  • City Water: Replace every 3-5 years depending on input water quality, water usage, and pre-filter change maintenance.
  • Private Well Water: Replace every 2-3 years depending on well water quality, and pre-filter change maintenance.

Stage-5 Carbon Filter: Replace every 3-5 years

  • It’s best to replace this filter when replacing the stage-4 membrane.

Note:  How do I know when to change the membrane?

When the Pure Water TDS reading starts to increase (easily detected by a hand-held TDS water meter from APEC), it’s time to replace the membrane and the 5th Stage carbon filter. Please see “Owner’s Manual” Part II for details on how to test your water’s quality and membrane using a TDS meter.
