  • Hollow-fiber membrane offers a high flow rate; sip on the Mini like a straw and it filters the water while it's on the way to your mouth
  • Get down close to the stream or lake and use the filter to drink straight from the source, or fill your water bottle and insert the filter to start sipping
  • Filter will also fit the threads on the included Sawyer 16 fl. oz. reusable pouch that you can fill at a lake or stream and then use to squeeze water through the filter
  • 0.1-micron filter physically removes 99.99999% of all bacteria, such as salmonella, cholera and E.coli; removes 99.9999% of all protozoa, such as Giardia and Cryptosporidium
  • Use the included syringe to backflush the filter to maintain a high flow rate
  • Filter will also fit the threads on most bottles of water that you buy at a grocery store; can also be used as an inline filter (adapters and hoses not included)
  • Avoid freezing this filter; freezing may ruin the hollow-fiber membrane
  • Includes Sawyer Mini water filter, one 16 fl. oz. reusable squeeze pouch, a filter tip cap and a cleaning syringe

Rated 5 out of 5 by from Great Depending on Use Don't expect the performance from this smaller version that you get out of the regular Sawyer. Of course the flow rate is less. If you squeeze the bag harder you will just break the bag. I use this on weekend backpacking trips where I am not on a timeline. Cause if you are in a hurry you will be angry with this one. I bought mine with some extra 64oz bags. Cause the 16oz that comes with it is too small. Set up a gravity system and eat a snack or dinner and let your water filter. There are plenty of videos on how to do it.

Rated 5 out of 5 by from Simple and Worth IT I Love the price and the weight factor. I gave up on filters for at least 15 years tired of the weight and extra hassle to get water and was back to my old iodine methods. The mini brought me back! It takes getting used to, yes the plastic pouch is hard to fill on its own as the water pressure squeezes the air out, I resorted to using my Snow Peak pot, or a small expendable water bottle to fill the pouch and then squeeze. I just used this on a 5 day adventure through the Trinity Alps and am satisfied with the system, My pouch has shown signs of use though as a clear laminate is now peeling off, however as long as it continues to hold water I don't mind. One thing to keep in mind as I hear from thru hikers is that you MUST back flush this thing regularly. I did not on this trip, but now that I am home I will consider it a part of my gear maintenance. You can't go wrong with this, great value.

Rated 4 out of 5 by from Very versatile This filter can be used as an inline, gravity, or pump filter. We actually use them in all those configurations. Screw it to the top of an empty 20 oz bottle, and you can top off at any water source. Connect it to spare water bladder without a top cap for gravity filtering while you set up camp. If you want a lot of clean water fast you just need to connect it to output hose of a siphon pump from the hardware store (5-10 dollars). The one drawback with this filter is that it has minimal effect on improving the taste of the water. In my opinion only a ceramic will get that done. I have owned the MSR Miniworks for a few years, but wanted an option that would serve for both pump and gravity. The sawyer did way better than expected, and now has a permanent place in my bag.

Rated 5 out of 5 by from Flawless Over the past 40 years, I have used iodine, PUR, MSR, Katadyn, steripen and various others and after just a few weeks with this new methedology the Sawyer system was immediately my favorite. It seems a little backward, you pack contaminated water and filter as you use. However in function there are many valuable options to this. Not the least of which, you have a reserve water suply already for boiling something. I've used it on long stretches of the pacific crest trail, in urban areas, and in refugee camps in Iraq. On the crest everyone you pass by who is making the full trek have Sawyer sips and an array of half liter water bottles. It obviously is becoming the tried and true system. I just can not speak highly enough of the Sawyer system, learn how to use it and then modify the water storage techniques as you wish to control what you pack.

Rated 5 out of 5 by from Great filter I have used a Pur Hiker for many years, and it worked ok. However, it is not the fastest pump, is pretty heavy, and replacement cartidges tend to be expensive. This little (and I emphasize little) works great. I took it on a recent trip to the Superior Hiking Trail and used it to filter water from a river, a stream with little more than a trickle, and a lake. It worked well for all three cases. The only trick to being efficient is to get the filter bag filled up. It is a heavy gauge plastic that tends to collapse flat. Getting a bit of water in it and then opening the bottom of the bag tends to make this easier. The filter is very easy to backwash using the included syringe. My only suggestion would be to purchase a larger one liter bag, as the included 1/2 liter is pretty small, especially since it is tough to get the whole bag full.

