About Sawyer
Since 1984, Sawyer Products has offered one of 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 Products Mini Water Filter
A lifetime of water at hand
The Mini Water Filter is the lightest and most versatile personal filtration system from Sawyer. It weighs 2 ounces and fits in the palm of your hand. While incredibly small and convenient, this filter was tested to 10 million parts of bacteria and one million parts of protozoa without a single breakthrough — the highest testing level for filtration.
The size, convenience, and performance of the Sawyer Mini filter make it perfect for everything from camping with the kids to travelling abroad where tap and bottle water cannot be trusted. It comes with all the accessories you need to use this system in any of the following ways:
Attach to the included 16 ounce reusable squeeze pouch to drink directly from the filter or squeeze water into a water bottle Attach to most disposable water or soda bottles Attach inline on a hydration pack — no adapters required Use the included personal drinking straw and drink directly from the source or scoop up a bottle of water directly from any freshwater lake, river or stream.
Drink using the included pouch
Attach to standard water bottles
Sip directly with the included straw
Filter into a water bottle
Attach inline to a hydration pack
Absolute Micron Filtering Technology Makes The Difference
The proprietary element of Sawyer’s water filters is comprised of tiny “U” shaped micro-tubes that allow water to enter into their core through tiny micro-pores. The high number of those tiny tubes and their surface area allows the filter to have one of the fastest flow rates in the world. This high flow rate eliminates the need to store water, reducing the possibility of water contamination after the filtration process.
Each filter is certified for absolute microns; that means there is no pore size larger than 0.1 in size. This makes it nearly impossible for harmful bacteria, protozoa, or cysts like E. coli, Giardia, Vibrio cholerae, and Salmonella typhi (which cause Cholera and Typhoid) to pass through the Sawyer Mini filter. Sawyer filters have been tested by independent and qualified research laboratories and found to remove 7 log (99.99999%) of bacteria and 6 log (99.9999%) of protozoa, exceeding US EPA standards. The filter does not remove chemicals, dissolved solids, or viruses. However, viruses are very rarely found in North America or when travelling to foreign cities.
Sawyer’s revolutionary filter technology is in use by hundreds of groups, including non-profit organizations, relief agencies, and governments in more than 70 countries around the world.
Frequently Asked Questions
Package Contents Sawyer Mini water filter with tip cap 16-ounce reusable squeeze pouch 7-inch drinking straw Cleaning plunger (syringe)
How will I know when the filter is full of sediment?
The flow of water will slow down. However, it will never fail. Once the filter starts to slow down simply backwash it and it will be as good as new.
Is this good for kids at camp?
Yes! It is easy and safe. It’s small, lightweight, and priced so that everyone can have their own filter. It doesn’t need all the small parts and accessories of first-generation filters to move from a hydration pack to a bottle to a pouch.
Can I put the filter inline on my hydration pack?
Yes, connectors for your hydration pack hose are built into the filter.
Can I put the filter on a different / smaller bottle?
As long as the bottle has a “standard” thread you can. Most soda and disposable water bottles made worldwide use this thread.
How often should I clean the filter?
For longer filter life, you should backwash and sanitize the filter after every outing.
If I backwash it, will the bacteria in the city water grow in the filter?
Sawyer recommends sanitizing the filter before storing it. If you backwash the filter and then use it, bacteria from the city water will not grow.
Is it going to get clogged while I’m out on a trip?
Even with very high particulate /turbid water you should get 5 to 10 gallons through the filter. If this is not enough water for your trip you should plan on field backwashing your filter.

Customers say
Customers find the water purification system fantastic at what it does, particularly appreciating its effectiveness in keeping them healthy while camping and hiking. The compact design allows it to fit in packs and attach to bottles, while being lightweight and easy to use with clear instructions. The filter works well, producing clean water from various sources including ponds, though opinions on flow rate are mixed, with some finding it good while others note it’s very slow.

Excellent, small, light and works well : ideal for travel
Excellent, small, light and works well : ideal for travel.The tube itself is small and very easy to use with Clear instructions printed upon it;(basically pull water through one end, and draw out of the other, as marked with arrows).Supplied with an extension straw for drinking and a syringe for purge cleaning.The filter itself also has a standard thread so can be attached to (any standard) water bottle.The flat pack bag, supplied, takes no space at all, and is reusable; the neck of the bag is also designed to screw onto the filter. Its a good size to carry when both both full and empty.This can do a considerable amount of water filtration, so it’s a tremendous SAVING both financially and to the environment from the scourge of plastic water bottles waste.See the Sawyer web site for the technical details, but this is a high specification purification system.Would HIGHLY recommend it is small easy to carry size and use.

