    Best water filter system on

    Best water filter system on the market. Highly recommend having in your bag for your next adventure.

    Works, but dirty bag closure is moronic

    6 days ago
    Great filter, though I use it in backcountry that has relatively clear water (doesn't clog the filter). Main gripe is the closure system for "Dirty" bag. It's printed on the bag "Zip shut to secure. Invert to test. " This is the worst advice ever. I posit it is nearly impossible to zip this bag, invert it and have the water remain within. I use this bag canoeing, I paddle out to the middle of the lake for water and I have to strap the bag to my leg after filling and have the bag hang from my leg until I return to shore and then have to struggle to get out of the tippy solo canoe while keeping the bag from spilling. I don't understand why one would pretend that it is possible to zip this bag closed and have it hold the water within. I dare the engineer that developed this system and printed the instruction on said bag to fill it with water, zip it closed and invert it over his laptop.

    Awesome filter for groups and super easy to back flush. I love seeing the dirty water transition into the clean bag. I would 100% recommend.

    Had high expectations from reviews, which is not always a good place to start, and came from using tablets not any other filters so I don't know how bad others can be, but overall a good experience. Don't love the ziplock closure (maybe roll top would be better?)

    Yes, I recommend this product.

    Super easy. Was a hit on our trip whwn others had pumps

    This is the easiest and quickest water filtration system I've used. Four of us biked to Goldmyer Hotsprings for a few days and this kept all of our water bottles filled and cooking was a breeze with this easy system of using gravity.

    Never Pump Again!

    We've had our 4L GravityWorks system for seven years now (still on the original filter!) and will never consider going back to a pump system. Our typical use is in the Boundary Waters and Ontario's Quetico Provincial Park on 10-day trips. On our last portage before our destination lake for the night we pull the dirty water reservoir out of the storage bag, paddle to the middle of the lake, scoop up four liters of water, then head for a campsite. Before setting up the tent, we hang the gravity filter and we have clean water before gear is in the tent! With proper backflushes, air purges, and cleaning/drying before storage, slow filtration has never been an issue. Only one problem: the black 'cleanside cap' disappeared on our recent Quetico trip. Where do I get a replacement? And shouldn't it be a brighter color?

    Season 2: Disappointed

    2 years ago
    Used on first trip - year one, worked very well (filter was new)... year two the filter was nearly at a stand still. Not sure why the filter failed after one trip - it was backwashed and stored as per guidelines, and used in pretty clean water on the first trip. Expensive filter for a single use. Maybe go back to MSR pump filter? At least the MSR filter was reliable.