Rated 4 out of 5 by from Good choice for solo hikers I used the Sawyer filter on a section of the John Muir Trail. The weight is ideal for solo hikers who prefer filtration over options like tablets and Steripens. However, it's tedious to use. The small-mouthed, collapsible bags are very hard to fill unless you have a fast-moving stream. I'll take a solid water bottle or use a cup next time. It also gets tedious sucking through the "good" end or squeezing the bag to force out water. For a group, I prefer the Platypus Gravityworks, where its extra weight is amortized over the group, but for solo trips, I'll take the Sawyer again.

Rated 5 out of 5 by from Everyone complaining about this is doing it wrong Lightweight, efficient, better than hauling water everywhere when you know you're hiking/camping near water. Buy one of the hydrapak collapsible water bottles and the sawyer fits snugly in the top. The Hydrapak is much easier to fill than the bladder that comes with the Sawyer. Just put the rubber tube on the bottom of the filter before you insert it into the Hydrapak. It's a little tough to drink through at first but don't be a baby. You're outdoors for a reason.

Rated 5 out of 5 by from Absolutely without fault. Bought one of these, somewhat unsure about water filtration for backpacking. This little guy is AMAZING. And EVERYONE uses them! Met three people with sawyer minis on my last hike. Cut your hose on your camelback and it'll fit in line, use it to fill bottles first (like I did) and the flow rate is impressive. It takes 2-3 minutes to fill, cap, and filter 16oz, which is not bad at all. And it doesn't matter if there are bits of "stuff" in there, like purification tabs, it's lighter than a box of purification tabs, it imparts no taste into the water (lake and stream water tastes really nice, better than my home tap) and purifying it is easy as cake. I do wish that the plunger for the backwash actually screwed onto the end like it's threaded to do, but it works pretty well and you don't need to do it very often. I've done about five gallons so far and have only backwashed it for storage. Usage wise, be firm, but not TOO firm. You'll figure out how to best filter the water, just don't try to squeeze it too hard. Like I said. 1.5-2 minutes to filter the 16oz bottle. You could easily make this into a gravity system too with nothing more than a hose on each side and a container at the top and bottom. It will gravity feed, although somewhat slowly.

How difficult/involved is this to use as an inline filter with a reservoir?

Asked by: LeslieKate
All you need to do to use the Sawyer Mini Water Filter as an inline filter on your hydration reservoir, is to cut the drinking tube at the location you want the filter. The filter has an in port and an out port. Each end of your cut drinking tube will fit onto these ports, just make sure the filter is oriented with the clean end feeding out to your bite valve.

how long does it take to filter one quart with Sawyers Mini Filter

Asked by: rrrrrrrrrrrr
The Sawyer Mini Water Filter will filter a quart of water in approximately 1.5 minutes. One thing to keep in mind is that flow rates vary depending on how clean the filter is and how well you cleaned the filter. Altitude also affects the flow rates (the higher you go the slower the flow).

There are no specs as to what it filter! OK - so it makes it cleaner. Less pathogens. I want to know what micron size it filters down to and anything else that is telling me what it removes. Isn't that SLIGHTLY important?

Asked by: Curious
​The Sawyer Mini Water Filter is rated to 0.1 micron and removes 99.99999% of all bacteria, such as salmonella, cholera and E.coli and removes 99.9999% of all protozoa, such as Giardia and Cryptosporidium.

How often do you need to backwash this filter?

Asked by: deturner
You should backwash the Sawyer Mini filter when you notice that the flow has decreased. A proper backwashing can restore up to 98.5% of the filter’s flow rate.

What is the flow rate?

Asked by: Jack
On average, this filter has a flow rate of 1.7 liters per minute out of the package. This will decrease with use (especially in dirty water). When the flow rate decreases, you will need to back flush the filter.

Will the sawyer mini make tap water from South America (Bolivia and Peru) safe to drink?

Asked by: AlexDen
The Sawyer Mini will filter out most bacteria and protozoa found in water, but won't remove any viruses that can be a concern in foreign countries.
