Fills their BeFree and leaves it upside down the night before a trip and gets perfect flow every time.

positive

Likes the 2.3 oz BeFree 1 L because it doubles as an extra vessel, giving 3 L for camp with two Smartwater bottles.

positivelight

Keeps their BeFree with its 0.6 L bag in a shoulder pocket and drinks from it without removing it.

positive

Their BeFree is fully compatible with two 750 ml Hydrapak soft flasks on their shoulder straps, letting them switch it between flasks.

positive

Stores their BeFree with water in the bottle and finds it runs faster on trail than their wife's, which she dries out.

positive

Likes their BeFree with a 2 L Hydrapak; it clogged once, which they attribute to improper storage.

mixed

Finds their BeFree pretty good with pre-filtering and maintenance, replacing the cartridge about once a year since it never survives winter storage.

mixed

A big fan of the BeFree backpacking in Arizona and Utah; with flocculation and proper care their current filter still has a great flow rate.

positive

Their BeFree works fine after a couple of years, though after a long break it needs an overnight soak.

positive

Finds the BeFree fine as long as they strain debris through a buff first.

mixed

Their original BeFree bag and a replacement Seeker both developed pinhole leaks after about 21 days and 100 L each.

mixedleaks

Prefers the BeFree for its large bag mouth, short stem and easy cleaning; they punctured the bag only once and fixed it with super glue.

positive

Their BeFree slowed after terrible water, but overnight bleach then vinegar soaks, as Katadyn advised, made it as good as new.

positive

Used a prefilter on their 1 L BeFree; the fit is tight, and they had flow issues after about a week on trail.

mixed

Their year-old BeFree, used regularly, still flows as well as on day one.

positive

Every BeFree cartridge they have had fails the blow-back test after about 30 days of solo use, but their original 1 L bag has no leaks after three or four years.

mixed

In two years with their BeFree they always pre-soak, shake-clean on the go and dry it for storage; forgetting the pre-soak once left it barely working.

positive

Still on the same BeFree in its third season; it only slowed with fine glacial debris and a shake cleared it.

positivedurable

Ditched their Sawyer for the BeFree two years ago and never looked back, accepting periodic cartridge replacement.

positive

Using the BeFree with Hydrapak soft flasks while running has been amazing with frequent water.

positive

Their BeFree bladder sprang multiple pinhole leaks and seam leaks on the JMT, so they switched to the Squeeze.

negativeleaks

Has two BeFrees, a 750 ml and a 1 L, that have lasted for a lot of water filtering.

positivedurable

On a 100-mile hike their companion's Sawyer Mini failed on day two and three of them shared their BeFree for the rest of the hike without issue.

positive

On a thru-hike, swishing and shaking their BeFree isn't restoring the original flow, but they'd rather replace cartridges than carry a Sawyer.

mixed

Finds shaking their BeFree with clear water restores flow better than swishing in a source.

positive

Takes their Katadyn BeFree on every trip without farm-runoff risk, and as a light backup to their Grayl.

positivelight

Has used the BeFree for years, but its bottle has developed pinpoint holes twice.

mixedleaks

Has had fewer issues with the BeFree in questionable water than with Sawyer or MSR, holding up in horrid ponds on the Superior Hiking Trail.

positive

Loves their BeFree with a Hydrapak bag and it has worked well, though the flip cap gets in the way.

positive

Never had any problems with their BeFree bag in a year of weekend trips.

positive

Their 600 ml BeFree bag got a pinhole they sealed with superglue and also leaks a little at the thread.

negativeleaks

On a Lost Coast thru-hike their BeFree showed no slowdown after two days while the Sawyer Mini was as slow as ever, and they love it.

positive

On a long section hike they wish they had brought their Sawyer instead of the BeFree to filter straight from Smartwater bottles.

negative

It usually takes 6-12 hours of soaking for their BeFree to run smoothly again after long-term storage.

mixed

Restored their BeFree to normal flow after dry storage by soaking it in a 5% citric acid solution.

mixed

Got stuck on trail once with their BeFree not working; now they wash it thoroughly after trips and pre-soak it for 24 hours.

mixed

Has had a few pinhole leaks in their BeFrees and patches them with Aquaseal or Tenacious Tape.

mixedleaks

Found a pinhole in their BeFree bottle; duct tape didn't work in the field but Aquaseal repaired it well.

mixedleaks

Their BeFree bottle failed, and Katadyn sent them a new one for free, no questions asked.

mixedleaks

Has had no issues with the BeFree's own bottles and finds the filter seriously great.

positive

Loves their BeFree with a 2 L Seeker and finds it much better than the Sawyer Squeeze.

