Features

First, we have to talk about the filter capacity of the Sawyer Mini. By that, I mean the amount of water this filter can process before it is no longer safe or functional.

Sawyer rates that at 100,000 gallons! To make that number a little easier to understand, that’s enough water to supply a family of four with drinking water for 136 years! I am sure the filter itself would break long before then, but it’s still an impressive number.

As long as your filter does last, it will essentially manage to remove all bacteria and protozoa from your water. It also removes any turbidity from the water, improving its look and taste. It will not remove viruses, chemicals, or anything dissolved in the water like heavy metals or salts; those take far more sophisticated systems.

The Sawyer Mini also boasts a variety of ways it can be used. The standard would be to fill the included bag, attach it to the filter and squeeze the water into a drinking vessel.

You can hook the Mini in line on a hydration bladder, screw it onto a standard water bottle, drink straight from the source using the included straw, or use it like a gravity filter by hanging it from a tree.

Pros

The Sawyer Mini Water Filtration System is by far the most affordable for what you get on the market—ranging between $20.00 and $25.00, depending on where you look. They also come in a 4-pack for around $70.00.

This filter is easy to set up and use in any of the setups it was designed for (I did not test the hydration bladder setup, which requires an adapter. Sawyer did not mention this on the box). The filter performed well with no leaking or clogging. After each use, it was easy to backflow the filter to clean it using the included syringe.

There is no way to test the capacity of this filter that I could come up with; 100,000 gallons is a LOT of water. But if that number is even remotely correct, this filter will be lost or broken long before you ever need to worry about the filter element going bad on you.

The size of this filter adds to its versatility. Even carrying everything this filter comes with (Filter, 16oz bag, straw attachment, backflow syringe), I could fit two or three in my cargo pocket and barely tell they were there. The syringe is the largest piece of the whole setup.

Used in the “squeeze” setup, the filter had a pretty solid flow rate. Probably close to half a gallon a minute, but it isn’t easy to test with only a 16 oz bag. Sawyer does make bags up to 64oz, which are very affordable and highly recommended.

Cons

The body of the filter is made of rather thin plastic to keep it lightweight but also make it more fragile. In a long-term survival setting, having anything that could break easily could be detrimental.

When screwed onto a bottle or as a straw, it was quick to deploy but difficult to drink from. At least difficult enough to make it a chore. The same would probably be true if set up with a hydration bladder.

Used as a gravity filter, it was hands-free, and I could do other chores while it worked, but I think the flow rate leaves a little to be desired. With just a 16oz bag, it’s not worth the setup time. Larger bags would make this much more viable, but I still think a dedicated gravity system would do much better.

Filling the bag from a stream is a lot harder than expected. Finding a deeper pool did help. This filter may be difficult to use if you live in an area with scarce water supplies. I would personally like to see a zip-top bag like a lot of gravity filters use.

Conclusion

Some of the Sawyer Water Filter Mini setups are more versatile than others, and the construction may leave a little to be desired, but you are getting a filter that has a long life, works well, and will not break the bank!

I think I would want a more sturdy option as a primary filter, but I still say buy a 4-pack of these and put one in the home first aid kit, one in the truck, one in your bug-out bag, and one in the hunting vest. If needed, buy a few more to stick in the boat, RV, or anywhere else you can think of. The Sawyer Water Filter Mini is a great little filter for the money!

I would recommend spending a few extra bucks and getting some of the 64oz bags if you do decide to get this filter. This Sawyer Water Filter Mini is one of the best lightweight filters.
