    Katadyn's Gravity Camp 6L Water Filter is definitely the lazy man's filter, but that's only because the lazy man has figured out what the rough-and-tough pump fanatic is still learning: you can get crisp, clear, and clean water without actually having to pump until your arm falls off.

    The Gravity Camp uses a—wait for it—gravity-driven filter system that removes bacteria, cysts, and sediment from up to two liters of water every minute, so you can have a full six liters ready to go in the time it takes you to set up a camp chair in the shade. If you keep the filter protector clean, the Ultra Flow glass-fiber filter can clean up to 1,500L of H2O before it needs to be replaced. The tube also comes off easily via a quick-release valve to prevent contamination, and it has an automatic shutoff to keep your fresh agua from spilling onto the ground.

    Wiping Fabric And Rinsing Filter Is Key!

    • Familiarity: I've put it through the wringer

    Knowing how to clean the fabric cover over the filter and the filter is key to keeping a good flow, especially if you are using water from a silty source.

    Remove the mesh cover from the filter. Remove the fabric that wraps around the filter. Rinse and wipe fabric with the sponge that is included. Then, rinse the filter well. You can pour water on it, swish in a container, or just swish in the lake or stream.

    Be sure you also clean the filter and bag after use, and rinse with water from the house, before and after your trip. This will get keep the water flowing.

    water filter

    • Familiarity: I've used it once or twice and have initial impressions

    a friend used this filter on a trip, so i bought one too. The filter can be a little slow, but still vastly prefer this to hand pumped filter.

    embossed numbers/letters leak

    • Familiarity: I've used it once or twice and have initial impressions

    I like that this filter is light and inexpensive. The huge capacity is great too. Unfortunately the numbers/letters that are embossed into the clear plastic of the bag all leak.

    Hey Ben,
    I'm sorry about that! That is a weird issue. I would recommend contacting Katadyn, they would have more info and can help you out!

    Best filter on the market.

    • Familiarity: I've put it through the wringer

    I spend my summers as a canoe guide. This filter made cooking, cleaning and filling bottles way less work. I hear a lot of complaints about how easy it is to gunk the filters. The trick is to find moving water (streams and/or rivers), or fill the bladder in the middle of a lake. Other than that, scrub the filter with the included sponge daily and you'll have no worries. It produces a lot more clean water without pumping or cranking for hours. It's perfect for bringing groups in the backcountry for a week, a must-buy!

    Great Gear Addition

    • Familiarity: I've used it once or twice and have initial impressions

    I have used the hand pump filter for a few years but was looking for something a little more efficient for larger groups. The Gravity Camp was the perfect option given the volume it could filter with very little work. This filter is simple to use, filters water quickly, and compact/light to pack. While I only have initial thoughts to share this product has been a great purchase so far.

    Backpacking Essential

    • Familiarity: I've used it once or twice and have initial impressions

    This gravity water filtration system is great. I recently purchased it after being frustrated with a smaller system that filtered very slow. It packs down very small and light, filters a ton of water and filters it quickly. I do wash the filter after every trip to make sure that it continues to filter as quickly, but it is so worth the time to clean! You can fill up a Cambelbak bladder in minutes when the filter is running clean.

    Katadyn Base Camp Filter

    • Familiarity: I've used it several times

    I was intrigued by the concept of a gravity fed filter after years of pumping. And had to give it a try. This product worked great the first day. Beginning the second day, the flow drastically dropped to a trickle, then to a slow drip. The sponge provided to clean the filter was ineffective. Good thing we packed a pump filter as a backup or we would have been out of water. After the trip, I tried to clean the filter at home to no avail.


    • Familiarity: I've used it several times

    I really wanted to love this and I did at first! Worked great on the first outing, where I was filtering super clear water. Got about 20-25L of water that pumped super fast and the whole group was stoked! Took it back out again this weekend and filled it up from a seemlingly clean river and it instantly clogged up and slowed down to a drip. Katadyn is sending me a replacement filter, so I will try to update. Lesson here is that this is an awesome product and awesome idea, but make sure you are filtering from ultra clean sources. Small amounts of sediment will render this useless quickly and there is no backflush option.

    Basecamp Staple

    • Familiarity: I've put it through the wringer

    I first used this 10L version on a group camping trip this past summer. We brought a back up filter but never needed to break it out because the Gravity Camp was perfect. Simply fill it up with clean water from a lake or stream, attach the hose, hang from a tree, and voile! You have the perfect base camp filter for your whole team to use. This thing filters as fast as the water can flow through the outlet tube. Filling a 1L bottle in roughly 30 seconds. As with any filter be sure to perform your due dilgence to ensure you're not filling the reservoir with silty water to prolong the life of your filter. If you perform that one simple task the filter on this thing should last you an entire summers worth of camping trips.

    This filter is a no brainer!

