A bacteria-filled seaside. A muddy wetland. Glacial silt runoff. The perfect backpacking water filters have to have the ability to deal with some fairly gnarly water sources with out clogging or breaking. I examined the 20 backpacking water filters on this story by taking them to 3 totally different water places, pumping three liters of water by every filter. After every spherical, I timed how lengthy it took every filter to deal with a liter of faucet water earlier than persevering with to the following spherical. On the finish of all three rounds, I weighed every filter.
Further enter on ease of use and sturdiness have been offered by members of the Outside Life backpacking gear testing crew over three days of climbing by the Goat Rocks Wilderness of Washington State.

For a very long time, it was laborious to decide on a winner between the Sawyer Squeeze, the Platypus QuickDraw, and the Katadyn BeFree. Every managed to barely one up the opposite in key classes, like weight, worth, and move charge below quite a lot of circumstances. But it surely wasn’t sufficient of a distinction to place a filter excessive.
Sawyer modified all that by partnering with backpackers’ favourite water bottle model: Cnoc. Proper now you may select between a two liter bladder and their classic Vesica bottle (primarily a collapsible Smartwater bottle for the uninitiated). I examined each, and personally choose the bladder for its ease of use. Not solely was it simple to fill and simple to squeeze, I might even hold the bottle up on a low department due to the loop within the plastic closure, creating an impromptu gravity filter — which actually labored higher than a number of the precise gravity filters I examined. However most backpackers will possible choose the familiarity of the bottle, which you’ll connect the filter to and simply drink straight out of. Simply notice that it’s noticeably extra annoying to make use of the Cnoc bottle to filter a number of liters of water at a time.
The remainder of the Sawyer filter stays as wonderful as ever. It carried out nicely in my testing below quite a lot of circumstances, from murky swamp water to silt-filled rivers. It’s simple, and fairly efficient, to backflush, rapidly restoring move. And it stays one of many extra inexpensive choices I’ve examined. If you have already got a bottle system you want, or simply want to interchange the filter component, Sawyer additionally sells a filter with none accompanying bag.

There’s a lot to love concerning the Katadyn BeFree AC. It’s been a standout performer throughout testing, dealing with each water supply I’ve thrown at it at a degree that can fulfill even the thru-hiking set. The Katadyn BeFree can be very light-weight, and requires no instruments to scrub its filter past a bit of unpolluted water. The AC model of this filter can be noticeable in that you may add a carbon component to it that can enhance the style — fairly useful if you end up consuming out of a cow trough one too many occasions.
Whereas earlier iterations of this filter had a too-flimsy bottle cap (you may simply snap it off), this one errs too far within the different route. It’s very sturdy, however sadly, very tough to make use of. I nearly couldn’t flip it up simply utilizing my arms, and ended up resorting to leveraging it towards a desk, like I used to be opening a beer bottle. (My husband was in a position to open it with solely reasonable effort, so that is clearly a hand energy challenge on my half.)
I’ve additionally had blended success with the “swishing” methodology for cleansing this filter previously. Generally it really works nice to revive move; different occasions it makes move worse. Count on to interchange this another typically in comparison with the likes of a Sawyer Squeeze or Platypus QuickDraw. But when the place you might be headed to has questionable water choices, the choice to simply enhance style could also be value it.

Whereas the Platypus QuickDraw was a hair behind the Katadyn BeFree (with out the carbon filter) after the preliminary spherical of testing, it was out in entrance of the pack on the finish of testing. The one spherical the place the QuickDraw struggled was within the mucky water of the wetland, though I didn’t backflush it till after the glacial runoff spherical as its move was nonetheless forward of nearly all of filters. As soon as backflushed, its efficiency was restored to shut to the extent that it had out of the field.
In contrast to the Sawyer Squeeze, you may backflush the Platypus QuickDraw with a Smartwater bottle. Whereas I appreciated that I didn’t want a separate software to backflush the Platypus QuickDraw (one thing I’m susceptible to dropping), I did discover that the cap to the filter prevented me from making a flush seal with the clear aspect of the filter.
Nonetheless, the smooth pliable materials of platypus soiled sack mixed with the positioning of the filter component on the inside (moderately than on the within of the bag), made this the second most nice filter to squeeze water out of in my check (after the Sawyer Squeeze paired with the Cnoc bladder).

