1 microns absolute — the same filtration standard used in medical dialysis equipment. It removes 99.
99999% of bacteria and 99. 9999% of protozoa, numbers that meet EPA drinking water standards without chemicals, pumps, or batteries.
The filter weighs three ounces. It processes one liter per minute by squeezing water through a pouch.
And it is rated for one hundred thousand gallons before replacement, which translates to roughly a lifetime of backcountry use for any recreational hiker. Sawyer backs the filter with a limited lifetime warranty, and the system is fully maintainable — a simple backflush syringe restores flow rate when the membrane slows.
At approximately $35, the cost-per-year over even a ten-year span is under $4. Compare that to pump filters costing $80 to $100 that need $40 replacement cartridges every season.
The Squeeze has become the default recommendation on r/BuyItForLife and ultralight hiking forums for a reason: nothing else filters this well for this long at this price.
