MUV Tote Gravity Water Filter

(2 reviews) Write a Review

Gravity systems are great ways to filter large amounts of water with very little effort. Simply hang the reservoir with dirty water from a tree. Place the clean water tube into your water bottle or hydration reservoir and let gravity do all of the work. Perfect for backpacking, camping, and setting up a base-camp.

Tote Gravity Water Filter is a gravity filter that uses ultra-filtration membrane with a 0.1 micron pore size which removes virtually all bacteria, E. Coli, Giardia, Cryptosporidium and more. The 10 liter gravity bag is lightweight, durable, and compact. A wide mouth roll-top makes it easy to fill from a stream, river, or lake, and the robust hang strap doubles as a shoulder bag so you can easily carry water.

    No instructions?

    Seems to have worked well (no one got sick). Had no instructions though and came with little filters and no clue what to do with them. Also leaked a bit and had a continuous drip.