The mini-me model of the Sawyer Squeeze is the right filter for ultralight fanatics — sufficiently small that it received’t take up a lot actual property in your backpacking backpack and lightweight sufficient (even after the ultimate weigh-in) that you may scrub an oz. or extra off your spreadsheet. Even higher, it’s so inexpensive that it wouldn’t damage your funds a lot to simply substitute it every season. The place it wobbles, unsurprisingly, is in performance. It takes about twice so long as the usual Sawyer Squeeze to filter a liter of water. After all, in case you plan to connect the filter on to a SmartWater bottle and suck the water out from there, that may not matter a lot to you.
I used the offered soiled bag throughout testing and was impressed with its sturdiness. Even after squeezing the bag as laborious as I might to push the water out over ten rounds of filling and filtering to succeed in the specified 5 liters, the bag nonetheless regarded like new. I solely want that it was bigger—the bag that comes with the mini is 16 ounces moderately than the usual liter. One thing else I seen throughout testing was that the filter itself didn’t seem to screw onto the bag accurately. Every time I attempted to repair it, the angle would nonetheless be lopsided. Thankfully, there have been no leaks throughout testing so this seems to be primarily an aesthetic concern.
Whereas the move charge for the Sawyer Mini was not particularly spectacular (about 4 occasions so long as the Katadyn BeFree), I did admire that it got here with a light-weight syringe to backflush the filter when it begins to clog an excessive amount of.

I’ve examined each the Grayl GeoPress (in titanium) and the UltraPress (in plastic). Each these filters use the identical filter know-how, so you may count on comparable efficiency below difficult circumstances. Each are supplied in both plastic (polypropylene) or titanium. The latter of which may be very costly.
However let’s first have a look at how the Grayl works. It’s a bit like a French press. You pull out the inside tube, fill the bottle up with water to the specified line, after which push the inside tube again down on high of the water till it’s all pushed by the filter on the underside. This works finest in case you put the water bottle on the bottom and permit your physique weight to do the work of pushing the water by.
Whereas Grayl boasts a really quick move charge for this bottle, the precise charge may be very a lot affected by how a lot effort you place into it. Most individuals can count on a half liter to take about 30 seconds, whereas expending reasonable effort. The filter itself can be distinctive, because it makes use of carbon to draw viruses utilizing electroabsorption (which is a essentially totally different course of than filtering them out, such because the MSR Guardian does).
For backpackers, there are a handful of points that add as much as this being not fairly the correct alternative. First off, it’s fairly heavy, even when considering the advantage of having a built-in water bottle. Within the backcountry, this added weight goes up much more, because the final half inch or so of water within the Grayl doesn’t filter by the inside tube, and is solely left sitting on the backside of the bottle after filtering. The filter itself additionally has a a lot shorter lifespan than different backpacking filters, with Grayl promoting that you may count on about 350 liters out of it.
Throughout testing, the filter was very affected by our gnarliest testing website, the glacial runoff, suggesting that in much less pristine elements of the backcountry this filter could final considerably much less time than 350 liters. And when this filter begins to wrestle, it turns into an actual nightmare to try to use. A minimum of with the squeeze baggage you may sit down whilst you wrestle away (and perhaps even backflush!), with the Grayl you’re caught standing up, throwing your entire physique weight down on high of a tiny lid that’s only some inches in diameter.
However what concerning the virus filtering? Effectively, only a few backcountry water sources are contaminated by issues like rotavirus, as a result of these are sometimes human-borne pathogens. Backpackers don’t want this type of firepower. Right here’s who does: anybody dwelling in or visiting elements of the world the place the water popping out of the faucet isn’t reliable. That water might be working clear, too, so the lifespan of the filter shall be that for much longer. In the event you’re on the lookout for a journey water bottle that can defend you from nearly all the things, from e.Coli to giardia to cryptosporidum, that is the filter for you.
I’m a sucker for titanium as a lot as the following backpacker, so I used to be excited to take a look at the titanium model of the GeoPress in my second spherical of testing to check to the polypropylene Ultrapress I had examined beforehand. After testing, I’ll be sticking with the polypropylene model. Whereas the aesthetics of the titanium bottle are undeniably cooler than the plastic one, this doesn’t overcome the performance challenges (or the worth). The most important challenge right here is usability. Whereas it takes just a little elbow grease to tug the inside tube with the related filter out of the principle housing on the polypropylene model, I struggled to get the inside tube out of the titanium model in any respect. And this doesn’t include the everyday titanium profit — this model is heavier than the plastic model.

