With the latest Hollow Fiber technology and the power of gravity, the AutoFlow microfilter is fast as well—up to 1.75 liters per minute without a single pump stoke. 4-liter reservoirs allow you to filter large quantities at once making it perfect for groups, while quick and easy tool-free cleanings maintain high flow rates on extended expeditions.
