Sawyer PointOne Squeeze Water Filter System

with 43 comments

Greetings Hikers!

A lot of hikers place a lot of value in making sure that their water is filtered, and rightly so. I am not going to get into that issue within this article, other than to say that there are times when I absolutely refuse to go on a hiking trip without a water purification of some sort. Because of where I live and typically hike a water filter is not necessary – it rains so much that I can just gather water by setting down my water bottle and it fills up in a few minutes. At night, if I know the next morning I will be wanting to take a quick towel body shower, clean any gear, or just to have a nice breakfast I can easily gather three liters of water, the one liter that my primary bottle holds plus a 2 liter water bag for additional storage. Of course there are times when I am just not able to gather that much water and find a need to acquire water from another source beyond just rain falling, in these times it is typically from a river or creek.

I have gone through a lot of different water filters, like most of us have I suspect, trying to find one that works for me. Forget trying to find “that perfect one”… these days I just try to find one that makes me happy and feel safe and does not weigh a lot.

I have bought the Sawyer Three-way filter but it was way bigger than what I expected it to be and thus it never made it into my backpack, plus I almost never drink directly from a storage bag and I am just not a fan of the whole gravity system. Nothing against those methods, I just do not care to go down those roads, done them both and just do not like either of them.

I have bought the SteriPen Adventurer Opti and really do love it. It has never failed me, something I hear happens to people here and there. It is also something that I do not have to worry about freezing in sub freezing conditions. If you have ever woken up and realized that your standard membrane filter is frozen and totally unusable, you know what I mean. Yes it requires batteries, but I do not care about that. It is really no different from carrying fuel for your stove, its just a necessary part of your overall total backpack weight.

Awhile back Sawyer released their “Sawyer PointOne Squeeze Water Filter System” which at first I neglected to take a close look at, but here a few weeks ago I came across it again and took a serious look at its technical specs and it jumped out at me as something that could be the finest – and lightest weight – membrane filter system available for hikers.

Technical Specs:

Filter Weight: 63.25 grams / 2.231 ounces (filter by itself without cap nor blue instructions label)

Cap Weight: 5.78 grams / 0.204 ounces (would be completely unnecessary if all you plan to do is filter water and than store the filter in a bag)

Filter Weight After Use: 82.26 grams / 2.90 ounces (filter by itself without cap nor blue instructions label, shaken and blown out as best as I can)

 

Filter Time:

It takes me exactly 1 minute and 10 seconds to filter a full 2 liter bag.

This is without the white bottle cap on the outlet. With the white bottle cap on the filter it takes me 1 minute and 50 seconds. As I do not carry the white bottle cap it does not make any difference to me. But still, under two minutes to treat two liters of water, that is pretty much untouchable by any other method out there.

Compare this to the SteriPen Adventurer Opti which takes takes three minutes to filter 2 liters of water.

Compare that to hours and hours for tablets and liquid chemicals. Read a great discussion talking about these two types of treatments.

 

How I Use It:

I typically carry no more than three liters of water, however some times a forth liter of water just becomes necessary. That is maximum water carried. Realistically I tend to carry one liter of water, whatever my bottle holds. Again this is due to living in a wet/raining environment. Your situations may be different of course.

So for me what I have started to do is to carry my standard one liter bottle and than carry the 2 liter Sawyer bag and the Sawyer Squeeze Filter.

The total weight for the filter and the bag are 92.77 grams / 3.27 ounces.

My SteriPen Opti Adventure is exactly 100 grams / 3.52 ounces.

So by switching over to the Sawyer PointOne Squeeze Water Filter System I am able to save 7.23 grams / 0.255 ounces when the unit is fully dry. Not a whole lot of weight for a UL hiker but a worth wild amount for any SUL/XUL hikers to consider.

Now I am fully aware that the ‘Aquamira Frontier Pro’ is much lighter than this at 57 grams / 2.0 ounces. However – and this is a big however – it only filters down to 3 micron. The CDC confirms that in order to properly filter Cryptosporidium, Giardia (the two biggest issues we face as hikers) you must have a filter that can do at least 1.0 Micron Absolute. Therefore the Aquamira Frontier Pro is realistically not even a viable single-treatment option for hikers.