The Sawyer Micro is correct in between the Squeeze and the Mini. It doesn’t have the knockout efficiency of the Squeeze, nevertheless it weighs much less. It had a greater move charge throughout my testing circumstances than the Mini nevertheless it weighed extra. For some backpackers, that will put it in a no-man’s land; for others, it could possibly be the right Goldilocks product.
One different benefit of the Sawyer Micro is that, just like the Squeeze, you may pair it with one in all Cnoc’s bladders. I notably like how minimalist and utilitarian the Cnoc 750ml liter pouch it was paired with was. It’s very mild (weighing solely 3.1 ounces) and comparable in operate to the Sawyer soiled water pouches of yore.

The MSR TrailShot is barely heavier, barely pricer, and never fairly pretty much as good as a performer as one of the best squeeze again backpacking filters, however its distinctive design makes it an fascinating present for particular functions. With the squeeze bag filters, step one is to replenish the bag — generally simpler stated than executed in case you’re taking a look at a desert seep. However the TrailShot has an consumption that’s nearer to a conventional pump filter, however shrunk down such that it might slot in nearly any water supply worthy of the identify. That’s a sport changer in case you don’t have the curiosity or endurance to take a seat round Macguyvering an answer to a tough to entry water supply.
In testing, I discovered the hand squeeze mechanism of the TrailShot to be pretty tiring. By the top of the third spherical of testing, it was one of many filters I dreaded utilizing. And whereas its efficiency was enough for murky water sources (if not distinctive), it struggled with the glacial runoff, taking up 4 minutes to squeeze out a single liter.
In the event you’re a hardcore path runner, or simply an exceptionally impatient particular person with distinctive hand energy, this filter could be the reply to your wants. However the overwhelming majority of individuals shall be higher served by one of many high-performing squeeze bag filters on this record.

LifeStraw is likely one of the most well-known manufacturers in water filtration, due to the ubiquity of their LifeStraw filter, which they distribute to highschool kids in rural Kenya. Their Peak Collection filter is a barely costlier, barely higher performing backpacking water filter in comparison with the unique LifeStraw. They supply their Peak Collection filters as a part of a squeeze bag filtration setup; sadly, in testing it didn’t carry out on the degree of extra in style fashions just like the Katadyn BeFree, Sawyer Squeeze, or Platypus QuickDraw.
One benefit of the LifeStraw Peak Collection is that you’ve the choice so as to add on a carbon filter for an additional price that may assist enhance style. In case you are touring in areas the place you’ll be sharing a variety of water sources with cows, or pulling water out of stagnant ponds, then this can assist make your journey extra nice. Nonetheless, there have been points whereas I used to be testing the carbon filter choice for the LifeStraw Peak Collection. The primary is that the carbon component, which is about the identical size of the common filter, screws onto the top of the prevailing filter. Because of this the filter component contained in the squeeze bag is sort of so long as the squeeze bag itself. It’s not terribly simple to squeeze all of the water out of it with this setup, as you may’t roll down the bag as you go. The opposite challenge is that whereas testing this filter arrange, the bag for the LifeStraw Peak Collection ended up with a small gap in it, forcing me to finish testing of this component sooner than I had hoped. In case you are taken with including a carbon filter to your backpacking water filter to enhance style, go along with the Katadyn BeFree AC. In the event you’re taken with eradicating heavy metals and different difficult contaminants, go along with the Grayl GeoPress.

The RapidPure Air purifier+ was one of many worst performing filters in my check, taking up two minutes to filter a liter of water out of the field, and over 5 minutes after I examined it out at a murky swamp. Whereas it was considerably distinctive amongst squeeze bag filters for utilizing activated carbon to assist filter out viruses (the Grayl filters additionally do that), my sense is that the efficiency right here is poor sufficient that you’d be higher off snagging some chemical therapy — like Aquamira – moderately than coping with this simply clogged squeeze bag filter.

