An under-sink system is a complete installation.

  1. Check your feed water

    Confirm the model’s feed pressure, temperature and treatment limits. A system’s daily production depends on operating conditions.

  2. Measure the whole setup

    Allow room for the unit, its holding tank, service access, faucet connection and drain. Confirm power for the exact configuration.

  3. Check the replacement list

    C/M, UV and pump options change what needs maintaining. Match the model code, cartridge dimensions and connectors.

All 16 models, in one place.

C uses the C/GAC post-cartridge configuration; M uses the M/SMART configuration. P denotes the pump version in the model descriptions. Compare UV and UF layout for the exact model.

Stages are not separate cartridges.A stage count describes the manufacturer’s treatment sequence. It is not a count of replaceable housings or an independent measure of performance. The older chart and product copy also differ on tank capacity: confirm nominal volume, usable capacity, dimensions and the supplied power unit for your exact model.