I also want to point out here that I absolutely refuse to use pills, tablets, or liquids chemicals to treat my water (baring the use of bleach in very rare situations). The whole idea of having to weight hours and hours for me to be able to drink water is just idiotical. Many of the popular tablets out there today require you to wait hours before you can safely drink the water. Take for example the ‘Katadyn Micropur’, it requires a wait time of at least 4 hours in cold temperatures! I am sorry folks, but if all of a sudden I realize that I am suffering from water deprivation, or end up drinking a lot more water than I expected because of a tough hill climb, the last thing I need for my well being, my safety, is to have to wait potentially a number of hours before I can safely drink the water I have been lugging around – I do not care how you look at it, 100% dependence upon tablets, pills or chemicals is not safe. (just as 100% dependance upon a membrane filter is just not safe – always have a redundant system in place, for me, its bleach, which I am already carrying)

 

Bag Durability:

(update: Please see my article entitled “Sawyer Squeeze – Updated 2013” for further reading on bag durability and a new version of the bags.)

There is a lot of talk on the internet about how durable the bags themselves will be – and rightly so. Given that the idea of this whole system is that you have to actually squeeze and crunch and abuse the bags, hopefully Sawyer had the foresight to actually make them tough enough to handle a thru-hike.

Given the fact that you can buy three of the 2 liter bags for around $10 bucks, whereas a 2 liter platy bag usually costs around $12 bucks for one, if the bags are just as durable that will be very sweet, as they would thus be both less expensive and lighter weight than the 2 liter platy, which has become a mainstay in nearly every backpack these days.

Should you puncture a bag and you do not have another bag, you can always screw it onto the top of most plastic bottles out there that use a standard top connector, such as a 2 liter bottle that you can pick up from just about any trail town. It also fits on a few 1 liter bottles that I have tried, but I am not going to start listing each and every freaking 1 liter bottle and whether it fits on them or not, so do your own home work on this ;)

I cannot remember exactly when they came out, but it seems like it was the end of 2011 (Octoberish?), which means that the 2012 thru-hiking crowd will be the first group of thru-hikers able to really put them through the test, so if you are out there hiking in the 2012 season I would love to have you jump back to my website after your hike and share how they work out!!

 

Playing Nice With Other Bags By Using Alternative Washers:

Following-paragraph added August 23, 2012: Ok so there has been a lot of discussion going on around the internet about getting the Sawyer Squeeze to play nice with other bags. I have spent an insane amount of time (and a fair bit of money) buying different water bags on the market, and different size washers, and connectors, to see what it will take to get the Sawyer Squeeze to work with other bags without any problem. My conclusion at this point in time is that it is just not worth the trouble. I can get different washers to make it work with some bags, but not other bags. Same with different connectors. In the end what I have ended up doing is switching over to the Evernew Water bags (available at places such as Gossamer Gear) which fit perfectly onto the Sawyer Squeeze without any modifications to the Sawyer Squeeze. I also find the Evernew water bags to be much nicer than the Platy 1-liter soft bottles (the cap is bigger and easier to open on the Evernew bags) so my advice is to just throw away the Sawyer Bags (or put them in a WTSHTF bag/box) and go buy yourself some of the Evernew water bags and just be done and over with it. (end of additional paragraph)

One of the key issues facing all of us as hikers these days is that there are only a small handful of water bag containers out there – Platyus, Camelbak, and Hydrapak being the big three. So we would expect that when a water filter manufacturer releases a new product it will play nice with both of the big two companies that make water hydration bags.

For the most part the the Sawyer PointOne Squeeze Water Filter works not only on the provided Sawyer water bags, but they also work on most of the Platyus and Camelbak hydration water bags. There have been reports by some that a bag here or there does not properly seal – which is bad, as it could allow dirty water to drip down into your clean water.

The filter itself does fit onto a Platy 2 liter bag, with rare situations where it does not work, and for those situations it has been discovered that a simple garden hose washer totally solves the problem. ref

I have also been told by a hiker (Thumper) within the pct-l mailing list that Sawyer has released “a new adapter set that allows the Sawyer PointOne Squeeze Water Filter System (SP-131) to be used in-line with Camelbak by attaching the filter inline with the bladder and drinking tube inside the pack… the adapter set is SP-110 and costs $6.99 plus shipping” ref

So this will be awesome for those that like to go the route of a double bag gravity system and would like to go with this lighter weight filter rather than the heavier Three-way filter. This new adapter could (maybe?) also be used in a few different situations… such as doing a system such as hydration bag -> filter -> new adapter -> standard hose with bite-valve. It will be interesting to see if that combination could work out, and how much force it would take to pull water through the filter, I suspect it would not work all that well, but if somebody out there buys ones of these new adapters and tries this, please stop back by here and post whether or not this works!