At its core, all a water filtration system must do is transfer soiled water by a filter, with out inadvertently contaminating the clear water vessel on the opposite aspect. One of the crucial in style types of backpacking water filters leans into this simplicity: all a person has to do is replenish a plastic bag with soiled water, connect the filter, after which squeeze the water by into their consuming vessel.
The thought behind a gravity filter is pretty simple, as a substitute of compressing or pumping soiled water into your consuming vessel, let gravity do the give you the results you want. After filling up the soiled bag—which holds as much as three liters within the case of Katadyn—you then elevate it by putting it on a big rock, hanging it in a tree, and even holding it your self, no matter works. The upper the water is, the quicker it should move by the filter, however it should work so long as the bag itself is increased up than the top of the outlet hose. Then you may simply stroll away whereas gravity forces the water from the soiled water sources into your clear container.
All of the gravity filters in my check got here with a flask of at the very least three liters, which is good in case you are touring with a number of folks, because it reduces the variety of rounds of filling up your soiled flask that it’s worthwhile to do. The Platypus GravityWorks takes this a step additional, with a grimy flask capability of 4 liters. Even higher, it comes with a second bladder to filter your clear water straight into it.
In testing, the GravityWorks took about twice as lengthy to filter a liter of water after the primary stage of testing because the Katadyn BeFree; nevertheless, it was practically unable to course of the glacial runoff, taking an hour to filter a liter of water after the third stage of testing. After utilizing about six liters of water to backflush the GravityWorks, which is achieved by merely elevating the clear water reservoir above the soiled reservoir and permitting the water to move backward, the move improved considerably, however to not the extent of the Katadyn BeFree Gravity.
The rationale I’m recommending the Platypus GravityWorks over the Katadyn BeFree is that it’s set as much as be a set-it-and-forget-it. You possibly can replenish the soiled bag, arrange the filter, after which go away for nevertheless lengthy you want as you attend to different camp chores. With the opposite gravity filters right here, you’ll want to watch extra intently, swapping out a reservoir because it begins to replenish. Nonetheless, in case you don’t thoughts babysitting your gravity filter, then the lighter weight and quicker move of the BeFree could be a better option for you.

A gravity filter that may take away viruses: this one is past spectacular. Sadly, it additionally comes with some drawbacks. The most important is that its tiny pore dimension (.02 in order that it could catch these microscopic viruses) signifies that the filter slows down pretty quickly, even when the water sources it’s coping with aren’t overly difficult. The MSR Guardian Gravity handles this by constructing a backflushing mechanism into the filter itself. You merely stopper the principle filter, and unstopper the backflush mechanism. After a couple of minutes you turn again and proceed in your approach. This works nicely, however I used to be shocked by how typically I needed to do it — in contrast to the remainder of my filters, which have been solely backflushed after the second and third rounds, I backflushed this one after the primary spherical and was rewarded with a move that was quicker than what I had began with. For many water sources, it is best to plan to backflush each 3 to 4 liters — extra typically if it’s exceptionally soiled, as I ended up doing. Backpackers ought to notice that this one can be pretty heavy in comparison with different gravity filters I’ve examined.
If the water supply you’ll be utilizing is contaminated with viruses, and you are feeling strongly about avoiding chemical therapy, it is a nice hands-free choice. For most individuals, it’s possible overkill. However the truth of its existence is a testomony to the problem-solving creativity of the parents at MSR.

Of the three gravity filters in my check, the Katadyn Gravity BeFree had the quickest move each when initially unboxed and after the ultimate stage of testing. It was additionally lighter than the opposite two fashions in my check by a number of ounces.
One small, however doubtlessly vital, distinction between the Katadyn BeFree and the Platypus GravityWorks and LifeStraw Peak Collection Gravity is that the hold strap will not be connected to the water flask when the gravity is first unboxed. This strap, nevertheless, shouldn’t be thought of non-compulsory. The bail deal with on the high of the water flask will not be meant to be slung over a department, and is just too small for the department dimension that you’d want for the filter to be safely suspended.
One other distinction between the Katadyn Gravity BeFree and the opposite two filters in my check is that it’s not designed for backflushing (which might harm the fibers), however the filter may be cleaned by rigorously swishing it in water. Whereas the filter did seem cleaner after I swished it, oddly, the time it took to filter a liter of water elevated by a minute (I reran this check to verify the outcomes).

In the event you seek for “backpacking water filter” on Amazon, you’ll nearly actually come throughout the Waterdrop filter. This model isn’t as widespread within the backcountry, as the corporate’s major focus is on water filtration for the house, however the mannequin that I examined is designed for backpackers to make use of interchangeably as a gravity filter or squeeze bag. For simplicity’s sake, I examined it as a gravity filter.
Earlier than we go even additional, please don’t purchase this water filter for touring within the backcountry. Their web site says they take away 99.99 p.c of micro organism. Whereas that sounds spectacular, the usual is for 99.9999 p.c. You’re susceptible to sickness in case you depend on this water filter to guard you from one thing like E.coli.
That the Waterdrop can’t be relied on for precise filtration is just one if its drawbacks: it’s additionally a rattling sluggish filter. It does get quicker once you backflush it — surprisingly, move was quicker after my first backflush than it had been initially. Nonetheless, you want working water to do that, which isn’t all the time accessible. One other sensible challenge is that the plastic stopper on the tube working from the filter was not efficient at truly stopping the water’s move.
In the event you’ve received nothing higher to do than wait round for an hour or two whereas all of your water finishes filtering, after which additionally deal with it with chemical substances so that you’re truly shielded from micro organism and protozoa, this won’t hassle you an excessive amount of. However most backpackers have higher issues to do. In the event you’re after a gravity filter, go for both the Katadyn BeFree (in case you worth light-weight) or the Platypus GravityWorks (in case you worth comfort). In the event you’re after a squeeze bag, seize a Sawyer Squeeze, which is simply nominally costlier.

