Meet the Membrane Solutions Gravity Water Filter and Straw

Have you been dreaming about a water filter that can do it all? The Membrane Solutions Gravity Water Filter and Straw is a dual-use water filtration system. It can serve as a standalone straw filter for drinking straight from the source on lightweight backpacking trips, or you can connect it to the supplied 6-liter reservoir for bulk filtration in groups or at camp. It’s great to have this type of versatility.

This water filter system consists of a large bladder that you can strap onto a tree, car, or anything else. The bladder connects to a filter and allows for gravity to assist in moving water quickly through that filter and into a clean vessel of your choice. You can screw on bottles of the appropriate diameter or just allow the filter to drain into a secondary bladder.

The bladder itself is constructed well and doesn’t reek of plastic, which is a welcome surprise — this can be an issue with some new water filtration systems and bladders, but not here. The filter straw beats out much of the competition by offering a 0.1-micron pore size. What does that mean? The smaller pore size ensures that all bacteria are filtered out effectively.

Backpackers especially will enjoy the utility of this filter as it allows you to use just the straw alone for your personal hydration needs — simply insert the filter end into a body of water and drink through the straw end. There’s nothing better than some fresh and clean water from an alpine brook or stream.
