Ready for the Backcountry
The ultra-light, easily packable Sawyer MINI water filter fits in the palm of your hand and weighs just 2 ounces — making it ideal for ultralight backpacking and camping, as well as emergency preparedness.
Each MINI comes with a durable, collapsible 16-ounce reusable squeeze pouch that rolls up when empty, so it won't take up space in your pack.
Filtered Water Anywhere
The reusable 0.1 absolute micron MINI water filter produces clean water from freshwater lakes, rivers, and streams, as well as faucets in your home or hotel room while traveling (domestic and international).
The MINI also comes with a straw that enables you to drink filtered water directly from a water source.
To start filtering water, simply fill the squeeze pouch with water from your water source, then screw the MINI filter onto the pouch and start drinking right from the MINI or squeeze into a water bottle to share with others.
The MINI also screws onto water or soda bottles with a standard threaded top, and you can attach inline on a hydration pack to filter water from a bladder (sold separately).
Sawyer's International Mission
Sawyer believes everyone deserves access to clean water — from hikers in the backcountry to indigenous people groups in the remotest corners of the world.
For over 10 years, Sawyer has been working with a variety of charities and churches who are on a mission to make a long-lasting impact in the lives of those around the world without access to clean drinking water.
High Performance Water Filtration
Hollow Fiber Membrane
Sawyer’s water filters are comprised of tiny hollow fiber membranes that allow water to enter into their core through tiny micro-pores.
Thicker fiber walls combined with a smaller inner diameter make Sawyer fibers 75% stronger* than typical hollow fiber membranes, giving you a fast flow and enabling the filter to be continually backwashed forcefully to restore up to 98% of the original flow rate.
* Clean Water Institute of Calvin University; July, 2018
0.1 Absolute Micron Filtering
Each Sawyer water filter features 0.1 micron absolute filtration, meaning there is no pore size larger than 0.1 micron in size.
This makes it nearly impossible for microplastics, harmful bacteria, protozoa, or cysts like E. coli, Giardia, Vibrio cholerae, and Salmonella typhi (which cause Cholera and Typhoid) to pass through.
Sawyer's hollow fiber membranes are fully encased and sealed to keep them protected. When fibers are not enclosed, physical damage of exposed fibers could allow harmful pathogens to pass through.
Tested 3 Times
Every Sawyer filter is performance tested three different times during the manufacturing process for your protection.
Testing occurs after the fiber element construction and twice after casing assembly to ensure no harmful pathogens leak through the sealed case or internal O-rings.

A lightweight, versatile personal filtration system, the second-generation Sawyer MINI Water Filter fits in the palm of your hand and has a total field weight of just 2 ounces. Perfect for everything from camping with the kids to traveling abroad where tap and bottle water can't be trusted, the tiny MINI provides 0.1 micron absolute filtration for clean drinking water on the go — filtering out bacteria, protozoa, and microplastics. The MINI filter removes 7 log (99.99999%) of all bacteria (like salmonella) as well as other harmful bacteria which causes cholera and E. coli and 6 log (99.9999%) of all protozoa such as giardia and cryptosporidium. These removal rates equal or exceed other filter options. EPA guidelines allow ten times more protozoa left in the water than Sawyer MINI filters allow. The MINI also filters out 100% of microplastics. The MINI 0.1 micron absolute filter houses a cluster of micro-fibrous tubes which use similar technology found in medical dialysis. As water passes through the side walls of the tubes, harmful bacteria and protozoa are trapped on the outer walls so you can be confident your water is safe to drink. Great for outdoor recreation, hiking, camping, scouting, domestic and international travel, and emergency prepping, the Sawyer MINI gives you a number of ways to access clean water. Attach it to the included drinking pouch, use the included straw to drink directly from your water source, connect it to hydration pack tubing (sold separately), or screw it onto standard disposable bottles (28mm thread). Since 1984, Sawyer Products has offered the best, most technologically advanced solutions for protection against sun, bugs, water, and injuries — everything from first aid kits developed for wilderness to point-of-use water filters that filter contaminated water to levels cleaner than U.S. bottled water.

Sawyer company- fix your O rings on the mini and you go from a 1 star to a 5!
