A coffee shop and the Army Surplus Store were my two favorite hangouts while Dirt Road Girl was hospitalized during her battle with cancer last year. When I got a break, I’d walk a block, grab a cup of joe, cross the street, and browse cool man stuff.
Last week DRG and I visited the surplus store again. On the door was a 8 1/2 x 11 inch sign stating, “ATTENTION PREPPERS – WE HAVE SAWYER SQUEEZE WATER FILTERS IN STOCK!”
DRG needed a portable water filter for her 72 Hour Bag. I carry a MSR water filter in my bag. But what if we had to split up. Or she had to get out of dodge own her on? She needed her own filter that was simple to use and lightweight.
I love my MSR MiniWorks EX. It’s easy to clean in the field with no tools, attaches to my MSR Dromedary Bag, and removes bacteria and protozoa including giardia and cryptosporidia. The only drawback is it’s weight – about a pound with the accessories.
Pound, smound! One pound doesn’t seem like much, but I wanted to make DRG’s bag as light and efficient as possible. Every ounce she shaves off saves energy.
We picked up a Sawyer Squeeze Water Filter. It weighs 3 ounces.
With my yellow jacket stings shrinking, I set to the woods to do some testing. The weight, box and all its contents, was hardly noticeable in my test bag. I brought along my new Pathfinder cook set. A separate review is coming on this bad boy, I promise!
For three ounces, this is what you get:
- The filter ~ Hollow-fiber membrane with a pore size of 0.1. The MSR pore size is 0.2. Both are effective for filtering out parasites and bacteria.
- Three mylar squeeze bags ~ 16 fl. oz.: 9 x 5 / 32 fl. oz.: 11 x 6 / 64 fl. oz.: 12 x 8 inches
- A 60 cc syringe to back flush the filter (with clean water) to maintain proper flow as needed. You could also use this item to flush wounds in the field and other redundant uses.
Out of the Box Simplicity
There’s no breaking in this filter or big learning curve. Just fill one of the mylar bags with ‘dirty’ water from a creek or pond, screw on the filter to the bag, and start drinking. I filled the 64 oz. bag and filtered the water into my 32 oz. Pathfinder bottle in under a minute.
It’s important to wipe excess unfiltered water from the bag before transferring to your clean container. Drops of unfiltered water containing bacteria, protozoa, and cysts could cross-contaminate what you think is safe drinking water.
The filter comes with a pop-up spout found on some water bottles. This allows you to drink directly from the filter with a mylar bag of unfiltered water attached. Or you can squeeze water into a clean mylar bag or container for later use. The filter will also fit standard treads of water/soda bottles. I tried a cheapo brand water bottle and the male treads would not tighten in the filter. ‘Standard’ threads do fit.
Keep in mind that this filter, like all other filters on the market, will not remove viruses. Have a way to treat viruses via chemicals or boiling. Don’t roll the dice with water. Keep chemical treatments and fire in your kits.
This little Sawyer is rated (guaranteed) for 1,000,000 gallons. That’s not a typo. One Million! I have no way of ever testing to see if they are right. I don’t think DRG will ever get close to that number. It would take a lot of Platypus bottles to equal a million gallons. No way we will ever squeeze that much water. It may become a family heirloom.
I’ve seen videos of the Sawyer used at home to filter water from a 5 gallon bucket. I like this guy’s gravity inline filter set up:

You can’t live long without water. Whether you’re an ultralight backpacker, prepper, or outdoor enthusiast, you’ll want to have a safe, effective way to create potable water. The Sawyer Squeeze Water Filter is a great way to do that.
Before storing your filter after use, back flush the filter with a diluted bleach water mx from the included syringe. This will help dislodge any clogs and clean up any nasties left from dirty water. Shake all the excess water you can from the filter. You can even blow through clean end to help this process.
I would recommend this lightweight, simple-to-use water filtering system. For under $50.00, you can add one to all you kits. I’m buying one for my get home bag. I may add one as a back up to my MRS filter in my B.O.B.
Stay hydrated, my friends!