The Sawyer bags are lighter and less expensive – if they prove to be just as durable, or even nearly as durable, it could be illogical to go with a more expensive and heavier water hydration bag.

I have tested the Sawyer PointOne Squeeze Water Filter on my 2 liter platy bag and can confirm that it does not work – the filter will not properly screw onto the bag, which kind of sucks that Sawyer was not willing to play-nice with the Platy bag.

I do not have a CamelBak hydration bag to test it on so I am unable to provide any solid and reliable personal details on how the two play nice with each other.

I received an email yesterday from a hiker by the trailname of “SomeGuy” who after reading this article he went to a local big-box-store and purchased both a 1/16th washer (think a washer for your garden hose) and while he was there he also picked up a couple of these to try. This second one could sort of be kind of neat if you are going to be somewhere that there will be a lot of small sticks and mud chunks and other debris in your dirty water source.

I myself have swapped out the original washer for a 1/16th and can confirm that it works perfectly on both the 2l platy bag and the original Sawyer bags. So for $0.49 cents, just go buy one of the 1/16th washers and throw it in there (replacing the original), as than should you find yourself needing to use a platy you will not have to wonder if it is going to work or not.

 

Alternatives To Bags:

There are a few alternatives to using bags for those that have issues with the Sawyer bags, or just using bags in general.

One solution so far has been from Ed “Eeyore” Jarrett where you take a water bottle and cut off part of it and attach the top part of water bottle to the dirty water part of your filter. See the photo for an example. He goes into detail within his own review of the Squeeze which is a great right up and worthy of a few minutes of your time.

As he states, “But if you have a soda bottle top for a scoop like I do, you can screw the top onto the input side of the filter and then use it as a gravity filter.  My scoop is about 4 inches long and, so long as I keep it nearly full, will allow me to fill a quarter Gatorade bottle in about 7 1/2 minutes.  That is slow, but easy, and does give you a fall back without having to carry an extra bag.

Seven minutes to filter a one liter bottle is a lot longer than the 2 minutes it takes to filter a two liter bag, but such is life sometimes on the trail, eh!

Another option is that Sawyer has released SP110 which are inline adapters that attach to both ends of the Squeeze and allow you to connect directly to water drinking tubes, or gravity feed bags. These work very good and I have used this method myself. You can buy them at: Sawyer, GossamerGear,  Amazon, REI, and elsewhere. I think this works great in a gravity system, but I found trying to drink water through the filter via hydration bags to be too difficult for my likings.

Backflushing:

I have had a few people message me about backflushing/backwashing this filter and if that crazy huge and heavy syringe is something all of us are going to have to lug around.

I had to go on a hunt to find some exact figures on how often Sawyer recommends you backwash this filter and they recommend doing so every 5 through 10 gallons of water. Many thru-hikers consider the 8 liter mark the mark to shoot for when it comes to water consumption per day (especially in desert regions) so that means that every 4 or 5 days you should consider backwashing it. That is perfect for those who use a bounce box from town to town. If you are not up for using a bounce box and want to carry the syringe, I just threw it onto my scale and the syringe is 33.34 grams (1.176 ounces). Another idea that would be slightly heavier by 0.2 ounces, but that take up waaay less room inside of your backpack would be one of those “Tornado Tubes(amazon affiliate link) then you could just throw a bottle of water onto the outflow section and backwash it with a normal plastic bottle of water. I really liked this idea but I was unable to find any tornado tube that fit properly, others have found ones that work, but I have not been lucky enough to.

Freezing Temperatures:

There has been a LOT of discussions and arguments about whether or not the Sawyer Squeeze can survive freezing temperatures. I have long held with the fact that any freezing of the filter should result in you throwing away your filter. I have zero evidence to prove such a drastic action, but to me the facts are simple: the squeeze is a Hollow Fiber Membrane filter. What this means is that there are a whole bunch of very very small tubes inside of the filter (read more on wikipedia regarding membrane filtering) and this is really good in that it allows for significant amount of more water<->surface contact thereby allowing the water a higher chance of being filtered. But the downside to this is that the tubes are significantly smaller than non hollow fiber membrane filters, like most other backpacking water filters. These smaller tubes mean that any water trapped inside of them results in a drastically higher chance of that water freezing and as we all know, when water freezes it expands in size, and therein is the problem. When the water freezes it a very high likelihood of blowing a hole (rupturing) one of these very small tubes. When that happens it means there is a very high chance of allowing water through the filter without being filtered.

