Sawyer Products Mini Water Filtration System Review.pdf
The size of this filter really 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 rate of flow. Probably close to half a
gallon a minute but it’s difficult to test with only a 16 oz bag. Sawyer does make bags up to
64oz which are very affordable and highly recommended.
The body of the filter is made of rather thin plastic in order to keep it lightweight but also
making it more fragile. I believe in a long-term survival setting, it could be detrimental to have
anything that could break so easily.
When screwed on to 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 is set up with a
Used as a gravity filter, it was hands-free and I could do other chores while it worked but I do
think the flow rate leaves a little to be desired. With just a 16oz bag it’s not really worth the
setup time. Larger bags would make this a lot more viable but I still think a dedicated gravity
system would do a lot better.
Filling the bag from a stream is actually a lot harder than expected. Finding a deeper pool did
help. If you live in an area with scarce water supplies, this filter may be difficult to use. I would
personally like to see a zip-top bag like a lot of gravity filters use.