A simple hack to replace or substitute the bag that comes with it. This filter screws onto either a 700 ML or 1 Liter SmartWater bottle. The sports cap on the 700 ML is the perfect size to push the outflow end of the filter into and is tight enough to support the weight of a full, 1 L bottle. Just squeeze the air out of the bottle on the outflow side and lean it against a tree or rock to gravity feed or you can squeeze the inflow bottle to speed things along. Make sure you cover the washer with your finger when shaking out the filter so it doesn't fly off and get lost. A 5/16" ID x 1/2" Yellow Plastic Screw Protector (made by Hillman and available at Lowe's for $0.92 for a 3 pack - Model # 881039, hardware section where the metal bolts, washers, etc are in the steel drawers. They will be marked with Hillman on them.) will fit over the inflow nipple of the Sawyer Mini Filter to prevent leakage and keep dirt out of the filter when it's stored in your pack.
First Pic is a 1 L bottle that is full, being held by the filter pushed into the sports cap. The second pic (sorry for the blur) is filling a 1L bottle with the air squeezed out of it. The third pic shows my finger over the washer when shaking out the filter so it doesn't get lost. Last pic is of the Hillman cap and package.
I would not recommend this filter, and will be looking to another brand in the future.
I bought this filter a few months ago[ to add to a survival/camp pack and have since filtered about 40 liters of water through it. This filter cleans anything from questionable garden hose water to murky lake water into perfectly clear and crisp to the taste drinking water. At first, I was skeptical of course. Who would think that you can turn brown, dirty water into clean, perfectly safe water with just such a small, affordable filter? But rest assured, this filter is a powerhouse and continues to go above and beyond.
One tip I have for easier and more bulk filtration is to pick up a Platypus Plastic 2L Water Bag (Link below). It's less than $10 just like the bottle you get with the filter except it allows you to filter 70oz rather than 16oz. I also got a grommet kit from a local craft store and placed 2 grommets in the corner of the bag in the seam. I then ran a 1 foot section of para-cord through the grommets which allowed me to hang the bottle on a tree branch or any other convenient location. This way you can let gravity do the work and continue on with your camp chores. I was able to filter 2 liters of water this way in around 10 minutes.
One word of caution: Sawyer claims that you can filter 1,000,000 gallons of water through this filter (you're probably more likely to lose the filter before you get to that point) regardless, cleaning is a must. It will greatly extend the life and quality of your filter and water. After every filtration session I recommend flushing the filter with clean water using he provided syringe. Don't be afraid to really shoot the water in there, you're only helping your filter.
All in all this filter was a GREAT buy. I don't think you can find a better filter, especially one under the $100 mark!
Also, the cap easily breaks or falls off and gets lost. I lost 1 cap and 2 snapped off, and didn't find anywhere where I could purchase just the caps and not the entire filter all over again.

So why did I buy the Sawyer Mini (SM)? Well, I was interested to try a different water filtration system to compare it with the DTT I normally use.
What are the advantages of the SM:
1) It is much lighter than the DTT (SM = 53g vs DTT = 138g including bottle) so is good just to keep as a back up in your back pack when out trekking (DrinkSafe also produce a lightweight 'Waterstraw' 40g currently £16.95 which has superior filtering to the SM but is not as versatile)
2) Versatility i) You can use it like a filter 'straw'. It actually comes with a plastic straw that you just place in the water and drink filtered water.
ii) You can screw it into many different bottles like coke bottles or the 16oz bag that it comes with (this 500ml bag is way too small for practical use and Sawyer should provide a bigger more usable bag). It also combines well with collapsible water bottles such as the Evernew bottles. It also screws into my Platypus bottles but water does leak through the thread when under pressure which is not good for potential cross contamination. iii) You can also use the SM as an in-line water filter with back-pack water bladders.
3) The SM can be flushed through using a syringe that comes with it. This means that you can keep the filter clean and filtering pretty much forever and Sawyer claim that the filter is good for 100,000 gallons of filtering which is incredible. This is a big advantage over the DTT which can't be easily flushed through. You therefore have to be careful with the DTT not to get too many particulates in your water and clog up the filter. You will never be at risk as the DTT will always filter out contaminants but will eventually clog up. Nevertheless, Drinksafe claim it is good for 1600 litres and I have had bottles for several years and they haven't clogged up yet (I am careful not to get too many particulates in the water though).
What are the disadvantages of the SM:
1) SM DOES NOT FILTER OUT VIRUSES AND CHEMICALS - this is one MAJOR disadvantage of this water filtration technology compared to the DTT in my opinion. For highland water courses where farm chemical run off and viruses are less of an issue this is not a problem. However, I want a water filter that is good for both highland and lowland water courses - ie. wherever I happen to find myself. In this case the DTT is far superior.
