The Sawyer Mini Filter is installed directly in the drinking tube and cleans the water as it passes through the side walls of the micro-fibrous tubes. Harmful bacteria and protozoa get trapped in the outer walls and make water safe to drink.

• The Sawyer Mini Filter filters 100,000 gallons from freshwater lakes, rivers or streams; Sawyer filters are robust and can be backwashed and reused over and over; no replacement cartridges needed
• Removes 99,99999% of bacteria (salmonella, cholera and E.coli) and 99,9999% of protozoa (cryptosporidium and giardia), exceeding EPA recommendations for removal rates; no chemicals or batteries required