For backpacking water filters, safety towards viruses, together with norovirus and rotovirus, sometimes comes with a tradeoff—if you’d like a filter with a sufficiently small pore dimension to weed these suckers out, you higher be ready to place in some critical elbow grease. However the MSR Guardian manages the hat trick, filtering out viruses at a quick move charge with the identical, and even much less, elbow grease required as from different filters.
A part of this attributable to a singular characteristic to the MSR Guardian: as a substitute of directing the entire water out by the underside of the filter with every pump, a portion of the water is directed again by the filter—primarily backflushing the filter with every pump. Throughout testing, this meant that the filter had the identical efficiency over the past spherical of testing because it did throughout the first: forty-five seconds for a liter of water.
I used to be additionally impressed with how simple the MSR Guardian was to make use of straight out of the field: after it had been unmoored from its packaging, I merely unscrewed the cap on the underside of the filter, plopped the consumption filter into my pool of water and began filtering water. Moreover the prefilter, which could be a bit tough to place within the water supply attributable to a 90-degree angle, the most important draw back to the Guardian is its price, and its weight: it was about ten occasions as costly as different comparatively quick filters (the Katadyn BeFree, Platypus QuickDraw, and Sawyer Squeeze) and 5 occasions as heavy. However in case you’re on the lookout for a no brainer filter that may take away the complete spectrum of micro organism, protozoa, and viruses out of your water with principally no upkeep required, then that is the filter for you.

The Katadyn Pocket was, together with the MSR Guardian, probably the most costly filters I examined. Whereas the Pocket struggled with the testing protocol, taking up 11 minutes to filter a liter of water after the ultimate spherical, the place it actually shone was after I had cleaned it. This filter was 10 occasions quicker after cleansing than earlier than, which means that, if taken care of accurately, might final for a few years.

I’ll admit: I broke a Katadyn Hiker Professional years in the past after utilizing it in water containing glacial runoff. So I wasn’t shocked to see that it struggled with that portion check, needing over 4 minutes to filter a liter of water. And whereas this wasn’t part of my testing protocol, the sheer problem of all of the tubes and nozzle caps for this filter makes it a non-starter for me.

Whereas the Katadyn Vario clocked in a really spectacular trip of the field and within the first two rounds of testing, it struggled within the closing spherical of testing, after being subjected to glacial silt. Worse, after I backflushed the filter (following producer directions), it stopped working completely.

Given the ubiquity of the MSR MiniWorks within the backcountry, I used to be shocked at its poor efficiency in my check. It was by no means a very quick filter in comparison with different choices, and it clocked one of many worst occasions throughout the check on the wetland earlier than fully breaking whereas I used to be filtering glacial runoff. I’ve little doubt this filter was probably the greatest in its class when it was initially launched, nevertheless it has since been eclipsed by different, cheaper choices, together with the Platypus QuickDraw from MSR’s sister firm.

There are many backpackers who refuse to take care of the trouble of any sort of backpacking water filter, preferring as a substitute to go for chemical remedies. Of those, the preferred is Aquamira. The most important motive is solely that, or all of the chemical therapy choices accessible, Aquamira has just about no style. In the event you’ve ever tried to go a whole journey with bleach or iodine-flavor water, what a sport changer that’s.
In contrast to bleach and iodine, nevertheless, the method for utilizing Aquamira is just a little concerned. The therapy is available in two separate bottles, which have to be rigorously blended collectively within the bigger of the 2 bottle caps. You then go away it sitting for 5 minutes, so the chemical response can get began, earlier than including it to your water bottle. Twenty-five minutes later, you might be able to hydrate.
For some backpackers, this tedious process and lengthy wait is a small worth to pay to keep away from the pitfalls (primarily, clogging) of conventional filters. If that sounds such as you, then Aquamira is a wonderful and fairly inexpensive choice.