Here is the official position of Sawyer via their FAQ page:

While we have no proof that freezing will harm the filter, we do not have enough proof to say it will not harm the filter, therefore we must say that if you suspect the filter has been frozen, to replace it — this is especially true with a hard freeze.

Only you can decide if the risk is worth it, personally, I do not. Puking my guts out four 2-4 days, than being constipated for 4-7 days is simply not worth it to me. $50 bucks is not worth a week or two of suffering.

Videos:

This is the official promo video for the filter. It does not really highlight anything special for this filter, but I felt like I should include it within this article.

In this second video by you will see a nice way to solve one of the problems with this filter – personally I do not find it necessary as you can easily shake it out and blow it out good enough to put into your backpack – but it is a neat idea, specifically bounce ahead to the 7 minute 50 second mark.

http://www.youtube.com/watch?v=nw6cCAXn1_g#t=07m50s

 

In this third video you can see how much water you could put through this filter before it would need to be replaced – theoretically. Bounce head to the 9 minute mark. I laughed pretty hard when I saw this part of the video. Beyond amazing!! (adult notice: bad language)

Replacement Bags:

Update: April 18, 2013 – Mountain Laurel Designs has gotten access to, and has started to sell, multi-packs of the new Sawyer Bags in both 1L and 2L sizes! They are $15 bucks for three 1L bags, and $15 bucks for two 2L bags. They are a 9-ply bag, compared to a 5-ply bag of the Evernew bags, and they are estimated to be 4 grams less weight than the Evernew bags.

 

Final Thoughts:

Until something lighter comes along that provides full 0.10 Micron Absolute level filter that does not involve waiting hours and hours to have drinkable water, and is under the 2 ounce mark, the Sawyer PointOne Squeeze Water Filter System is going to be the only filter making it into my backpack. It is fast enough for my needs, is light enough to justify carrying in those situations where I know I will need a filter, and while it is a bit expensive, it is far cheaper than a UV filtering system and far less expensive than buying the other filters out there that do not have a total gallons rating that this does. Every way I look at it, this is the winner in every category when it comes to a water filter for hikers.

  1. I guess my thing with it is, everyone is making this big deal about how this is the coolest thing since the first guy to swing a pack on his back and I’m still trying to figure out how is it any different than a Aquamira Frontier Pro?

    • Thanks for the comment. I addressed that issue you have within the ‘How I Use It’ section. This issue is a huge difference – or rather, a very very small difference.

      • Thanks! I went back over that section and I think I’m with you. I HATE putting tabs in my water and with my family history of hypothyroidism it can actually be harmful with the iodine tabs. Somehow despite everything out there the micron comparison is something that had escaped me. Now I’m looking seriously at grabbing one of these for my next trip!

  2. Great filter, I am just wondering how it will work for my family outtings. I like to bring a large amount of water back 4L. to share with 4 people.

    • Hey Matt,

      I have not had a chance to take it on a group hike yet, but first chance I do I will be taking it. I usually only go on one or two group hikes a year (much prefer solo hiking) so it will probably be awhile before I get a chance to use it in that kind of a setting.

      Sawyer sells the bags just by themselves and I picked up a secondary 2 liter bag that I will carry with me on my long distance hikes. That will give me a total of 5 liters of water I could carry. And, I suppose I could always use my pee bottle if I needed an extra 6th liter of water – the filter would take care of any issues with using it.

      I am not sure what would be involved in turning this filter into a gravity filter.. that could take a couple of trips to different hardware stores to device up the right parts. The Sawyer Three way is a far better filter for a gravity filtering system.

  3. Great review John.

    I am in the chemical group…but I won’t go there…to each his own huh? :)

    However, I would like to have a light weight, independent filter that I feel that I could rely on, and that won’t weigh my pack down (I have worked hard to get it light(er) and not looking to heavy it back up!). As you probably know, I too had the 3-way filter a little while back, and the I had the same feelings as you…it never made it into my pack…instead it went right back to the store that I bought it from (gotta love REI). My issue was mainly the weight…It was heavier than advertised when dry, and then much heavier when wet, which is the weight that needs to be considered when hiking. The dry weight is for when it is sitting at home on the shelf…then who cares how much it weighs…

    When Trent put out his video (the same one as above) I was really interested…but at the time not looking to drop more $$ on another filter. But it looks like it will be a nice alternative to using my chemicals…so I figure that one day sometime in the future I will give this one a try.