The above comparison means that I couldn't use the SM as my only water filter unless I know that I'm only going to be in higher areas with no agricultural run off. The DTT will therefore remain my default and most usable water filter when out trekking and the one I would recommend to people looking for a water filter that filters out pretty much everything a British water course can throw up. However, I will probably take the SM along with the DTT when I'm wild camping to use it to filter out particulates when decanting water into my DTT. This will prevent my DTT from clogging up knowing that I can flush out all the accrued particulates from the SM later using the syringe.
In conclusion, if I had to buy just one water filter, I would buy the Drinksafe Systems Travel Tap Pull Top. Used in combination, the Sawyer Mini can be used to provide particulate free water for the DTT. This is how I will use them together. The DTT wins on what it will filter out from the water, whereas the SM wins on versatility and flushability. The DTT wins overall in my opinion as the filtering of viruses and chemicals is my most important concern with a filtration system. Hope the comparison is helpful to potential buyers.
L'eau ressort clair et limpide, sans odeurs.
Mais justement: ATTENTION au faux sentiment de sécurité !!!!
En effet, si il filtre bien les bactéries, il ne filtre pas les virus, plus petits (grippe aviaire,...).
Un traitement au chlore est hautement recommandé avant de boire si on veut être sûr et certain (2-3 gouttes d'eau de javel nature/1 litre eau).
De même, il ne débarrasse pas l'eau des métaux lourds (plomb,...) et autres produits chimiques (engrais, ammoniaque,...).
Il faut un filtre au charbon actif en complément.
Donc ne pas tenter de boire dans une eau croupie, proche de bétails/animaux/agriculture,... sans traitement complémentaire.
Im Bereich der Filter gibt es Elemente mit Aktivkohle, Keramik, Glasfasermatrix und Kapillarröhren.
Der Sawyer Mini ist eigentlich eine Kunststoffröhre mit zwei verklebten Enden...im Innern die gelegten Kapillarröhren-in deren Schnittseiten das Wasser eindringt und am anderen Ende wieder(etwas "sauberer") heraus....also ganz einfach, primitiv und natürlich mit Gefahren verbunden-so fehlt ein Überdruckventil, nirgends kann man den Zustand der Kapillare begutachten(z.B. Frost lässt diese unbrauchbar werden!) so muss man immer selber entscheiden, wann und ob man ihn ersetzt....auch kann das ganze Element verkeimen....
Reinigung: Genauso wie jeder andere Filter muss er gereinigt werden...hierzu hat man eine große Einwegspritze zur Verfügung-mit dieser wird rückwärts Wasser durch den Filter gedrückt, bis das Wasser sauber ist und ein guter Durchfluss wieder gegeben ist! In der Praxis klappt dies natürlich nicht vollständig und die änfänglich guten Durchflusswerte verringern sich merklich! (aber dies haben auch andere Filter z.B. von MSR und Katadyn)
Bedienung: Den beigefügten Beutel mit Wasser befüllen, ihn aufschrauben und das Wasser hindurchdrücken(nicht zu fest, um durchdrücken von Erregern und Beschädigung des Beutels zu vermeiden)
Erweiterungstipp: Von Katadyn, Platypus und anderen Herstellern gibt es Aktivkohlefilter, die man hinter den Sawyer schalten kann...Aktivkohle wirkt durch Bindung (bis zur Sättigung) und verbessert den Geschmack und KANN Giftstoffe filtern (dies ist aber stark limitiert und nur ein primitiver Erfolg ist zu erwarten, denn Art und Menge und wiederum die Menge an Kohle und deren Sättigung sind nicht wirklich seriös zu überprüfen)
Meckern: kein "Verfallsanzeichen",(auch bei Beschädigung durch Frost,etc) Durchfluss wird durch Verschmutzung dauerhaft verringert (trotz Reinigung/Rückspülung), kein Überdruckventil und die Beutel haben eine sehr unterschiedliche Lebensdauer (von 1 Tag bis 3 Jahre hatten wir schon "alles") im innern kann es zu einer Verkeimung kommen, da er nicht silberbehandelt ist. Durch die Konstruktion ist die Gefahr groß-sein Wasser zu kontaminieren (nasse Hände, herabtropfendes Wasser,...)
