    Think of the possibilities.

    Do you ever wish that you could drink from crystal clear creeks, alpine lakes, or mountain streams? Well, you can when you bring the Katadyn BeFree Water Filtration System on your next adventure. This compact water bottle with integrated filter makes a great choice for outdoor pursuits and travels to faraway places where tap water is suspect.

    Instead of lugging around a bulky pack loaded with a full day's worth of water, just bring this lightweight and compact bottle along with you. Simply fill up the flask and let the EZ-Clean Membrane do all the work. It's effective against microorganisms and even suitable for cloudy water. And when it's not filled, the collapsible bottle packs up small so you can stash it in tight spaces.

    • A portable water filtration system for hiking and travel
    • EZ-Clean membrane filters out microorganisms and debris
    • Collapsible bottle packs up small for easy storage
    • Clean filter regularly to extend life of filter
    • Item #EXT000G

    Katadyn Be free Water Filtration System

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

    So portable and packable. Fits well in my backpack!!! I have the 1L. As long as you have a water source you are gtg!! Love this system!!!!


    • Familiarity: I've used it several times

    This filter is amazing!! So light weight and packs small. Awesome for overnight Backpacking trips. Not having to carry 4L of water (Depending on water sources of course) is a MAJOR difference. I have felt that not having to carry as much water opens up a lot more possibilities in the backcountry.

    Almost all positives

    • Familiarity: I've used it several times

    Other filters tend to have relatively slow flow rates, but this filter has an adequate flow rate for me and probably you. The one issue I have with this filter is that even though the bag is plenty strong and usable, it’s difficult to get all of the water out because of the firm plastic rim around the mouth, don’t get me wrong, works more than well enough, but im subtracting one star for that reason.

    game changer

      I love this system. I am usually always near a water source, so I no longer need to carry around a heavy load of water. I just drink when I'm thirsty. Last summer We used one filter for three people on a 10 day river trip. It's a very reliable and lightweight filter

      game changer

      Fantastic Fishing Filter

      • Familiarity: I've put it through the wringer

      This filter makes a fantastic addition to your fishing vest. Not having to carry a large water bottle when hiking to get away from the crowd, but having plenty of access to water makes this bottle my must have on the river. It has worked phenomenally well over time and filter hasn't clogged yet, although I have sought clean water to filter.

      Really good flow!

      • Familiarity: I've used it several times

      I brought this filter on a handful of High Uinta backpacking trips and the flow is really really good. The flow is 5x better than the Sawyer Squeeze. The only thing i would be careful for is the bladder itself as it's not the most durable thing, but still gets the job done. Just don't squeeze the bag too hard!


      • Familiarity: I've put it through the wringer

      I recently replaced my MSR trailshot filter with the befree as it is lighter, faster, and cheaper. I have been using it for trail running, just throwing it in my vest and using it to fill up my hydration bladder (I can fill the 1.5 L bladder in about 90 seconds even with the .6 L filer). I am unsure how long the filter on this will last, but for a 2oz filter that easily fits in my pocket I really cant complain. I recently used this for a self supported 38 mile run and never had to stop for more than 3 minutes to fill up and never felt like I had to use extra effort, unlike other pump type filters or heavier alternatives. This is definitely a major step in the right direction of on demand water filtration!

      The Bees Knees!

      • Familiarity: I've put it through the wringer

      Just returned from a Colorado Trail thru hike and this little beauty is super easy to use and super fast! Collapsible bladder allows for minimal weight and storage footprint, while filtering water as fast as one can squeeze.

      So far so good!

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

      I love this, so far! Light, and eternally useful. I will be careful about how mucky of water I use, since I know the filters will clog up faster. But, outside of that, I have faith this will last a good while. Especially for this price!

      So far so good!


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

      ...resource in the backcountry! Best 1L filtration device on the market. I like almost everything about this device, however I am a touch bit concerned with the cap design, particularly the hinge that gets a ton of use, ON/OFF...concerned that it may be a little flimsy and eventually break?

      I feel the same way ... haven’t broke one yet but it can be a tight fit to snap closed ... I carry a life water or smart water
      Sport caps with me so if it dose break the caps from both of those brands fit the top
      Of the one Ltr be free

      Very easy to use!

      • Familiarity: I've put it through the wringer

      After repeatedly having to replace my Sawyer Squeeze Filter because they kept breaking, I bought the BeFree. It’s really great! I used it on several trips this summer. One thing I really like I about it is the hard shell around the mouth—this really makes it much easier to fill since it is a soft bottle. It also seems to be very durable—it has lasted longer than any of my previous filters!

      Works great, until it doesn't

      • Familiarity: I've put it through the wringer

      Initially I was very impressed with this filter. I have used just about every kind of water purification extensively, and I really like how small and light this filter is. Initially it was very fast, much faster than the Sawyer squeeze filter. The bag is a softer material but actually seems tougher than Sawyer's. However, after less than a year of use, exclusively filtering in clean mountain streams and lakes, the filter rapidly slowed and is now impossible to use. I have purged it as instructed regularly in the field and always rinsed well and dried before storage. When I contacted Katadyn, they told me this is meant to be a disposable tool and will just slow over time. Next time I will buy another Sawyer, as they have a lifetime warranty.

      Another Chance

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

      Filter clogged on the first day of the very first trip (5 days). Used only in relatively clean (by appearance) and flowing water. I cleaned over and over, as suggested, with no luck. I was really excited after I received it during home tests. Water flow was initially great...really fast with big volume. When it clogged it did not just slow down, it all but stopped. Thankfully I had brought tablets. I'm ordering a replacement filter with fingers crossed that I just got a defect. We will see!

      Very easy and works well

      • Familiarity: I've used it several times

      I've used mine for two backpacking trips so far for quick drinks out of the river. Product works great and it doesn't leak. I plan to buy another one.

      Katadyn BeFree Water Filtration System

      • Familiarity: I gave it as a gift but have feedback to share

      I sent this to my brother in Florida in preparation for Hurricane Irma. Hopefully he won't have to rely on it.

      Faster than a Sawyer

      • Familiarity: I've used it several times

      Impressed so far. I've only used it a few times, but it is really fast and I love its compatibility with the Hydrapak Seeker. Only drawback is that flow rate can be quickly diminished requiring a quick back-flush. As someone who hates all water filters--I'm a happy camper with this one.

      Drink without squeezing

        I haven't tried other person filters like this before mostly because I've heard negative things like you have to squeeze or suck really hard to force the water through the filter. I would rather just stick with a larger filtering system and fill up my Camelback. That is not the case with the BeFree filter! Scoop up some clear water from a nearby stream, river, or lake, screw the top on, and tip upside down and a nice steady stream of clean water will come out! You can squeeze the bottle to make water come out faster if you want but is not needed.