    Anyway, thanks for the report, and the weights! It is nice to get verification from an actual person and not a box!

    • Hey Stick,

      Yeah, I was thinking of you when I was writing about the chemicals :-p

      I know what I said about chemicals / tablets is gonna get me in trouble with a lot of people, but I am going to stand by my statements – from a medical perspective.

      Yep that three-way was just insanely huge. I still have it in a box around here somewhere. Probably never ever going to use it, I should just sell the thing for those who are into gravity filters or those who do not care about the extra three or so ounces.

      I had not seen Trents video until after I published this article. He messaged me and told me about it – glad he did as the point he makes about the life-time of use of the filter really really puts things into perspective, and makes the Aquamira Frontier Pro into something even less desirable to me as a long distance hiker.

      I hear ya on the whole issue of true weights verses advertised weights. Next to tent manufactures, these companies in the water filter world seem to be a pretty close second to not advertising true weights.

      Thanks for stopping by and taking the time to comment!

      Freaking love your website!! I have been reading it for awhile now!! (though you love that nasty white snow stuff a lot more than I do :-p)

      Awesome to hear you are going to pick up one!! The smallest size bag (16oz) could be really awesome for trail running. Its pretty small and at 18 grams I doubt there is anything else out there at that weight.

      Thanks for stopping by and taking the time to comment!!

  5. John, Thanks for the review.
    Could you clarify something please? You state:

    “The CDC confirms that in order to properly filter Cryptosporidium, Giardia (the two biggest issues we face as hikers) you must have a filter that can do at least 0.10 Micron Absolute. Therefore the Aquamira Frontier Pro is realistically not even a viable option for hikers.”

    However when I go to the CDC link you provided it states:

    “Filtration has a high effectiveness in removing Cryptosporidium when using an absolute less than or equal to 1 micron filter”,
    and,
    “Filtration has a high effectiveness in removing Giardia when using an absolute less than or equal to 1 micron filter ”

    Are your figures of by a factor of 10 or am I misreading them? Thanks in advance.

    • Hello Lance, thanks for letting me know about the typos. I have changed the single incorrect instance of 0.1 to 1.0 and the single incorrect instance of 0.3 to 3.0 — to many dots and zeros floating around in the brain lol

  6. “100% dependence upon tablets, pills or chemicals is not safe.” Wow, pretty strong statement there, John. I would say the same for filters. Whereas chemicals will never fail (unless you lose them or don’t know how to use them properly), all filters, electronics, etc will fail eventually so you must carry a backup. Can you effectively backflush this without the syringe? What if it freezes? How can you VERIFY it is actually filtering properly?

    Giardia and crypto contamination is way overblown in most areas. The 4 hour wait time is only if near freezing water AND dirty AND highly contaminated (downstream of cattle, beaver, etc). For most of us this isn’t an issue and you only need to wait 30 minutes. You learn to plan your capacity accordingly. Someone of your experience shouldn’t have any problem with this.

    It will be interesting to see how well those bags hold up relative to Platypus models.

    • Hey Michael,

      Yes I agree it is a pretty strong statement. My belief is also that 100% dependence upon a membrane filter is not safe either. I always carry a micro-dropper of bleach that goes inside of a large ziplock bag. I primary use this bag/bleach for washing my socks/briefs whenever I am able to spare the extra liter of water. The bleach also allows me the ability to properly treat water should the membrane filter freeze at night (or until I got this, should the SteriPen fail on me, which it never did). Any complete dependence on one specific method is just not safe if you really expect to have to be filtering water. I figured I did not need to state such a disclaimer, giving that the vast majority of the readers of this website are UL/SUL/XUL hiker who already have a head on their shoulder when it comes to hiking experience ;)

      >>> The 4 hour wait time is only if near freezing water AND dirty AND highly contaminated (downstream of cattle, beaver, etc). For most of us this isn’t an issue…

      lol, see that is exactly the problem for me. The few times I have found it necessary to treat water is exactly because of those reasons. We have free grazing cows all over the backwood where I typically hike. And while not as large of a threat, we also have bears, elk, and massive Salmon and Stealhead die offs after each spawn. But for me, it is usually the stupid cow or if I am on a trail where a lot of people with horses have been riding through.

