Sawyer Sawyer Squeeze Water Filter Review 2019

Sawyer Squeeze Water Filter Overview

Are you someone who loves filtering water? If so, would you like to accompany me on my next trip? Because I hate filtering water. In fact, I would go so far as to say that nobody I’ve ever hiked with enjoys filtering water. It’s just one of those annoying tasks that needs to be done in order to survive. Unless you’re a human cactus, in which case, good for you.

The Sawyer Squeeze might be the next best thing to evolving into a human-cactus hybrid. This small, lightweight, and effective little tool completely changed my outlook on what it takes to filter water in the backcountry. No more big messy set ups weighing you down and no funky tasting tablets infusing your water with chemicals.

We’re recommending the Sawyer Squeeze as our Budget Pick for the Wilderness Backpacker because of its low price tag, ease of use, and and long lifespan.

The Sawyer Squeeze water filter has become one of the go-to basic water filters for backpacking, especially thru-hiking. You can use the included pouch or a disposable water bottle to store water, then filter straight into your mouth for clean, easy drinking water. While it can clog occasionally, and doesn’t filter well for large groups, at 3 ounces and $40, you’ll be hard pressed to find something as small and handy on the trail (unless it’s the MINI, the smaller, cheaper brother, which is best for truly ultralight backpacking.)

If you want an even cheaper filter, consider the Sawyer Mini. The Mini is essentially the Sawyer’s little sister — it’s smaller, weighs less, and doesn’t have as good a flow rate as the Squeeze. Ultralight backpackers like the Mini because of its weight, but regular backpackers will appreciate the flow rate of the Squeeze enough to make it worth the extra $15 and 1 ounce of extra weight.

Sawyer Squeeze Specifications

Feature Type Feature Specs What This Means
Weight 3 oz. (85 g) This is the weight for just the filter. The extra accessories weigh various amounts, but all are fairly lightweight. You won’t need them all during your trips.
Filter or Purifier? Filter The Sawyer Squeeze filters bacteria, protozoa, and sediment. It does not filter viruses. More on the difference between a filter and purifier in our Guide.
Treatment Type Squeeze Squeeze the bag to make water come out. This system is also ready to be rigged as a gravity filter, or for use in-line with a hydration bladder. More on treatment types in our Guide.
Effective Against Protozoa and Bacteria The two most common issues in backcountry water in the U.S. It also filters sediment.
Filter Pore Size (Microns) .1 microns This is the size of the filter, and indicates what size pathogens it stops. This is a standard micron size for filters. More on filter pore size in our guide.
Filter Media PointOne Hollow fiber membrane Hollow fiber membranes are the most common filter media for backpacking. They allow a decent flow rate and clean easily, but suffer in extreme cold. More on filter media in our Guide.
Flow Rate ~1 liter per minute When filtering from a completely clear stream for the first time, you might get closer to the advertised 1.7 liters per minute. But our tests showed less than that, clocking in at about a liter per minute. This is still solid for the size of the filter.
Filter Life Lasts a Lifetime Sawyer claims the filter will “last for a lifetime” if it’s properly cared for, cleaned regularly, and never frozen. It used to be a “million gallon guarantee”, but they can’t officially claim that anymore.
Filters Particulate? Yes Hollow Fiber Membranes typically filter particulate, and the Squeeze is no different. Get those nasty bits out of your water!
  • PointOne Filter
  • 2 32-oz. Reusable Squeeze Bags
  • Inline Adapters
  • Gravity Tubing
  • Cleaning Syringe
  • Mesh Carrying Case
Lots of included pieces in the Sawyer Squeeze kit. This allows you to mix and match to your heart’s content, creating a true squeeze filter, gravity filter, inline filter, or any combination. Also comes with a carrying case and cleaning syringe.
Works With Most plastic water bottles, Inline Hydration Bladders The included kit pieces make this work with many setups. The Squeeze itself can screw into most water bottles (like SmartWater), which most ultralight backpackers take.
Manufacturer Warranty Lifetime Warranty The warranty and filter life is the same on this product. As long as you don’t freeze it, this filter will work for a lifetime. Don’t expect it to filter viruses, and don’t use it after it’s been in sub-freezing conditions, unless you kept it warm.
Retail Price $39.95 A decent price for a lifetime filter and tons of extra accessories.

