Cost Per Liter

costpicSawyer filters are a sound investment since each one can provide up to 500 gallons (1890 litres) of potable water a day, and can last 10 years or more. A single filter can provide for a family or a community at less than a fraction of a penny per liter.

Sawyer filters are also a one-time only investment since they can easily be cleaned with the provided backwash syringe, there are no catridges to replace, no moving parts to break, and no power source needed.
