Why We Like The Gravity BeFree 6L Microfilter
The Gravity BeFree 6L Microfilter is simple and easy to use. We fill it up in our nearest stream, hang it on the closest tree or the back of our car, and let gravity do the work. It cleans water fast with its proprietary flow technology, letting us get back to doing what we want to sooner.

My go to filtering solution
This water filter is amazing. Once you get the couple tricks on it (hydro locking, filling), it filters quick, fast and reliably. Hydro locking: sometimes you'll get air bubbles that will slow the filtering. one trick we've learned is to presoak the filter element, because it doesn't filter well the first round otherwise. Also, having a small pot or bag to fill and then dump into the filter can help, but the best is filling it in a flowing stream.

Super fast and easy
This is my favorite piece of backcountry equipment. I wish I could give it more than 5/5.

Reliable and Fast for Group Backcountry Trips
I recently used the Katadyn Gravity BeFree 6L Microfilter on a backcountry camping trip with 10 people, and it exceeded expectations. We were camped right on the lake in 80-degree weather, going through a lot of water, and this system was a champ. I kept it hung on a tree and refilled it using a couple of 1L Nalgenes to keep the filter clean, which worked perfectly. The flow rate was fast, making it easy to keep everyone hydrated without turning water collection into a chore. Compared to the smaller filters I normally use for solo or small group trips, this was a game changer for larger groups lightweight, easy to use, and highly reliable.

Great for groups
Worked great, maybe an included stand would be useful. Used to collect water from a lake, hung on tree for camp members to fill up and use for food prep.

So light! So easy!
I just got back from a 4 day back country mountain summit. I used this filter because I knew I had some big water carries and didn’t want to hand pump them. This was my first time using this filter and I loved it. Fast flow, easy to fill. Just perfect.

Great for base campsite cooking station.
It has been a good product. We have used it at camp while taking day hikes from our campsite. No issues, and I have used Katadyn filters for 30 years. They are worth the money. Ingesting a parasite could be a lifetime health issue and ruin a trip. Water is too heavy to carry.