Steripens, the preferred type of UV water therapy for backpackers and backpack hunters, are one of many strangest water therapy choices in the marketplace. Whereas chemical therapy and water filter choices make some sort of intuitive sense, the eerie glow of UV therapy appears nearly magical. For some folks, that is interesting; for others, it’s a nonstarter.
Which will get a bit on the coronary heart of the expertise of utilizing a SteriPEN. I used the unique model of the SteriPEN for years and have become pretty acquainted in that point with its pitfalls: don’t pack it away moist, heat it up earlier than utilizing it in particularly chilly water, watch the sensors rigorously when submerging. By rigorously following these guidelines, we might get about as a lot reliability out of our SteriPEN as customers of the squeeze bag filters have been getting.
On our testing journey, I handed off this newest model of the SteriPEN to one in all our testers whereas going to place away my tent. Once I got here again, quarter-hour later, she nonetheless hadn’t managed to filter a liter of water. I watched her fifth try and see if I might troubleshoot what was going fallacious, however I couldn’t see why she was getting error readings (or recall within the second what the totally different flashes of coloration meant).
Then I attempted it and it labored completely. This about sums up most individuals’s expertise with SteriPENs. After they work, it’s like magic. After they don’t work, you’ll wish to pull your hair out. In the event you do go this route (it’s the solely non-chemical therapy at this weight that’s efficient towards viruses), then make sure you try it out extensively at dwelling and take a backup water therapy methodology alongside for just a few journeys till you might be comfy with it.

For years, I carried a bottle of iodine in my first-aid package. I nearly by no means used it (iodine tastes horrible), however within the occasion that my water filter broke, I wished to have one thing surefire available. Whereas immediately’s backpacking water filters are far more dependable than the previous pump fashions of yore, carrying just a few tabs of backup water therapy nonetheless brings me peace of thoughts on longer, extra distant backcountry treks.
Like Aquamira, Aquatabs take about half-hour to take impact, though no premixing is required right here. However whereas Aquamira has no discernible taste, there’s a slight chemical taste that goes together with the Aquatabs (though our testing group didn’t discover that they’d the identical unpalatable taste as different evaluations). Whereas that is solely a minor concern in a real survival situation, long-term use of Aquatabs might lead to particular person backpackers inadvertently hydrating lower than is perfect for his or her surroundings.

Is there any extra basic water therapy choice than iodine? However, after all, there’s a motive this one has fallen out of favor: it tastes horrible and, long-term, it’s horrible for you.