positive

Has been using the BeFree with a 2 L Seeker since the start of the year; it works great and filters fairly quickly.

positive

Used the BeFree as their primary filter on a five-day solo trip and it worked fine; the backup tablets weren't needed.

positive

Has filtered 6-7 L with their BeFree for a dry camp and found it tedious but bearable.

mixed

Loves their BeFree; a pinhole a month ago was fixed with one drop of super glue.

positive

After 3+ months unused their BeFree won't flow immediately, but after sitting filled for about 20 minutes it flows like new.

positive

After their Sawyer cracked during a trip they switched to the Katadyn BeFree and never looked back.

positive

Fills their 1 L BeFree to drink on the go in the PNW, carrying a separate bottle for camp water.

positive

Just uses the BeFree's included soft flask; its wide mouth makes gathering water much quicker and it weighs only 0.83 oz.

positivelight

Their BeFree has never clogged in at least 20 trips and runs like day one.

positivedurable

Owns two BeFrees that both slowed, and dilute vinegar has restored them every time without damage.

mixed

Their BeFree bottle developed a pin-sized hole after only a handful of uses over a few months.

negativeleaks

Has both a BeFree and a Squeeze but grabs the BeFree 90% of the time, using it with a CNOC bag that scoops easily and clicks into their reservoir.

positive

Used the BeFree as their only water treatment on the South Island of the Te Araroa and it worked flawlessly.

positive

Their BeFree lasted about 600 miles, including foolishly filtering Escalante River water.

positivedurable

Uses the BeFree because they found it more robust; their Squeeze bag tore near the top.

positivedurable

Has had their BeFree about a year, using the small flask on bike rides, runs and fly fishing to scoop and drink straight from streams.

positive

Water from their BeFree still tastes terrible after running water through it many times.

negative

Has used the BeFree for years, simply drying it at the end of the season, and never had an issue.

positivedurable

Having used pens, pumps, Sawyers and Platypus setups over the years, finds it very hard to beat something like a BeFree.

positive

Has had their BeFree a few months, about 20 trail days on mountain springs, with no flow issues, swishing only every few days.

positive

Calls the BeFree the best individual water filter they have had, of many.

positive

Their dry BeFree wouldn't pass water on a day hike until it had soaked a couple of hours, after which it worked again.

mixed

Runs their BeFree in-line with Platypus and Sawyer hose adapters and finds 2-3 feet of hose really improves the flow rate.

positive

Their biggest gripe with the BeFree is its unique Hydrapak threading with no compatible caps, which is why they switched back to a Sawyer Squeeze.

negative

Loves it on backpacking and bikepacking trips, but punctured two of the 0.6 L soft flasks and moved to a thicker aftermarket 2 L bladder.

“I've used the BeFree on backpacking and bikepacking trips and absolutely love it! I did have issues puncturing the .6Liter bladder/bottle it came with”
positivedurability issues

Carries a 1 L BeFree with two Smartwater bottles and finds it more than enough for the Sierra, letting them carry less water.

positive

Accidentally froze their last BeFree and had no issues on many later outings to Algonquin and Frontenac.

positivedurable

Has been using a BeFree for over a year, still carrying 1.5 L Smartwater bottles for convenience.

positive

On their scale the 1 L BeFree system weighs less than a Squeeze plus a 1 L Smartwater bottle, and it is cheaper too.

positivelightgreat value

Loves their BeFree on weekend trips, rinsing it well with deionized water between trips.

positive

Still uses the BeFree, swapping its 0.6 L bottle for a larger Hydrapak flask; the internal filter doesn't snag and stays protected.

positive

Loves their BeFree but hates the Hydrapak bottles, which have a plasticky taste and smell they can't get rid of.

mixed

Their BeFree served them well through at least 1,000 miles.

positivedurable

Has to soak their BeFree overnight before a trip, after which it returns to its original flow.

mixed

Uses the BeFree with a 1 L HydraPak bottle clipped to their pack, usually drinking straight from the filter.

positive

Used a BeFree for a bit and it failed on them, so they went back to Sawyer.

negative

New out of the box the BeFree's flow and convenience are hard to beat; with frequent water sources they just scoop and drink.

mixed

Loves their BeFree filter and bottle: easy, convenient and it just works, with no extra parts to track.

positiveeasy setup

Soaks their BeFree in a cup of water the day before a trip and finds the flow returns pretty quickly.

positive

A long-time Sawyer user who switched to a Katadyn BeFree, which is lasting longer; they were tired of replacing filters every year.

positivedurable

Their BeFree just needs a soak: they store it with water in the bag overnight before a trip and it is good to go.

positive

Went to the BeFree after Sawyer O-rings drove them crazy and has been happy on one-week trips, cleaning it after each section.