Gear Review of Sawyer Squeeze Water Filter System

Origins: Easing You In

I strolled through Domelands Wilderness feeling like a Disney princess. The excitement of new trails and adventure was in the air — all around me woodland creatures went about their merry way and the hills were literally flowing with streams and creeks. The plan for the long weekend was to hike low mileage, camp near a water source each night, and generally take in the views of a little-visited California wilderness area.


However, by the second half of our “easy 10 mile day” I was feeling less like Cinderella and more like Simba during that scary part of The Lion King where he has to wander through the desert. The idyllic mountain streams evaporated as we lost elevation, and my charming chipmunk friends were replaced by ominous bear tracks on a dusty faint trail. Still, I knew we’d be fine. The valley we were dropping into lost nearly 2,000 feet of elevation and was home to the Kern river, which was running high with spring melt.

As soon as I saw that river I knew the Sawyer Squeeze was about to get put to the test. The Kern was flowing high, fast, and brown. Really muddy, really dark, and really brown.


Revelation: The Moment I Knew

We stepped over downed logs and through dense willow bushes as we made our way to the shore of the river. Up close the water didn’t look as murky as it had from afar, however it conjured up images of black tea more than fresh river water.


A 64 oz. pouch dunking in the river. It may look clear in this photo, but it wasn’t. Trust me.

Squatting on the bank of the Kern river, in the mud next to freshly laid bear tracks, I quickly filled the 64-ounce pouch that comes with the Sawyer Squeeze Plus (not the Regular version). I screwed the Squeeze filter onto the pouch, tipped the spout into my water bottle, and squeezed. (In case you’re wondering, that’s how they came up with the name!)

The stream of fresh filtered water flowed out mercifully clear! I knew that Sawyer prides itself on filtering both bacterial and particulate matter from water, but I had yet to test their filters on anything but clear creek water.



Furthermore, the increased flow of the Sawyer Squeeze and the 64-ounce water pouch made filling my 2-liter bottles a total breeze. Until this trip I had only used the Sawyer Mini. It is a fantastic product (and very similar to the Squeeze), but has a noticeably lower flow rate. It can feel frustratingly slow when you’re tired at the end of the day and just want to get into camp. Even better, the Sawyer Squeeze took a fraction of the time of a traditional pump-style filter and we could even use the filtering pouch as a means of toting more water back to camp.

Digging Deeper

The Sawyer Squeeze itself is basic as it gets, and I love that about this product. One end receives water, the middle filters it, and it comes out the end. Boom. Done. There’s a pop cap that lets the water out as well as a handful of accessories that come with the Squeeze, which I’ll detail below, in addition to specifics about its use. For me, being a wilderness backpacker is not only about getting the lightest and most effective gear, it’s also about picking gear that won’t break and isn’t needlessly complicated, and the Squeeze excels in both of those aspects.


The filter. Water goes in one end, out the other. Pretty simple.

Ease of Use

Squatting on the side of a muddy river, surrounded by bear tracks, during the last moments of daylight is not the time to discover you don’t know how to use your filter. However, the Sawyer Squeeze is so incredibly simple that even first-time users should have no problems. Additionally, if you’re someone who likes reading instruction manuals, the Sawyer Squeeze provides instructions for both use and cleaning right on the water pouch!

Use the included pouch to scoop dirty water. Attach the pouch threads to the Squeeze unit. Then either squeeze the water into your water bottle, a hydration bladder, or your open mouth.


Simply screw the filter on the bag (or the bottle), and squeeze. And yes, those are instructions on the bag. The backside has backflushing instructions.


The filter itself feels very durable and sturdy. Short of running it over with your Subaru Forester, the Sawyer Squeeze is going to last you a long time. There are no moving parts, so the only real concern is using it in sub-freezing temperatures because the fibers can freeze.