      >>> It will be interesting to see how well those bags hold up relative to Platypus models

      I agree. Given that they are 9 bucks for three of them, verses 12-15 bucks for a single Platy 2 liter, and given the fact that they are called “squeeze” and *hopefully* the company releases we have to actually squeeze and crunch and abuse the bags… hopefully… they had the foresight to actually make them tough enough to handle a thru-hike. I have not heard of anybody actually putting them to the test on a thru-hike yet.

      The filter itself does fit onto a Platy 2 liter bag, with rare situations where it does not work, and for those situations it has been discovered that a simple garden hose washer totally solves the problem. ref

      Thanks for stopping by and taking the time to share your thoughts!!

      • I use bleach also but know that unlike chlorine dioxide it is NOT effective against cysts.

        Hopefully those bags prove themselves. I was looking into a Platy for extra capacity, but if these are that much cheaper (and lighter!) I think I’ll go this route.

        Michael

        March 7, 2012 at 11:43 am

  7. John,

    Would the pre-filter and quick connect fittings from an Aquamira Frontier Pro work with the Sawyer as in-line adaptors?

    The pre-filter fitting is 28mm male x 28mm female. The male end houses the pre-filter element and the female end has a male hose nipple in the center. This should be all that’s needed for placing the Sawyer in-line with a hydration system. The separate universal quick connect is 28mm male x male universal quick connect and is another option.

    Thanks in advance, Lance.

    • Hey Lance,

      I will have to say up-front that I have no knowledge of the AFP system. The first time I saw it I looked up its specs and as soon as I saw it say it was 3-micron I stopped looking at it.

      I just hunted down a video that showed the filter connector, so at least I have an understanding of what it is you are talking about, but I have no idea if it would fit or not.

      Sawyer has still not released any formal details on the SP-110 connector which should do the same thing. Though I have been told you can call them and they will mail out one to you.

  8. [...] Review by John Abela from HikeLlighter.Com [...]

  9. I enjoyed reading about your experience- I have always fallen back on a heavy MSR filter primarily because it was easy to operate and clean, but at one pound seems like overkill. I was wondering if you ever had the chance to test the tornado tube backflushing idea. I loved the idea, wonder if it worked!

    • The little tornado tube I bought did not fit onto the filter. It does fit onto the platty bag but not the sawyer filter head which is smaller than the tornado threads.

  10. FYI I found a lite and effective way to seal the input end of the Sawyer filter by cutting off the top of a soda bottle and then gluing in place into the opening an internal pipe thread protector which fits perfect in the soda top, weight 2 grams. I also experimented with a way to back flush the filter by bonding two soda tops together and drilling a hole in between then use the clean water in the Sawyer bag to back flush. The bonding method I used was to place one cap on a lathe and spin it at 1800 rpm and then place a stationary top against the spinning top to melt the two together, weight about 2 grams. I know not to many people have lathes so maybe a 2 liter Tornado top would be good to.

  12. Hi John, just finished reading your review, as usual it’s very thorough. I’ve always been an AquaMira user and completely satisfied. After a recent intestinal problem (unrelated to water treatment) it’s apparent that I’m going to have to be more cautious with the water I consume from the backcountry. Based on your review and others the Sawyer PointOne Squeeze fits with my style of backpacking. If I go with the PointOne I will be using it with my Platy 2L with the washer.

    Since you published the review do you have additional info on performance and how are the bags holding up.

    thanks

    • I only take a single bag with me, and it is holding up very well. If you intend to use a platy you will have to go the route of buying a washer – which is only about 30 cents. All in all, very happy with this product. Just be aware to never let it freeze. It sucks having to remember to put it into your sleeping bag on those sub-freezing nights, but better than having the filter fail.

  13. Hi guys, Tech-Na-Bill here. I got the squeeze and love it. I also carry the Adventurer SteriPen, I have used both in a cafe in Mexico on tap water and watched all the people gasp, ha, that’s fun. Anyway, I first carried the Squeeze hooked to their biggest bag for campsite use, now I have it rigged to the med bag in my pack as a blatter rig. I just pull it out to use in camp. Man, Love it. Never got sick, don’t really use my SteriPen anymore, but can’t bring myself to leave it behind. Redundancy and all. I’m at 18 lbs. with 2 lbs. of water and five days of food. I was at 38 lbs. before I started going lighter. Anyway, Hike on.

    • Hey Tech-Na-Bill, thanks for stopping by!!

