Got a great deal on the release of this filter. Nice to bring on hikes instead of packing a bunch of water.

A Wonderful Filter

Took two of these Katadyn filters on a 75 day canoe trip with 3 other group mates. We would filter water throughout the day in our canoes as we paddled and we were in no shortage of fresh clean water to drink. Even on the silty waters of Lake Winnipeg, the filters continued to work (with occasional rinsing). Would recommend letting the water filter into a "clean water" bag, instead of straight into your water bottle, as it does slow down the more you use it.

Great Filter

Works as intended Very easy to clean Simple to use Only thing I wish it had was a way to stop water flow without the tubing. Maybe there is a cap from Katadyn? The ability to use it without a filter would be nice, too.

My Standby

Been using Katadyn BeFrees for years, pack the 3.0 liter away for camp, use smaller one during the day. Thicker material is better, as I regularly got pinhole leaks from impatiently squeezing to move water through recalcitrant filters. Wish they could do something about that, since the detach and swish "fix" doesn't really do the job. Pro Tip: bring an extra filter in case you lose one or it gets hopelessly clogged.

Works Great…

This size was on flash sale so the price was enticing enough to give it a try. For backpacking - which is what I purchased this one for - I’d probably get one a little smaller. On the plus side since it holds a lot I can fill it at the water source, bring it back to camp, hang it and use it for quite awhile. It works pretty well as a gravity filter, too. Closing the cap while it’s hanging squirts water on you - be careful! Opening is pretty small so having a cup to fill t at the source is helpful. Super easy to use…

Basically like a platypus gravity filter but BeFree. I like the ease and convenience of this set up. it makes filtering lots of water a quick process.

Easy to use. Size is great for 2 people camping together- you can get 2 cups of coffee and breakfast all from one bag which is a big convenience. Easy to clean and holding up well a year later!

It Works

Great for campsites where you can let gravity take its time to work

I use this on every camping trip! It's so easy to use and packs really small. I love being able to hang and drain, which doesn't take long at all. It's generally fast enough that I can just hold it up long enough.

It Wouldn't Work At One Point...

I really wanted to give this more stars, but since I had issues with it on my last backpacking trip, I couldn't. I was in the Grand Canyon, and it just would not GO...at all. Not sure what I was doing wrong. So, I packed it all back up and decided to figure it out later at my campsite. It suddenly started working. I'll need to look up some trouble-shooting tips. Pros: It's light and can filter 3 L of water at a time. Cons: Sometimes doesn't work. Filtering is very slow. UPDATE: I still have issues with this filter. I found that if I soak it in distilled water after every trip, it helps some. The first filtering is always the most frustrating.

Love It - Works Easily - Great Size For 3-4 People

Used it backpacking in CO last summer. really convenient. Nice to drop weight by no longer carrying a pump.

Ideal Lightweight Clear Water Processer

I'm quite attached to my multi-branded frankenstein of a gravity filter, with its 5L roll-top resevoir, inline filter, custom hose length and water bladder quick connector. Jealousy struck me, however, when a friend whipped out this setup. It's about as bare bones as you can get and still process and/or transport a solid volume. I like the handle for hanging to drip into a bottle. It's easy to drink out of too. Like other similar gravity filters it plugs easily with silty or very dirty water. The bladder is prone to pinhole leaks and leakage around the seals. It is choice for saving weight and treating clear water when boiling or chemical treatment isn't ideal. I would like a way to connect it to a bottle or reservoir, maybe with a hose, but admit that I might be missing the point.

I have used the Microfilter on multiple backpacking trips this summer (2024) and it has proven to be much more convenient than my old pump style filter system. It is lighter, faster, and less effort. Highly recommend.

Great For Car Camping With The Family

My wife and I do a lot of backpacking - never in our life would we need something as big as this. Now with the introduction of our daughter who is now 1.5 years old, this made primitive camping so much easier without worry about having to hump in gallons of water. Tastes great, filters fast, and easy to clean - 10/10 would recommend!

Good Water Reservoir For Temps Above 40

Worked great at Pinon Canyon as an easy access water refill vessel for my crew inside the Stryker. Struggled with water flow at 11000ft with temps bouncing between 50º and 38º. Once we camped next to a creek it was easier to fill a Nalgene and steri-pen all the water. I'm keeping it in case of brackish water in the future. Pro: didn't get sick at all Con: slow refill Space filler Space filler
