  • +Does the Sawyer filter remove taste, chemicals and heavy metals from water?


    The Sawyer filter removes taste that comes from bacteria, dirt, and green matter.


    The Sawyer filter does NOT remove iron, sulfur, other chemicals, or simple compounds. Taste can be masked by using flavor additives like Gatorade or crystal light (filter needs to be cleaned immediately after using them).

    Heavy Metals

    The Sawyer filters are not made with charcoal. While other portable filters have charcoal, they lack in amount of media and adequate dwell time. Therefore, they only remove small amounts of heavy metals, pesticides, etc. (when used in real life applications). Try using better sources of water, if possible.

  • +Do you have more information about Sawyer’s Label Claim and Million Gallon Guarantee?

    We have independent lab tests using EPA protocols and information about our Million Gallon Guarantee that are available on our Downloads Page.

    If you are looking for a filter you will be using for yourself, the following products will be best for you needs.

    The Sawyer Mini Water Filtration System is our newest and most popular filter. The Mini weighs just 2 ounces and filters up to 100,000 gallons!  You can drink directly from the Mini, attach it to Sawyer Squeeze Pouches, use inline on a hydration pack, or attach it to the top of almost any bottled water? How about that for versatility? And like all Sawyer Filters; they are backflushable almost indefinitely. That means no expensive cartridges to replace, ever. (SP128, SP124)

    The Sawyer Squeeze Filter - This is the simple, portable, lightweight system that won Backpacker Magazine’s Editor’s choice in 2012. The threaded filter is also very versatile and also comes with a Million Gallon Guarantee. It is perfect for backpackers who want clean water fast without adding much weight.  (SP129, SP131)

    Personal Water Filtration Bottle – This is a simple bottle system that comes with a back-flushing syringe. Perfect for traveling to areas where you do not trust the water. (SP140, SP141, SP142)

  • +Filter Compatibility

    The Sawyer Squeeze Filter can be used in conjunction with a hydration pack. Please see video Sawyer Squeeze with Hydration Pack using Inline Adapter and Sawyer Squeeze with Fast Fill Adapters.

    The Sawyer Squeeze Filter with Water Bottles

    The Sawyer Squeeze Filter can also be used on water bottles when you are unsure whether or not it is safe to drink the water.

    The Sawyer Inline Filter

    This convenient filter can be used as an inline filter on a hydration pack, a pre-filter for an existing pump system, with the provided faucet adapter, or with a gravity bag.

  • +How fast should the water come out of my filter?

    Flow rates

    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. Also, the PointZEROTWO™ filter flows much slower that the Point ONE.

  • +How do I care for my filter during freezing weather?

    Before initial wetting

    Filter is safe from freezing temperatures if it has never been wetted.

    After initial wetting

    While there is no definitive way to tell if a filter has been damaged due to freezing, Sawyer recommends replacing your filter if you suspect that it has been frozen.

    During trips

    If you are in freezing temperatures, we recommend that you store your filter in your pocket or close to your person so that your body heat can prevent freezing. THERE IS NO WARRANTY FOR A FROZEN FILTER.

Water Filtration Done Right

Sawyer 2 Liter Complete Water Treatment System

Sawyer 2 Liter Water Filtration System is rated 3.125 out of 5 by 8.
Rated 5 out of 5 by from Great This item is at the top of my list for all the equipment I have. It's super reliable. It works pretty fast. It's easy to set up and do. When I arrive at camp, we find water FIRST. And fill all of our bottles from the system right at the creek, then we fill the clean bag and the grey bag and bring them back to camp. After filling the grey bag, I can go set up my tent or collect firewood,while it filters 2 liters of water (about 5 minutes), and when I come back it's all done and ready to go. Four liters of water is plenty to make dinner and drink for an entire night, and then wake up and make breakfast for a large group of people.

Rated 2 out of 5 by from Why Does Hose Pull Out? This is a great water filter system when you're going to need more than 3 liters for your outing. But why does the hose from the blue bag pull out easily and on its own. The first time out was a day pack, and I chose to use my blue bag for hydration. After about 2 miles, my back was getting cooler and then felt wet. I was so irritated to find a couple inches of water at the bottom of my pack. When I got home I tried to secure it tighter with a zip-tie, but it didn't hold with great confidence. Later, I read reviews on REI, and found this had occurred with others. WHY?!? This i a great, easy system, and the only reason I give it 2 stars. It should get 5, but not when you can not rely on it "holding" your water. I did follow someone's advice and wrapped the tube joint with duct tape. Great, that adds weight and extra work when I get home. And for my investment, I don't appreciate having to duct-tape a new product! It's hard to recommend it until THIS is corrected. *Note: We had a nice running stream and I collected several 1L bags of water for camp and others. Filtered wonderfully. Just fix this hose isssue!

