We used these on a recent RV trip. We filtered the water from the area we were in just to be safe. The bag is small enough to stick in your day pack and take with you everywhere. I also used it to filter water into my yeti. I would squeeze a bag full into my yeti and stick that in my pack for immediate use and then filled the bag again for later. Love it.As a side note we did not filter any truly dirty water so I can't speak to that. I can say the water from our RV tanks (which can harbor viruses) and other sources like that were filtered and we were fine the whole trip.Water flow was great and there was no odd taste to the water like some filters leave.

Took this on a recent backcountry camping trip and filtered water from four different lakes. I didn’t get sick so it must work. Stashes away nicely in my backpack, is lightweight and easy to clean. I’m very happy with this purchase. Would be useful in a foreign country where you can’t drink the water. No need to buy bottled water.

I have used the filter a couple of times now. Very happy, it has made the water very drinkable. I try to use clean stream (spring) water, so not too many impurities. Easy to use. Fill & squeeze.

I'm a 25-year backpacker and I've always used bleach to treat my water. I've tried nearly every other method available for water treatment and for me, bleach is just so simple and available. However, I'm getting into Fastpacking and I don't want to wait the required 30-minutes for the bleach to kill everything so after a lot research, I landed on the BeFree. I've only used it on one backpacking trip and I loved it! It's so simple, lightweight, and fast flowing that I'll likely carry it on every hike from now on. It's easy to fill in a small trickling run-off and the flow rate is fantastic. I was able to easily and quickly fill my other bottles when stocking up. I'm excited to continue using the BeFree and when water is plenty along the trail, I can carry less in my backpack because as soon as I refill, I can drink instantly. So far, I highly recommend this filter and 1L soft flask system.

It does exactly what it says. I've used it for filtering about 30L of water so far (not particularly dirty) but it's been working great. Flow rate is really fast still, and I like the collapsible bottle design - great to travel with.

I purchased this for a 3.5 day hike of the Timberline Trail in northern Oregon as a trial replacement of my Sawyer Squeeze.I tested it at home, worked amazingly well. Filtered water 5-10x faster than my Sawyer.First attempt at filtering water on the Timberline was a fail. Water trickled out. Very disappointing. But wait! I read the instructions on cleaning, conveniently printed on the bottle. I filled it again, gave it a shake, and wah chang! Back to filtering water through a jet-powered turbine!!!I like my Sawyer, but filtering water was such a long chore. The Katadyn makes filtering water very fast and almost fun. Almost.I cannot comment on long-term durability. It worked really well on my 3.5 day backpacking trip, filtering several gallons of water, some of it slightly silty from glacial melt. The collapsible, soft sided bottle made storage really easy. The downside is that it's kind of floppy if you want to keep water in it in your pack. I mainly just used it to filter into other bottles at water sources.My hiking mate was so impressed with the speed and efficiency that they immediately bought one upon return to civilization.This filter is a winner.

Ditch your Sawyer and Be Free!. The large opening makes filling a breeze and MUCH better than filling a sawyer squeeze pouch or a smart water bottle. I only needed a scoop on the very shallowest of water sources. I tested this over a couple week section hike on the AT. I had a Sawyer squeeze set up for gravity feed with a CNOC bladder (My old go-to) and this Katadyn BeFree that I was deciding on. Since I was starting at Amicalola, I knew I would be at Mountain Crossing in a few days, so I left the Sawyer at home and just brought the BeFree. I figured I could replace it at Neil's Gap if it sucked. It does not suck. I could gather from 99% of water sources without scooping, and filter directly into my smart water bottles from the BeFree. The flow rate is incredible. I would be done filtering 2 liters and cameling up on the 3rd before folks with Sawyers were done filtering their first liter.The flow rate is high enough to drink directly from the BeFree if that's your style. I have tried this previously with the Sawyer filters and found it to be a less than satisfactory process. The mini has too little flow and, even when used in-line with a bladder, the flow rate is terrible and will leave you sy=ucking hard on your bite valve to just get something to drink. The Squeeze is also difficult to drink directly from for a couple reasons: You have to squeeze the bottle hard to get water into your mouth and the bottle crushes, leaving low pressure in the bottle forcing you to break the seal to allow the pressure to rebalance.Since the BeFree is collapsible, you don't have the same problem with the difference in pressure, should you choose to drink directly from it.I hike with 2 1L water bottles. I can fill 2 of these very quickly. I also usually will chug a 3rd liter at the water source AKA "Camel up", and if I knew I was going to be dry camping that night, I would fill the BeFree 1L bladder with an extra liter, so I would have extra water for cooking and in the AM. With a sawyer, you don't really have that option unless you carry an additional bladder.Bottom line: I could not recommend this more. I was a long time sawyer user, and still have them in my spare gear box for emergencies, but the BeFree, stays in my pack.