How I Examined Backpacking Water Filters
Earlier than I even started testing, I interviewed the parents at MSR, LifeStraw, and Katadyn about how they assure that their filters are certainly eradicating micro organism and protozoa (and within the case of some of them, viruses). All of them have interaction in rigorous testing, utilizing EPA or NSF requirements, each in their very own services and thru third events, like BCS Laboratories out of Florida.
I visited the MSR facility the place they confirmed me the lab the place they not solely develop E. coli micro organism, but in addition a virus that assaults E. coli, to check the efficiency of their Guardian filter. The thoroughness of this testing will not be one thing that may be simply replicated within the pure surroundings, the place the pre-existing ranges of micro organism, protozoa, and viruses are unknown. As such, my testing didn’t have a look at how nicely the filters handled micro organism, protozoa, and viruses, as a result of all of the filters on this evaluation use EPA or NSF requirements.
One thing else that you just’ll typically see on the packaging of backpacking water filters is the variety of liters per minute that they filter. This quantity, nevertheless, solely displays what the filter is able to doing proper out of the field—not after you’ve taken it out on a few backpacking journeys—or 20. The manufacturers after all are testing to make sure that the filters can face up to a sure degree of grit, nevertheless it’s uncommon to be taught what the move charge of the filters are after they’ve been uncovered to some less-than-ideal water sources, not to mention how a lot grit and sediment and muck a filter can take earlier than it craps out fully. So my testing checked out what circumstances the backpacking filters can face up to and nonetheless return an affordable (or any) move charge.
To begin, I known as in or bought the preferred backpacking water filters accessible, together with corresponding fashions from their rivals. Earlier than I started testing the filters out within the discipline, I first timed how lengthy it took every to filter one liter of water out of the field. Usually, these occasions corresponded to the marketed occasions of the producers. Throughout this course of, I additionally famous how difficult the filter setup was out of the field.
Then I took the filters to a public seaside in Bellevue, Washington, which had been closed attributable to excessive ranges of fecal matter (3 times greater than what’s thought of protected for swimming). Right here I filtered 5 liters of water by every of the filters in my check.
Along with the recorded excessive ranges of fecal contamination, the water was additionally pretty scummy.
On the finish of the primary spherical of testing, I took the filters again dwelling and measured how lengthy it took to run a liter of water by every, and the way that in comparison with the out-of-the field check. Usually, there was a noticeable, if not vital, impact on the size of time it took to filter one liter of water. Satirically, some filters measured a quicker time on the finish of the preliminary spherical of testing than they’d in the beginning; my impression is that that is the results of my turning into extra environment friendly at utilizing the filter with apply.
The second spherical of testing happened at Narbeck Wetland Sanctuary, simply north of Seattle, Washington. It is a classically lovely swamp, with loads of water however all of it gunked up by the filth and tannins and life teeming beneath the floor. Right here we’d see how nicely the backpacking water filters responded to the mucky water sources that these within the backcountry are generally pressured to resort to. I filtered three liters by every of the water filters at this website, after which headed dwelling to document how lengthy it was taking every water filter to push water by.
Unsurprisingly, a number of the filters have been actually struggling on the finish of this check. For the filters that took over two minutes to course of a liter of water, I adopted producer instructions to backflush (pushing water backwards by the filter) or in any other case clear the filter, noting that some filters couldn’t be cleaned or backflushed.
Then I retested these filters (the outcomes are famous in a parenthetical within the under desk) to see how efficient cleansing the filters was at establishing water move. The 2 filters that took over 5 minutes to course of a liter of water on the finish of the second spherical of testing, the LifeStraw Peak Collection Gravity and the RapidPure Air purifier+, have been faraway from the check at the moment.
The ultimate testing website was the Puyallup River, accessed on the city of Orting, Washington. At first look, the Puyallup seems like another muddy river. However the Puyallup will get its coloration from glacial sediment, a particularly advantageous silt that stays suspended within the water. This sediment additionally works its approach into the inside workings of filtration techniques like no person’s enterprise. Nobody would select to filter this type of water until there was no different choice accessible; generally, there is no such thing as a different choice accessible.
Unsurprisingly, lots of the filters struggled with cleansing three liters of water throughout this check, and one (the MSR Miniworks EX) was faraway from testing because it merely clogged up and stopped working. On the finish of this spherical of testing, the filters have been measured to see what their move charge was. Subsequent, the filters, the place potential, have been additionally backflushed, or in any other case cleaned, after which had their move charge measured once more. (Observe that a number of the occasions for this stage have been once more quicker than the preliminary move.
Whereas I made an effort to standardize the quantity of elbow grease I used to be placing into every filter throughout the timed check, it’s clear that I used to be placing extra elbow grease into the ultimate stage of testing than I did straight out of the field). The ultimate step of this check was to reweigh every of the filters to evaluate how their weight had modified from the beginning of testing. I pumped out as a lot water as I might from every filter after which positioned the filters in an enclosed room with a dehumidifier to take away extra water (with out drying out the filter elements themselves). After an hour, I took them out and reweighed them.
In April 2025, I put seven new merchandise by my testing protocol. For the primary check — micro organism seaside — I headed to essentially the most polluted lake in my space on the time, Cottage Lake, which was closed to swimming attributable to algae bloom and subsequent cyanotoxins polluting the water. For the wetland portion, I once more returned to Narbeck Wetland Sanctuary, which was as murky as ever. What was considerably much less murky was the Puyallup River close to Orting, WA. Whereas the river water was extraordinarily silty in my unique testing, the spring run off ran a lot clearer than I had anticipated. Sadly, this meant that testing circumstances weren’t difficult sufficient to offer helpful data. I’ll be taking these filters again in late summer season for a contemporary check in correct silty circumstances.

Further testing was executed on a number of chemical and UV therapy choices as a part of the inaugural Outside Life backpacking gear check.

Issues to Think about Earlier than Shopping for Backpacking Water Filters
Micro organism, Protozoa, Viruses, Heavy Metals, and PFAS
The place as soon as backpackers solely involved themselves with giardia, immediately there are a number of different considerations, together with norovirus, heavy metals, and PFAS. Let’s check out which backpacking water filters can deal with which sorts of contaminants, and once you want virus and heavy metallic safety.
All the backpacking water filters I examined take away micro organism and protozoa. That’s nice information as a result of two of the commonest backcountry water contaminants are E. coli (a micro organism) and giardia (a protozoa). In hottest backpacking places by the USA, that is all you’ll want safety towards.
Viruses
The most typical viral contaminant is norovirus. Whereas that is sometimes considered a frontcountry contaminant, it could (not often) happen in water sources within the backcountry. That is nearly all the time the results of human feces contaminating water sources.

