BeFree 0.6L Water Filter, Fast Flow, 0.1 Micron EZ Clean Membrane for Endurance Sports, Camping and Backpacking (8019639)

As a field biologist and avid outdoorsman I have used my fair share of water filters. The Katadyn BeFree has been my favorite and is my go to for most adventures. The squeeze bag is so easy and fast to use and is very durable. The filters are a breeze to change, reasonably priced, and last a decent while. I do like the 1 L over the 0.6 L bag as it's really not much heavier and you get more filtering capacity with each use.

This is an absolute game changer for backpacking. The flow rates out of this are incredible compared to my old Sawyer Mini. This filter does not adapt to as many water pouches and bottles as the Sawyer does, but it's bag folds up so much smaller and it's flow rate is so much faster that I have never found myself upset that I had to squirt the water into another bottle or pouch rather than being able to tether a clean container to the end like the Sawyer. The flow rate is such that it is nearly free flowing when drinking directly out of the filter cap.I used to dread the frigid hands, long stops, taking off my pack to pull out all of the components and endless squeezing of my old system to the point where I would end up dehydrated. This filter has changed the game. I typically filter a couple of liters in the morning that I carry as a backup in my pack and then keep the filter at hand and drop it in any water source I pass since it's so easy to drink right out of the filter and that way I'm not trying to filter a full days worth of water in the morning and carrying it throughout the day.

This is so much better than my Sawyer that requires hard squeezing and needing another bottle to filter into. You can walk by any stream and just fill up and drink directly from this, no need to set down your backpack or waste time. I had no issues or leaks on a 6 day hike.

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.

First time user after friends raved about it. I'd agree with them. It's quick and easy and stores small. I've ditched my bladder on hikes with reliable water sources. Fill this up at a stream or lake and keep hiking while I drink from it. .6L is plenty if you carry another way bottle to fill up in the event of long distances between another water source.

I LOVE this filter! I had previously been using a Sawyer Mini which works great but I was mostly keeping in my hiking pack as a backup water treatment option. The bag was hard to fill unless holding it under running water (like a waterfall), the flow was fairly low and it reauired a lot of pressure to squeeze the water from the bag through the filter.This filter addresses all the problems. The soft bladder is so easy to fill, the flow is AMAZING (one liter every 30 seconds?), and it doesn't require much squeezing. This is a total game changer. I was able to cut my carried water in half on my most recent day hike and just stopped for a quick filter and chug, drinking almost a liter in a short stop. I've heard the bag can be fragile but I had no issue with it (so far) and I plan on picking up a larger, compatible hydrapak bladder so I can filter more water on longer trips.It's also incredibly light and compares in weight to the Sawyer.Awesome product.

Love this filter. Easy to fill and fast to filter the water. Be sure to shake to “clean the membrane to keep it filtering fast.

I feel 100% confident drinking out of basically any water source with this filter. I’ve filtered from a Really small, muddy puddle and had no problems. It’s freedom to be able to go for runs and hikes and only have to be concerned with making sure there are streams or rivers or ponds somewhere along the route and not about carrying water. IN love.