    • Familiarity: I've put it through the wringer

    I've used this filter bag for the past couple of years, and it's simply awesome! Have used a couple different hand pumps in the past, and have hiked with sons and friends who insist on bringing their "ultralight" silly Sawyer Squeezes. They all end up using my bag filter, because it's so dang fast and convenient. Water flow is fast enough that I've actually used it to shampoo my hair. If you're near a spring, creek, or stream you can usually fill up the bag in the water source and then hang it from a tree branch. No need to ration filtered water, because more is ready right now. It rolls up reasonably small and is reasonably light weight. I've always been careful with any filter to not use silty water (or strain it first through a handkerchief), and with proper care and post trip back flushes in the sink at home, I've experienced no decrease in the flow rate. It's basically the same white Katadyn filter cartridge as is in the Hiker Pro or Vario--it's just that gravity provides the force, not your arms. Two major big thumbs up on this product!!

    Test the filter first before trail time.

    • Familiarity: I've used it several times

    I purchased this as an adjunct to the scout troop 4l platypus filter. With a full crew of 12 an everyone carrying 3-4 liters apiece, I thought that this would really move some water. Had not tested the function before we hit the Philmont Scout Ranch backcountry. Filter did not work much more that a couple drips per minute. Tried all the usual tricks, (back flowing pulling off the matter screen) and nothing helped. So unfiltered water and water treatment pills only. Monsoon season so the streams were high and dirty.
    Contacted Katadyn when we got back and they sent 2 replacement filters ($39 ea. value) for free. Tested new filter on a recent backpacking trip and it moved water amazingly fast. Lesson learned. Test new equipment out first before you are 10,000 feet up on an alpine meadow .

    This is not a backcountry water filter

      I bought this from for a 4-day family trip through the Boundary Waters Canoe Area Wilderness, thinking it would be much easier than hand-pumping several liters of water several times a day.

      It worked great when I tested it with tap water at home, and it worked nearly as well on the first load of lake water. But by the second day the flow had slowed to a slow drip, and it took over an hour to fill a 1L Nalgene bottle. I tried all the field performance tips, but no luck. It was faster and easier to fire up the camp stove and boil water.

      I think this would be fine if you just want to filter tap water, but I wouldn’t bother if you want to filter water in the backcountry.

      This is not a backcountry water filter

        I bought this water filter for a four-day family trip through the Boundary Waters Canoe Area Wilderness, thinking it would be a lot easier than pumping several liters of water several times a day. It worked great when I tested it on tap water at home, and it worked just as well the first time I filled it up with lake water. But by the second day it was taking about an hour to fill a 1L Nalgene bottle.

        Next level

        • Familiarity: I've used it several times

        Past experience, for reference: I've spent a good amount of time filtering water in the past 10 years, using katadyn tabs, msr aquatabs, steri pen, aquamira, and an msr pump filter.

        I've used this product to filter 25-50 liters so far and haven't gotten sick.

        The ease and speed of use, and taste of the filtered water, make this product life changing for me. Steripens are a good idea but I don't like relying on batteries. I use this thing all the time and plan to use it for every adventure except for ultralight trips, in which case I'll use the msr tabs.

        Great product

        • Familiarity: I've used it several times

        I purchased this after a weekend get away with friends who had it. It was so easy to use, loved that didn't have to go down to the lake all the time to pump water and made cooking a breeze.

        Katadyn Gravity Camp Water Filter Review

        • Familiarity: I've put it through the wringer

        I love this water filter.

        After going on a weekend trip with a friend who had a clogged pump filter, I knew I wanted a gravity filter. This one delivered. I can get 6L of water ready to go in seconds, where as with a clogged pump filter, I spent a couple hours pumping enough water for our summit push the next morning.

        When you're in the backcountry, you're working hard enough already, and the last thing you want to do after setting up camp is pump water. With the Katadyn Gravity Camp filter, you dont have to.

        It weighs about the same as most pump filters on the market and is similar in size, so for me it was a no brainer.

        Any questions on this filer, hit me up!

        A camp favorite!

        • Familiarity: I've used it once or twice and have initial impressions

        We used this with a group of 5 for a 2 night backpacking trip. Water was from a low stream at both camps. We actually used a pump filter to transfer into this large 6Liter base camp filter. This allowed us to not disturb the water source creating a muddy mess. We benefited by making less trips to filter water and it was nice to have a large amount of "community water" for us to use in camp. Along the trail we had better water sources which allowed for a relaxing break as we loaded up on clean water.

        I would definitely recommend this, especially for groups of 3 or more. You may still want a pump filter in your group if it's smaller water sources.

        A camp favorite!

        Is there anyway to leave this out in the sun for a certain amount of time and use it like a solar shower? Maybe put something reflective behind it and heat it with contact?

        If you leave the reservoir bag out in the sun it will heat up over time, enough to take a lukewarm shower. You will want to get the Katadyn Shower Adaptor (Item # EXT000C) to control the flow. You could try using a reflective solar blanket to heat up the water faster.