Heavy Metals
Whereas heavy metals do happen naturally within the surroundings, contamination is usually the results of trade. Heavy metals differ from micro organism, protozoa, and viruses because it’s unlikely to hurt you throughout your journey, however accumulation in your physique may end up in damage to your organs.
A filter alone — even a complicated one just like the MSR Guardian — can not take away heavy metals. Backpacker water filters that take away heavy metals sometimes use activated carbon. Whereas these filters are considerably efficient at eradicating heavy metals from water sources, they aren’t good: actually nowhere close to the 99.9999% ranking of a typical filter towards the likes of micro organism and protozoa. Your first line of protection is to not drink water from sources recognized to be contaminated with heavy metals. However whether it is unavoidable, or unclear if contamination is a matter, then these will provide some protection.

PFAS
Whereas PFAS contamination has been a difficulty for a few years, it’s solely not too long ago that backpackers have realized that backcountry water sources could also be in danger. That’s as a result of, in contrast to different contaminants, rainwater can include PFAS. At current, there are only a few backpacking water filters that may take away PFAS; nevertheless, the fact is that almost all backcountry sources won’t be contaminated, or contaminated at such low ranges as to not pose vital hurt to human well being. It’s best to take further care round water sources which are close to navy bases and wildland firefighter coaching services. That’s as a result of previous use of AFFF firefighter foam led to intense PFAS contamination.

Weight of the Finest Backpacking Water Filters
Whereas it may be tempting to seize the most important, baddest water filter on this record (the MSR Guardian), the fact is that almost all backpackers shall be higher served by carrying one thing lighter weight. The extra you may maintain your pack weight down, the farther you’ll hike and the extra enjoyable you should have.
Filter Upkeep for the Finest Backpacking Water Filters
As my testing exhibits, cleansing out your filter could make an enormous distinction in efficiency. In the event you don’t wish to shell out for a brand new filter each season, make sure you learn the instructions and maintain onto any plungers or different needed items. Until you’re going on an exceptionally lengthy hike or count on to filter solely glacial silt, you possible received’t have to convey these items with you on every hike.
FAQs
Backpacking water filters can price as little as $25 to as a lot as $400. A lot of the distinction in price displays the long-term sturdiness of the filter, in addition to their skill to deal with extra complicated water high quality issues, together with viruses and heavy metals.
The query of whether or not you want a water filter or air purifier for backpacking is, to an extent, concerning the degree of danger you might be keen to tolerate. Within the excessive alpine of a nationwide park, as an illustration your odds are low, whereas in case you are sharing a water supply with livestock in a nationwide forest, the percentages improve significantly.
As a result of the implications of contracting a waterborne sickness like giardia or cryptosporidium may be so extreme, and each the price and weight of low-profile filters just like the Sawyer Mini Squeeze, Platypus Quickdraw, and LifeStraw Peak Collection will not be a burden for many backpackers, I like to recommend all the time carrying one in your hiking backpack and treating all of your water sources with it. In case you are uncertain as as to whether you want a water air purifier—which may also take away viruses like rotovirus and norovirus—contact the land supervisor the place you intend to journey for extra details about the waterborne contaminants sometimes discovered there.
Even immediately, it’s pretty widespread to see a blanket recommendation to all the time boil your water when out within the backcountry. The rationale for that is easy: most backpacking water filters don’t take away viruses, whereas chemical therapy strategies aren’t efficient at neutralizing protozoa like giardia and cryptosporidium. Boiling water, alternatively, does all of it. The difficulty with this advice is that boiling water will not be solely time consuming, however may also require you to usher in an extra of gas or a backpacking stove if the place you might be touring doesn’t have choices available. Even in case you do plan to boil all of your water, carrying a light-weight filter is a crucial backup to have within the occasion that your gas sources run out.
Closing Ideas on the Finest Backpacking Water Filters
The perfect backpacking water filters produced by respected manufacturers like MSR, LifeStraw, Katadyn, Platypus, RapidPure, and Grayl present wonderful safety towards waterborne illnesses within the backcountry. Which filter is best for you will rely largely on whether or not you prioritize price, weight, or long-term sturdiness.
