• Units
• Composite cartridges
• RO cartridges
• Faucet cartridges

Match the full unit name, cartridge code and stage. A name such as PPC1 or RO1 can appear in different product families; it does not by itself establish a common mounting interface. Composite cartridges and RO cartridges occupy separate positions and are recorded separately. PPC and PCB assemblies can combine several treatment functions; their position and role follow the named host system.

Compatibility entries describe manufacturer claims about a cartridge fitting a named unit. They do not establish treatment performance for a water supply, certification, or equivalence between filter media.

Status

Reference layer only. No cartridge interface in this category has a project measured baseline. The initial coverage follows exact manufacturer replacement listings. Other brands and regional variants remain absent where an exact match has not been verified.
