Restore Taste, Odor & Flow

New sediment and carbon filters reduce particulates, chlorine, and organics before and after the RO membrane—helping water taste fresh and protecting ice and beverages.

Protect The RO Membrane

The PB1005 sediment and GAC10 pre-filters capture grit and chlorine that can foul or damage the TFC membrane, supporting steady production between membrane changes.

OEM Parts, No Guesswork

This is the Sterling-specified pack for DWSB-TFC-50 and DWSB-50-PUMP; it replaces the exact filter types and sizes your system was designed around.

Simple Annual Service

Most installations change these filter stages about annually (more often with heavy use or challenging water). Follow the system manual and sanitize the housings during service.

Installer-Friendly Format

Standard 10″ cartridges and an inline post-carbon make swaps straightforward. The inline uses the IC10 series; your system may use IC10Q or IC10T—match what’s installed.
