.

Cleaning the filter is easy, simply raising the clean bladder higher than the dirty one forces water back through the filter clearing the pores in the hollow fibre filter and restoring flow to your system.

This kit comes complete with a shut-off clamp, so you can detach the clean bladder mod-filtration, and all of this packs neatly away in the included storage sack.
