Montana mountains last season had plenty of flowing water that we had to boil because reasons. A spare bottle in kit would have been so great to have, but poor planning taught a lesson Id ought not to learn again. So learn from me and have a backup means of purifying water. Or a backup to your backup, why not? Either way, no one ever complains about having extra necessities, or resources to better gather them.

I’ve utilized this filtration system for everyday travel and the need for great drinking water.

This filter bottle works great for its intended use i.e. quickly providing filtered drinking water for one person on the go. I used it on a self support kayak trip on the Middle Fork Salmon and backpacking on Mt. Rainier and it worked great to keep me hydrated during the day. Admittedly I had access to very clear water with little sediment so the filter didn't clog up. Using it on a desert river or hiking trip might not work as well.

Dip and sip, it works. Used this for backcountry hikes in the Sierras, where admittedly I have opted to not filter and never had an issue. This bottle is so easy to use no reason to not filter. Bottle is flexible enough to squeeze into a larger bottle if needed.

Worked well on a backpack trip .. was a little heavy

Love the ease of filtration with this bottle, as opposed to the soft squeeze. Although the bottle is a little smaller than a traditional bike water bottle, it wants to jump out of the cage more than a traditional bike bottle would.

I bought this when camping on a lake and it was amazing. I used it in combination with the Steripen Classic 3 UV Water Purifier and it gave me peace of mind as well as delicious tasting water! I didn't taste any sediment or weird flavors at all, and I didn't even use the carbon filter. Also very light to carry around! Highly recommend!!

I’ve taken this bottle just about everywhere. It is simple and easy to use. Compared to other water filter products that were more of a pouch style this is still lightweight but much more durable and not prone to the same pinhole punctures. The flow rate is pretty quick too. I used this on hikes, bike rides, and in my day-day where water quality was questionable. A filter product is essential for me as someone who spends a lot of time in the backcountry as a guide and adventurer and this will definitely be my go-to this year. I would highly recommend this to anyone looking for a simple filtration solution whether traveling or in the backcountry. I’m excited to try it this summer while guiding on the Middle Fork of the Salmon River. I received this product for free in exchange for my honest review.

I received this product for free in exchange for my honest review. This bottle is amazing! I used this bottle on a road trip and never had to worry about contaminants in my water. The system is extremely easy to use and very easy to setup. The instructions are very clear on how to set the system up. The instructions manual is very detailed about the care of the system as well as cleaning. The system is pretty durable, and I really like how flexible it is. It can basically fit anywhere. I thought the flow rate was particularly good considering how beefy the filtration system is. I did not feel like I had to work hard to get a sip of water like you do with some systems. This system is also so easy to clean and like I mentioned previously, the instructions are very detailed on how to go about the cleaning process. Katadyn Group gave me this free product to try.

I am a long time user of the BeFree filter and have dozens of backpacking trips with it. I use mine with the BeFree 3 liter bag. I was excited to have the opportunity to try out my beloved filter in a new bottle set up. BeFree did send me this bottle filter to review for free but the opinions are my own and not influenced by its freeness. Out of the box, I felt the instantly familiarity and confidence in the filter due to my past experiences. The filter element looks the same, it’s just now part of the bottle lid with a flip top cap. The cap and the flip top felt robust and not flimsy or cheap. The bottle part has a good amount of rigidity but has plenty of flex to squeeze it without being a workout. Sturdy but flexible at the same time. It has a small Carbon cylinder that you can add to the lid just under the opening to help with taste in the water. It does slow down the flow noticeably but it was still very acceptable flow. The bottle could not be easier to use. Just fill it up, screw on the lid and drink. Filtering out bacteria, microplastics and other contaminants in the water. I would recommend this to be used in any application where you can get water from sources as you go through the day. I used it for biking and it fit into a frame mounted water bottle holder. I used it during kayaking and strapped it to the deck of the kayak. I will mostly use it for hiking and backpacking as any easy and quick way to get my water. Well done BeFree. Thank you for the filter. See you on outside. Happy Trails.

I think it is great. the only thing I was left wishing for was that the filter was able to fit on different sports bottles and the air release has a little bit of a noise it makes. It tends to squeak a lot!

I received this product for free in exchange for my honest review. At first I was a little skeptical of the product. I’ve used the befree filter and bag for so long. But honestly this has been a great new addition to my hiking gear! Recently i’ve switched over to just using a water bottle for hiking instead of a bladder, and this fits that need. Instead of needing to carry two separate containers, i can just use this. The bottle is perfect too because if i do need to filter water into another container, i can! The flow rate and cleaning were super easy, just like with all the other befree products. I’m also super excited to use this while traveling in countries where the water is not safe to drink. This product will be perfect to provide some peace of mind. Definitely recommend!!

This system is super easy to use. The directions are clear and concise. The system was super durable. I have had no problems. I used it three times all in very cold temperatures, but the flow was still incredible. The system is very easy to clean, which makes it perfect for travel on backpacking. Katadyn Group gave me this free product to try.

I recently took the Katadyn BeFree AC 0.7L filter bottle on a 2 day backpacking trip, and it worked like a charm. The stream water tasted great and I had no stomach issues. I enjoy the translucent dark color of the bottle. The plastic is thin but feels sturdy enough to take a decent tumble. No more punctures! It flows faster than my old sawyer filter too! This filter is light weight and the perfect size for backpacking. I recommend this filter to anyone who prefers the 2 in 1 design vs gravity/pump filters. I received this product for free in exchange for my honest review.

I’ve used the 0.7L Katadyn BeFree, and it’s honestly one of the easiest water filters out there. It’s super lightweight, fits in a running vest or backpack pocket, and you can drink straight from it like a normal bottle. The flow rate is fast, and cleaning it is as simple as swishing it in water. If you want something simple, reliable, and perfect for hiking, travel, or emergency kits, the BeFree is a great choice.
