How do I know when it's time to change the filter of LifeStraw Max?

If you continue to experience little to no flow-rate, it may be time to replace your membrane ultrafilter set. Water will stop flowing through once the membrane ultrafilter set has reached the end of its lifecycle.

If you start to experience bad taste, it may be time to replace your carbon filter. This filter lasts 4,000 gallons (15,000 liters).
