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.

Fantastic as always from katadyn

I’ve had these for going on 5 years and continue to purchase them for friends and family whenever we are gearing up for a big hike. My dad and I just did his first through hike through Scotland and he loved the ease and capacity of the BeFree. Just be sure to clean it out at the end of each trip and these should last you a couple of years. It is easy to just replace the filter cap when you need to.

Used backpacking, perfect

We used these on a 3 day backpacking trip and filled them from a running river numerous times. Water tasted great and never had a hint of feeling ill. I would highly recommend these as a hiking companion.

Simple yet effective.

Great for hikes. Lightweight and easy to use. I wish it used a standard bottle opening though.

Used this on a 3 week rafting trip to filter out Colorado River water. Sediment was high and who knows what was in the water. Highly recommended.

I purchased this item for use during training and running a 240mi ultra. Simple to use. Light weight and takes up little space so you can throw it in a running pack and have in case of emergency or simply as another water receptacle. Saved my bacon on a long hot run when I ran out of water and the natural sources looked sketch.

Great solution for the casual backpacker

I took this filter on a quick overnight trip and it did exactly what I hoped it would. The soft bottle helped easily filter water quickly. I used it to fill other bottles as we went. Very happy with my purchase.

One of my go-tos for many activities

I just about always have one of these in my pack. Fly fishing or trail running this is my water on the go. For backpacking I use a large gravity filter but still like to have this as a back-up for for day hikes. Highly recommended!

A must have

Must have water filter. Primarily used for self supported mountain runs. Small, lightweight and takes up no room in my pack. Part of my minimum essentials when I set out. Works as described and have never had any filtration issues.
