Replacement guidance
Plan approximately 30–40 minutes for a complete filter change
1
Shut Off and Depressurize
Disconnect the system from the faucet and allow all pressure to dissipate before removing tubing or fittings.
2
Record the Tube Routing
Photograph and label each tube before disconnecting the existing filters.
3
Replace One Stage at a Time
Match every filter’s flow arrow and stage position, then install the supplied fittings where required.
4
Flush and Check for Leaks
Pressurize slowly, inspect every connection, and flush all new filters before using the water.
Before purchase
Good to know
!
150 GPD only
The verified stage specification lists a 150 GPD membrane. The current short description mentioning 100 GPD should be corrected.

Alkaline and ORP results vary
Final pH, mineral release, and ORP depend on water chemistry, flow, contact time, and cartridge condition.
