LifeStraw Peak Series | What is the flow rate for the Peak Series 3L and 8L Gravity Systems?Updated 2 months ago

When using the Peak Series 3L Gravity Bag as a Gravity System, flow rate is 1.7L per minute - empty the 3L bag in under 3 minutes! 

When using your Peak Series 8L Gravity System, the flow rate is 1.5L per minute. It will fill the compatible 8L storage bag in approximately 8 minutes! 

We recommend placing the Gravity system at high point and positioning the hose in a straight position to optimize the power of gravity!