Fazit: Günstig, leicht, kompakt und Hilfsmittel zur limitierten Reingung von Wasser und zur Beruhigung der "inneren Sorge"....wer hier eine Kläranlage im Taschenformat erwartet....ist fern der Realität...alles kann-nichts muss....so kommt es ja auf die Kontaminierung an und deren Art ( Viren die nicht an Wirten haften-gehen ungehindert durch den Filter) und chemisches kann er auch nicht filtern...in der Summe ist er "besser als nichts" und in Verbindung mit Entkeimungstabletten, Aktivkohle-Ergänzung und der Möglichkeit noch abzukochen hätte man den größtmöglichen Effekt auf Tour. Vom Durchfluss gefällt mir das größere Modell (SP129 und der Nachfolger SP2129 besser) Unbedingt Reservebeutel einstecken-notfalls gehen auch Getränkeflaschen (Einweg)
My plan was to use it on walking trips to reduce the weight of my bag. However, I have found it so good at improving the taste of the tap water in my house that I use it to fill my water bottle for the day. I have conducted a taste test on my wife who wouldn't usually approve of such purchases. However, she picked the filter water as tasting better and commented on the crispness of the taste.
It is very simple to use, simply fill the pouch from any water source, attach the filter and squeeze. The flow rate is pretty quick considering what it is achieving. It is also very light but appears to be very sturdy.
27th April Update - You must be careful to ensure this product doesn't experience freezing temperatures. I had left mine in the back of the car over the xmas period. When using it in Feb I started to doubt its filtering ability as it appeared to let small visible bits through. This might have been in my head as it made me stress out a little. However there was an element of doubt that prevented me being able to use it. I have binned it and since brought another. From now on it will be stored indoors!
I am currently looking to find a bottle that it attaches to and understand that a smart water bottle is what I should be looking for.
I very much recommend this product for anyone going abroad wishing to make their water safer and to use on day and multiday hikes. It is difficult to go wrong considering the relatively low price.
Am besten direkt sauerstoffbleiche zum Reinigen dazu kaufen (gibts bei Müller für 50% von dem was es hier kostet)
Die Viedeos von Sacki kann ich hier sehr empfehlen aber die wird ja sowieso jeder gucken der sich für den Filter interessiert.
Die Kritik an der Durchflussmenge kann ich nicht verstehen, ich bekomme 1L bequem in ~1,5 Minuten durch!
Wer draußen pro Tag keine 5 Minuten Zeit für Wasser hat, der macht irgendwas falsch!
Ein Tipp noch: zum rückspülen eignen sich die Deckel die bei diesem komischen Geschmack-Wasser von Active- O2
Dann muss man auf Tour die Spritze nicht mitnehmen.
Ein Hinweis: im Winter ist die Nutzung problematisch, er darf nämlich keinesfalls einfrieren das ist aber bei allen hohlfaser-membranfiltern der Fall.
Noch zum wasser-sack: ist wie Sacki sagt als verbrauchsprodukt anzusehen.
Bei sachgemäßer Handhabung wird aber auch er lange halten und die Standard PET Flaschen passen ja auch.
Für 25 € konkurrenzlos da er ja theoretisch ein Leben lang halten soll
(Ich würde in trotzdem nach spätestens 10 Jahren austauschen).
Mängel an Material oder Verarbeitung kann ich nicht nach 6 Monaten der Nutzung nicht erkennen.
D’abord son système de filtration est de 0,1 micron contre 0,2 microns pour la plupart des systèmes du marché. Cette différence est notable car elle permet la filtration de toutes les bactéries et d’un très grand nombre de virus (même si certains sont plus petits que 0,1 micron, un virus ne peut vivre que s’il est fixé sur un corps étranger, de ce fait ils dépassent généralement les 0,1 micron).
De plus, sa capacité de filtration est largement supérieure à tout ce que l’on peut trouver sur le marché ( généralement entre 5000 et 10000 l). Sawyer vous permet largement de pouvoir en situation de survie apporter de l’eau filtrée a vous et votre famille pour toute votre vie. Il est donné pour 380 000 litres d eau filtrée ( au cours de votre vie vous en consommerez 40 000 litres) Et ce avec un seul filtre à condition qu’il soit bien entretenu.
Pour ce qui est du gout de l’eau, il est largement buvable. Même si l’eau n’est pas clair a la base elle ressort limpide.
Attention cependant la filtration n’est pas complète en cas de contamination par métaux lourds, pensez à compléter le procéder de traitement de l’eau avec un filtre au charbon actif.
De même, pour que la filtration soit complète et qu’il n’y ait plus de virus pensez à la compléter par une filtration uv, chimique (micropur ou javel: entr 1 et 5 goûtes par litre) ou ébullition
Si vous trouvez mon avis utile n’hésitez pas le faire remonter.
Considering its small size and weight the Sawyer can easily be stored in a backpack and taken with you on any adventure.
