With a $25 price tag and claimed 100,000-gallon filtration capacity, the MINI is a clear leader in value. It also lives up to its name, since it’s barely larger than the palm of your hand, and it weighs next to nothing. An included straw and squeeze pouch provide multiple ways to use the filter — you can even thread it onto the top of plastic water bottles commonly sold in vending machines. The Sawyer Mini only protects against bacteria and protozoa, which seems a little lacking, but this filter greatly exceeds NSF/ANSI standards for these two common pathogens. So, while this filter doesn’t provide the broadest protection, it’s efficient at removing what matters most.