The water pouch, however, is where I fear the issue will develop. The pouch is made of a tough plastic, but even after only a handful of uses this bag started to develop seams where I had folded the bag over to squeeze the water out. While none of these seams have sprung a leak just yet, I can definitely anticipate it being an issue in the future.


The Sawyer Squeeze works with the included pouch, or any Smartwater Bottle (and a few other disposable plastic bottles as well). It just screws on, and you can filter as you drink. It can also be rigged as a gravity filter or to sit inline with your hydration bladder, though this takes a bit more work.


The Sawyer Squeeze comes with two pouches, a syringe for cleaning the filter, as well as accessories for using the filter in-line with a bladder or as a gravity filtration system. You can even screw the filter directly to the top of your water bottle and drink through the nozzle.

For most weekend adventures a single pouch and the filter will do, making this set up incredibly easy and light. For longer trips, or trips with long water carries, I’d suggest bringing the cleaning syringe and pouch cap, which probably adds a whopping ounce.

Filtration Rate

As we learned while attempting to frantically filter water while checking over our shoulders for bears, the Sawyer Squeeze will filter a liter of water in about a minute. However, if you’re filtering tea-colored or muddy water, the filtration rate will slow noticeably on subsequent uses. This is a good indicator that your filter is in need of a cleaning, which you can do in the field with the provided injection syringe.


The flow on the Squeeze won’t blow your mind, but it’s pretty fast. About a liter per minute.


The only real issue that I take with the Sawyer Squeeze is that I fear the water pouch will eventually spring a leak. However, on their site Sawyer is quick to point out that their pouches are made of Mylar foil and will last hundreds of uses, so maybe I’m worrying over nothing.


These Mylar foil bags may not hold up over time. Many people swap them out after a while for something more durable, like a water bottle.

While I personally find the process of squeezing my water through the filter easy, and (dare I say it), kind of fun, some people have a distinct dislike for this type of filtration system. If you fall into the anti-squeeze camp, we suggest checking out our review of the SteriPen Adventurer Opti, a really simple UV filter.

Final Word

The Sawyer Squeeze takes the chore of filtering water and turns it into a quick and easy process. One that you can easily accomplish before being eaten by a bear whose prints you followed to your water source.

Where to Buy Sawyer Squeeze Water Filter System

We tested the Sawyer Squeeze Water Filtration System (sometimes know as the “Plus” system). This comes with the filter, two 64 ounce bags, one 16 ounce bag, inline adaptors, a gravity tube, a carrying case, and a cleaning syringe and gasket. The “system” is also offered in a Regular version, which has two 32 ounce bags and no cleaning gasket. Sawyer sells the bags separately and individual pieces of this set separately. It also sells the “All in One Water Filtration System”, which is the normal system with a bunch of add-ons.

In general, we think a backpacker will find the best value in the Sawyer Squeeze Water Filter System. This is the one with less stuff than what we tested. While the extra-large bags were nice, it wasn’t worth the extra $10, as you will probably end up using one bag and a water bottle. The Sawyer Squeeze kit we recommend retails for $39.95 — and that starting price is the best way to know which kit you’re purchasing.

One response to “Sawyer Squeeze Water Filter Review 2019

  1. mikesays:

    Your concerns about the bag is valid. One of the two supplied bags sprung a seam leak near the export tube on day 3, not only would dirty water then trickle down the filter and potentially into the clean bottle (we didn’t’ gravity feed, just squeeze), but it also prevented us from using the bag as a backup container while traversing an area of no water access without potentially getting all wet. A tape repair may have worked, but we didn’t feel we were in an emergency situation.

    Additionally, filling the bags with water from a stream or worse, a lake with waves even just lightly lapping, is extremely frustrating. Best I could consistently accomplish was a 2/4 – 3/4 full bag if the water was flowing just right or if I moved the bag through the water just right. Absolutely get a CNOC or something similar!

    The lack of an adapter (available separately) to connect a water bottle to the export side of the filter for the purpose of back flushing is a glaring miss; having to do it with the bulky syringe is seemingly ridiculous. We bought the adapter from garage grown gear and left the syringe home; works as it should.

    Love water Sawyer does around the work! Not impressed with the lack of an adapter and extremely disappointed with the bags.
