Great Water Filter

Love this, a major upgrade. I have used this on several backpacking trips and it works great. I also love it for big bike rides when I don't want to carry a ton of water I can easily refill my bottles in the streams along the way.

Works great. Easy to use and packs down very small when not in use. Highly recommend it.

Best Water Filter On The Market

I have tried them all, and this one is hands down the best on the market. Used this on many expeditions. Great water flow. easy to clean.

Great Choice For Through Hiking

I hiked the Appalachian Trail and used the Be Free the entire time. I was very impressed with the rate of flow and how easy it was to clean. Its always my go to filter for hiking and always with me.

Flow Rate!!!!!

This is the perfect lightweight water filter. I don’t drink out of it - I use it to fill other bottles. The non rigid bottle allows you to squeeze water through the filter and it’s incredibly easy. You can squirt the entire bottle out through the filter in about 5 seconds. Highly recommend for someone looking for consistent filtration and packability

So Useful!

Love this for backpacking in the mountains! It's a great grab-and-go option that allows me to have a portable water bottle for camp and day hikes from the back country. The only thing I don't love is that the description says it's blue, but it's actually more grey.

Fast

Fast to grab but not my only solution when water is very shallow

Worked Great!

I got this filter before I did a multi day back country elk hunt this last fall. I loved the light weight compact size of it, and it filtered great and worked as intended when I had to do daily water runs to filter water for drinking. 10/10 worked as advertised and I didn't get sick. If you need a way to filter water I can't see any reason not to run this, it's a little small but it made quick work of filling my 7 liters of water storage.

Plenty In Patagonia

I have used the Katadyn BeFree in Alaska, the Boundary Waters in MN, and in Patagonia. It has been a consistent and reliable water filtration in the most remote areas. In Patagonia, my BeFree filtered water for three people, for 7 days and over 70 miles. As a newer backpacker worried about safe water, BeFree was easy to use. It filled easily in the rivers and streams and is lightweight and easy to pack. I would be careful about where and how you pack it to make sure you don't puncture it on rocks or anything sharp in your pack. To me, this is an essential piece of my backpacking kit.

Form Meets Function

[This review was collected as part of a promotion.] Simplicity: 10/10… fill the water bag, close the lid and drink! You can carry it in your pocket or attached to your belt loop or backpack with a carrabener. Durability: 8/10 … excellent quality. The nature of what it is, there is some minor risk of puncturing the bag and losing the secondary charcoal filter. Packability: 10/10: maybe my favorite feature. No carrying extra weight or bulk with this. Packs down to nothing and shrinks as you drink the water. Flow rate: 8/10 … quick. As expected for the fiber style filter. A little slower with the secondary filter installed. Ease of cleaning: 10/10: so easy to just swish around the filter in the creak to clean debris. I am curious how effective this method is over time. Katadyn Group gave me this free product to try.

Solid Product

Only drawback is the slow flow rate, otherwise a great product. Primarily used to drink chemically filtered water and adjust flavor.

Best Filter I’ve Ever Used

Most convenient filter I’ve used. I’ve taken it on long runs in the mountains and filled up in springs along the way, the flow rate is very fast and easy to get water out of. I always carry one in my hunting pack and fill up when I find a water source . It’s super lightweight so you can squish it and keep the empty bottle in a pocket or pack.

Highly Recommend

I took this on a multi-day trek in 2026 in South America & was so pleased with its performance. I will continue to use my 4L-6L reservoir-style gravity filters when camping/backpacking with larger groups, but otherwise this is the only filter i'll ever use again (aka-throw away those other 'squeeze' filters from the other brand). So happy with this product!

Filter On The Go

Easy to refresh the filter and worked well in remote areas with questionable water purity. Highly recommend for an ultra portable filter.

Compact And Simple To Use

I carry these on any long run/hike where I might run out of water. Makes filtering stream water very easy.