positive

Found their Sawyer Mini painfully slow, tried the BeFree once and never looked back.

positive

On 5+ day Sierra trips with abundant water they bring a 1 L Nalgene and a 0.6 L BeFree and have never had a problem with the bag.

positive

Used a BeFree for a little over 1,800 miles of the PCT and will never go back to a Sawyer.

positivedurable

Their BeFree failed its integrity test badly before a trip even though it had tested fine a few weeks earlier, and they say this is the second or third time it has happened.

negativedurability issues

Their BeFree also failed its test; they prefer their QuickDraw overall, though the BeFree is nice for trail running.

mixed

Their BeFree failed the integrity test after fairly minimal use and careful storage.

negativedurability issues

Has had the same BeFree for four or five years and it is totally fine; they run diluted bleach through it before storing it damp and have never had a clog.

positivedurable

Their first BeFree slowed after at most about 150 L, roughly 30 days of backcountry use over four years, despite cleaning it after each trip, so they replaced it.

mixed

Prefers the BeFree over every other filter they have tried; they presoak it before trips, and their first filter lasted six to seven years with no problems.

positivedurable

Has never had a BeFree fail an integrity test while using them extensively below freezing in Montana winters, and storing them wet has stopped mid-life clogging.

positive

Has a BeFree about five years old with close to 100 L through it that still works well enough as long as they presoak it.

positive

Has both a Sawyer and a (non-AC) BeFree, and uses the BeFree solo on shorter overnights and day hikes, where they enjoy having it.

positive

Their Katadyn BeFree without charcoal always tastes fine even on some pretty rough water; it has been great and they bought a second one as a backup.

positive

Has had their BeFree since March with no slowdowns through multiple trips; mostly clear sources, but the filter has been nothing but fantastic.

positive

Backflushes their BeFree with a vinegar solution and the flow returns, but would not take it anywhere without clear water or for longer than a week.

mixed

Got maybe 60 days of heavy AT use out of their BeFree before feeling the need to replace it, by then at about regular Squeeze flow.

mixed

Switched to a BeFree after seeing how well a friend's worked on a trip; with only a half dozen trips a year the convenience wins out.

positive

An avid fan of the BeFree who has replaced it once, but its proprietary bottle thread may get them to switch eventually.

mixed

Their Katadyn BeFree has never failed, especially kept wet; they have used their first filter on perhaps a dozen trips without issue.

positivedurable

The Sawyer Squeeze was their go-to for years, but they switched to the BeFree and have been very happy with it; it is now their go-to.

positive

Loves their BeFree and has used it heavily since it came out with no problems; filter plus 1 L bottle weigh 1.9 oz.

positivelight

Has used Sawyer filters extensively and used the BeFree on one six-day trip, and was blown away by how good it is.

positive

Their BeFrees are not bulletproof, failing only when frozen, but they like the filter so much more than the Sawyer that they put up with the bags.

positive

Their BeFree with a Hydrapak Seeker has been on many two-to-four-day hikes and is still relatively free-flowing, though a bit slower than new.

positive

Their only BeFree failure has been a pinhole leak in the bladder, which happened sooner than they expected.

mixedleaks

Used a BeFree on their recent long trail thru-hike and enjoyed it more than the regular Sawyer their girlfriend carried.

positive

The BeFree is their favorite filter and they have recommended it to friends, but the Hydrapak-made bladder has twice been faulty, so they are now looking at more reliable options.

mixedleaks

The bladder on their BeFree developed a pinhole on its first trip and leaked the whole trip despite a tape patch; incredibly disappointing.

negativeleaks

Apart from slow flow until the filter wets through after dry storage, they have been super happy with their BeFree: just like drinking from a bottle, no fuss.

positive

Their BeFree stopped flowing after they ran tap water through it, but soaking it in river water fixed it; on trips they let it sit 15 minutes and it works just fine.

positive

Their BeFree failed Katadyn's blow-back integrity test after three weeks in South America, and their girlfriend's bottle sprang a leak.

negativedurability issues

Has not had an issue with their BeFree, even after months dried out; a presoak with a few drops of vinegar before a trip gets it working fine.

positive

Has used both the Sawyer Squeeze and the BeFree and says it is close, but the BeFree is the one for them; the biggest issue is life expectancy.

positive

Has had both and prefers the BeFree: much easier to use and fill with its wide neck, and quite durable despite looking flimsy.

positivedurable

Uses the BeFree as their primary filter; for them ease of use matters more than flow, and the BeFree wins out of the box: scoop water and drink.

positive

Is pretty sure both of their BeFrees started letting unfiltered water through.
