Watts (WQTCBC-10) 10" Pre-filter Cartridge for Watts QT RO - Carbon Block
Watts WQTCBC-10 Carbon Block Pre-filter Cartridge
10-inch solid carbon block pre-filter engineered for Watts QT reverse osmosis systems. Removes chlorine, organics, and sediment before water reaches the membrane.
Activated carbon block protects your RO membrane
Solid Block Construction
Extruded carbon block provides superior contact time and removal efficiency compared to granular carbon. Reduces chlorine taste and odor while trapping organic contaminants.
Membrane Protection
Removes chlorine and chloramines that degrade thin-film composite RO membranes. Extends membrane life and maintains rejection rates in Watts QT systems.
Drop-In Replacement
Standard 10-inch cartridge fits Watts QT pre-filter housings without modification. Proper seal ensures bypass-free filtration.
Extended Service Life
High-capacity carbon block handles typical household water for 6-12 months depending on source water quality and daily usage volume.
Designed for Watts QT Systems
The Watts WQTCBC-10 carbon block cartridge is manufactured for Watts Premier QT reverse osmosis systems. Fits standard 10-inch filter housings used in Watts QT series configurations. Verify your system uses 10-inch cartridges before ordering.