      I think a lot of guys are starting to discover this fact of just what Sawyer has accomplished with this most recent product of theirs. It truly has set a whole new standard for water filtration for hikers, especially for those who are gram counters and looking for a viable non-chemical method of purification.

      Nice to hear you are in the 8 pound range for your BPW!! I spent about a year hovering around that range as I was trying different types of gear and learning my way through how different types of gear can perform multiple roles while hiking. There is just so much to learn when you are at that range. It is really the starting point for going SUL and the amount of gear education (and safety) from the 8 down to 4 pound range is insane.

      What I do with the Squeeze these days is I carry the filter and the included 1 liter bag which is a dedicated dirty-water-bag. A lot of folks have been saying the sawyer squeeze bags have reliability issues so I figured using it as a dirty-water-only bag, it should not be that big of an issue. I also made the switch away from gatorade type bottles to the somewhat new Platy 1 liter soft bottles, I carry at least two of them at all times.

      Again, thanks for stopping by and taking the time to comment!!

  14. Hey, John! Picked up a Squeeze based on your review and then spent a good deal of time trying to track down the Evernew bags. Managed to get a .6L from Trail Designs, but had to rely on the kindness of a BPL user (Doug Ide) who graciously gave me his 2L. I know you can attach the Squeeze to the 2L and then squirt it into the .6L, but I was looking for a way to connect the whole thing in series so I didn’t have to worry about spilling or keeping the two bottles aligned. Not sure how necessary that is to worry about, but I was curious. Turns out you can get a couple 3/4″ PVC hose fittings at Home Depot and couple the Squeeze to the .6L bag making a complete seal. The pieces I had to get add about 1.7 oz for about $3. Still deciding if I found a solution to a problem I didn’t really have but thought you might like to know.

    • Very sweet to hear Rick and thanks for letting me know!!

      I am pretty sure I know what the hose fittings you are talking about are. Very good idea!

      The route I ended up going with was the “Platy drink tube kit“… the one end screws on perfectly onto the Squeeze and than I just cut the tubing down to a foot or so, and than I can shove the tubing down into just about any bottle or the evernew bag to fill them up.

      October 15, 2012 at 8:50 pm

      • Do you need any kind of gasket with the Platy connection?

        Rick Burtt

        October 15, 2012 at 8:54 pm

        • hey rick, nope, it screws on there perfectly without any washer or gasket or anything. very tightly too. I just snapped a photo for you.

          I just tried attaching an entire water bladder tube with the normal bite-valve on the end of it, and than attached the squeeze to a 2l evernew bag, to see if it would be possible to suck the water from the bag and through the filter, and while it took some doing, it actually was possible. Not sure I would want to do that on-trail though.

          But anyway, yeah, I just tried two different platy drink tube kit connectors and both attached right onto the squeeze without any thread problems and with zero water drips.

    • I have seen a lot of discussions on BPL and other websites of folks talking about them attempting to dry it. As I see it, how do you really known when the inside of a hallow-fiber filter is actually dry or not?

      Think I would have to refer you to Sawyer tech support to get a solid answer on this one.

  20. [...] My Sawyer Squeeze article that I published a little over a year ago has apparently become one of the de facto articles for this product on the internet, which is really cool. It gets a lot of attention from hikers, hunters, adventurers  and travelers, from around the world. It is always fun to see an article in a language I am not even able to read (thank you google chrome for having an automatic language translator) and it is the second most popular article I have written.

  21. I’ve noticed that there is a difference in the hole size in the washer on the input side. Some are nearly completely open, while others have only a very small hole in the centre. Any idea what this is about? And should I change mine to a bigger hole?

    • Nope, no idea. I gave away my original squeeze filter to a buddy so I have nothing to compare it to with my new one. Sorry.

  22. This really is a remarkable little filter. I’ve been a long time user of AquaMira drops but I’ve taken the squeeze on my last couple trips and the utter convenience and ease of use outweigh the grams I save with the drops. I’m pretty sure the squeeze is going to be my go to method for making water potable. Great write up by the way.

  24. Hi John. Thank you for your work. What if you have need to use very dirty water (with debris; from a swamp; something like that) to purify? Thanks in advance.

    • Hey RS, like most hikers, I typically carry a towel of some sort. I personally usually carry a lightload) in or around my cook setup. Had to use it awhile back when getting water from this pretty little stream that for some reason looked really clear but was full of debris.