Always pay attention to where you are getting your water from, regardless of whether you are using a water filter. Read the instructions to be on the safe side and make sure you understand what the filter can and can not filter from water.
Went for a wild camp up on Dartmoor, took no water with me but I did take two bottles of Coca Cola after reading somewhere that the water filter screws onto the bottles. Before I headed off I ran some water through it at home on the recommendation of someone I know and all I took with me was the filter itself.
Using it was a breeze. Filled an empty Cola bottle with river water (the water was brown due to the peat!) screwed the filter on and squeezed the bottle gently. I was amazed at how fast it went through without feeling like it was being pressured or forced through faster than I should have - in other words, it handled it no problem.
Drank quite a bit in the form of cups of coffee and two weeks later I've not had any upset stomach problems.
-il n'y a pas d'odeur de chlore après filtration contrairement à ce qui a pu être dit
-le filtre s'adapte très bien sur les bouteilles, j'ai testé sur une bouteille de Perrier, de Carola et de Coca-Cola et elles se vissent parfaitement
-effectivement la notice n'est qu'en anglais, mais si vous avez internet pour commander le filtre, vous avez accès à google traduction, et de toute façon l'utilisation du produit est très simple
2. Packaging - Filter was fairly lightly packaged on arrival with not piles of directions or extra garbage to get rid of - Basically three pieces of card stock paper and a plastic case to contain it. Thank you for not over-packaging - this means a lot to me.
3. Size & Weight - Impressive. Filter is roughly 3 times the size of a tube of chap-stick. It fits in the palm of my hand. It's weight is borderline negligible considering it's purpose. The plunger is absurdly large at about twice the size of the filter itself, so it seems sort of silly. However, it gets decent pressure and could also function as an irrigation syringe, making it multipurpose anyways. It's as light as the filter. The bag packs down well, but it's stiff and hard to fill up, even under a tap. Bring a ziplock to help fill it up in standing water sources.
4. Preliminary Testing - We bought these for a trip to Central America we are taking in a month, but also we wilderness guide here in Canada. In my first test I used our tap water and some neon purple food coloring belonging to our roommate. I filled the squeeze bag, added about 3 drops food coloring - enough that you could see it was purple water when you held the bag to a light, as it is somewhat opaque. The water will dribble out and it doesn't require a pile of pressure to feed it through. I probably used about as much pressure as an easy handshake and emptied the bag in less than a minute. Don't use too much pressure - the few directions on the packaging warns you could burst the bag, or damage the gaskets. What was interesting is that the water on the other end initially came out clear until you got enough of it to realize that it was actually coming out blue. What this says to me is that it filtered out the red color particles, but left the blue (it means that the red particles are larger than 0.1 micron, and the blue are small enough to get through, consistent with the product advertising, really). There were no visible floating particles in the water, to the naked eye under bright light.
Overall, I'm pretty stoked about this device. It's small, and it's obviously filtering on some microscopic level. I have no other quality filters to compare it to at the moment, but I'm satisfied that something is definitely happening through the filtration process. I'm looking forward to hooking this up to a water bladder and testing it further.
Keep in mind that this is a filter - it gets rid of larger particles in water, bacteria and protozoa. It MAY NOT be effective against VIRUSES (sorry about the caps) like Hep A, Norwalk Virus, etc. Viruses are significantly smaller than 0.1 microns and that means your water could require additional treatment to make it safe. This is not the be all, end all of water purification. It is a good start, but when in doubt, combine it with additional treatments that are effective against viruses. Generally, this means some sort of chemical addition to the water (iodine, chlorine, etc).
I may give an update after more testing and after the trip to Central America letting everyone know how it has held up. Currently not sure of how universal it is on other water bottles (definitely wont fit my glass water bottle, but I could use the straw).
Thanks for reading!
It totally removes 'water anxiety' when I'm out hiking or camping, because I know I can safely drink from almost any moving water source.
The Sawyer bags are the weak point, I've punctured two now and plan to upgrade to Evernew bags. Platypus bags don't seem to seal up against the filter properly.
I also made an end cap by chopping up a pop bottle and gluing the lid over the open neck. This then screws into the 'dirty end' and prevents any water leakage contaminating the clean end. (See Photos)
I use the Sawyer mini in conjunction with a Camelbak activated carbon filter for extra piece of mind and better flavour
If you wild camp, or spend time out in 'the wilds' it makes sense to have one of these in your pack along with your first aid kit and survival bag/bothy.
Just don't let it freeze if it's wet, or it will become completely ineffective, although you wont know until you get sick.