Rated 4 out of 5 by from Love the concept I recently purchased the Sawyer 2 Liter Water Filtration System and I love the concept and I am sure that it works great as I have other of their products. Two things to consider when you purchase this product: It will not fit into standard Camelbak or Source hydration carriers. The mouth is wider than these products, so unless you want to cut the opening wider these will not properly fit unless you want to have a gaping hole in your carrier, with will work in a pinch, but is unsightly. This was a disappointment for me because I really like the hydration carriers that I already have, now I have to find a carrier that will work with these, but I do have packs that they will work in. Secondly, there is no kind of bite valve on the business end of the hydration hose. I am not sure why the marketing department found it necessary to have overlooked or neglected this, especially when this is a very necessary part of any hydration system There is not even a fitting on the business end of the blue hose in order to attach some kind of bite valve onto it. So if you purchase this remember that the system is not ready to use right out of the box. This is disappointing given the price tag. Can Sawyer rectify this? Have one come with this system or at least give hints as to what they might recommend? Would I recommend it: Of course, I recommend all of their products, it is just that this problem has left me scratching my head.

Rated 4 out of 5 by from Love it but 2nd year and filter won't unplug :( Bought a year ago and used it in the BWCA and loved it!!  Very easy to use and filtered at a great rate.  Brought it home, followed all the cleaning instructions I could find (which are hard to find by the way).  Went to use it this year and the filter refuses to do more than a dribble unless it is under pressure from the faucet.  Searched for solutions and came up empty handed.  Going to contact Sawyer in hopes they have an answer other than replacing the main part of the system.

Rated 3 out of 5 by from This would be the ideal setup "if" it included a bite valve and/or a way to shut water off with both bags so you could fill up blue bag and grey bag for later. Seems useless without, glad i have a good water pack, blue bag kinda useless the way it is. would have given 5 if equipped properly with everything you need with kit.

Rated 2 out of 5 by from Idea; Great. Implememtation; Not so much. I do a multi-day backpacking trip at least once a month with hikes in between, in varying regions, so having clean drinking water is a priority. I bought the Sawyer 2L bag-to-bag system with really high hopes. The overall pack weight was also very attractive. I also really liked the fact that the system could be backflushed in the field but after multiple trips the problems with the system became very apparent. The first major issue, as highlighted by other reviewers, is that the quick disconnect will remove themselves easily from the rubber grommets at the bottom of the bags. I was putting my clean water bag into my hydration pouch on my Gregory backpack, with the hose installed, and the quick disconnect fell out and started filling my backpack with my clean water. Other reviewers have covered their solutions but my solution is far more simple. Camelbak uses the same quick disconnect fitting in its Anidote series and the quick disconnect fitting is integral to the bladder. My suggestion is that if you are using the clean water bag as a hydration bladder for hiking a backpacking, purchase a 2L Camelbak Anidote Reservoir as a replacement to your Sawyer 2L clean water bag (this was my solution). The second major issue is the difficulty in filling the dirty water bag. Sawyer does recommemend that you fill the bag from a running water source (river, stream, etc.), but as all of us know, water is the backcountry comes in all forms and it is sometimes very hard to find running water. Even in a flowing stream the dirty water bag is hard to fill because the insides of the bag just stick together. Additionally, when filling from a lake you have to do a sweeping motion which can stir sediment that collects in the bottom of you bag and in your filter. The Platypus version of this product completely opens one entire end facilitating and easy fill. Since I do not want to go and buy another product because I am now invested in this one, my solution is to use my cooking pot to fill the bag instead of putting the bag in the water. I have also had to use a t-shirt twice to prevent sediment in the bottom of the bag and filter. A suggestion to Sawyer would be to install a removable screen at the opening. My friends who have the squeeze bag set-ups have the same issues with filling. The third issue is how the set-up is not provided with a mouth piece. As I said earlier in this post, the Camelbak Anidote series uses the same quick disconnect as sawyer. I went and purchased an insulated hose with an on-off valve and mouthpiece from Camelbak to fix this issue. The final issue I have found is that the tiny metal eyelet, at the top of both the clean and dirty water bags, is useless. Not a single one of my backpacks has a gear hook that can fit through the eyelet. This is a major issue because it does not keep the bladder in place and can change weight distrubution of the pack as you move. In the end, I have a Camelbak clean water reservoir, a Camelbak hydration hose, a Sawyer inline filter, Sawyer dirty water bag, and the drity water crossconnect hose. I am still trying to figure out a "full fix" soultion to my dirty wag bag issues. The filter element is great and I have no complaints about it, it is just the accessories around it that are the issue. Would I recommend THIS product to a friend? The answer is No, I would recommend that they purchase the 3-way Inline Filter or the Mini Inline filter and build their own system from the products of other manufacturers much like I have.