Excellent bit of kit – Beware if tempted to use other manufacturer’s bottles with it.
The Sawyer Mini is an excellent bit of kit for those occasions where one cannot carry enough drinking water, and where weight carried is a prime consideration. There’s not a lot that can be added to Sawyer’s technical overview of the unit, suffice to say, provided that it is used correctly, it works. – Competently, and with a minimum of fuss!A couple of points worth noting are: -1) Some reviewers suggest that Sawyer’s collapsible water bags are very difficult to fill, unless there is a strong flow of water. The simple way to ensure that the bottle fills easily, regardless of whether there is strong water flow or not, is to “inflate” the bottle before presenting it to the water supply – by blowing into it as if you were blowing up a balloon.Of course this advice comes with the caveat that your mouth will come into contact with the bottle’s outlet, which may carry contamination from previous fillings with unfiltered water. Only the user in the particular circumstance involved can decide whether there might be any riskinvolved.2) It has been suggested that the threads of the Sawyer filter are the same as those of other makes of collapsible bottle such as Platypus,and of various plastic drink bottles.I cannot comment on the use of plastic drink bottles, but I can say definitively, that the threads of Platypus collapsible bottles are NOT exactly the same as those of the Sawyer Mini.Although a Platypus will actually screw onto the Sawyer, it will only do so with a very slight “cross threading”. In the case of the Platypus bottles I’ve tried, this resulted in a slight seepage of water from around the unfiltered “neck” side of the Sawyer. Meaning that unfiltered watercould easily end up in whatever filtered water container was being used at the time. The seepage increases when squeezing the Platypus in order to speed up liquid flow through the filter.Personally I’ve not had any real problems in using Sawyer’s own bottles, although I find the 32oz. is much to be preferred over the 16oz.The one small gripe I do have, and the distinct advantage a Platypus bottle would have, (assuming a perfect connection to the Sawyer could be made), is that the Platypus range includes a fully transparent bottle, so its content can be seen and inspected for any obvious debris or other matter. It also makes it easy to see whether the inside of the bottle has been properly cleaned and dried before long term storage.EDIT (27 May 2016)One reviewer has given a one star rating which, on the basis of his comments, I think is inappropriate.I have made a comment on that particular review, but copy that comment here, as I think it has some general relevance: -The Sawyer Mini is designed to filter out bacteria and protozoa. It is not designed for, and will not, remove dissolved solids, (which consist of minerals, salts, metals, cations, and anions dissolved in the water), Neither will it filter out chemicals in general, nor any associated tastes or smells.Totally pure water is virtually electrically non-conductive, whereas any “non-pure” water will have some measureable degree of electrical conductivity. TDS meters use this conductivity in order to display the amount of dissolved solids present in the sample being tested.Since dissolved solids won’t be filtered out by the Sawyer Mini, it is unsurprising that filtered/non-filtered TDS meter results would be the same. To give the product a one star rating based on an assumption that it should be doing something it was never designed for, is, in my opinion, not justifiable.There is plenty of information on the Mini’s technical specification, along with numerous FAQ’s as well, on the Sawyer website. Elsewhere, there is plenty of online information to be found on Total Dissolved Solids in drinking water.Reverse Osmosis, Activated Carbon type filters, Deionisation, and Distillation, are all options that will remove some, but not necessarily all, dissolved solids.

Perfect for a day or multi day hike!
I have considered buying this filter for over a year. Having recently treated myself I have certainly not been disappointed.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.

These are a must for my rucksack for hiking and camping. I also keep one in my vehicle and or my motorcycle while traveling. It’s never a bad thing to have access to tools that produce clean and safe to drink water. Simple to use and gives you piece of mind while crossing paths with questionable water.

Loved them.Used the squeeze pouch while on the trail and bought the 2 Gallon bag to use at our basecamp. Filtered lakewater in the backcountry during a 6 day trip, no issues. Simply use the plunger that’s provided to backflush the filter(s) when the flow slows to a drip instead of a steady stream.

What a great little product, small lie weight and practical, that’s what you want any day of the week on the trail. The only downside is, I found the squeeze bag (16 oz) a little too small for my liking, constantly need to fill up and filter. A large squeezy bag would be ideal.

Wir haben viele YouTube Videos geschaut um das richtige für uns zu kaufen.Die Literzahl der Benutzungszeit und das Preis Leistungsverhältnis hat uns überzeugt.Aber Achtung er filtert natürlich weniger als der Kohlefilter heraus.Bitte nicht überstürzt am nächst liegenden Bach benutzen, das Wasser darf nicht vom Menschen verunreinigt sein.
