Why the RT-CF

First Line of Defence

Filtration Technology

Coconut-Shell Carbon

Powered by activated coconut-shell carbon, the CF pre-filter captures particles as fine as 2–5μm — significantly reducing chlorine, sediment and other impurities while improving the taste and clarity of every drop that follows.

Pre-Sediment & Carbon Block

Protects the Membrane

As the system's first stage, the CF traps colloids, sand, rust, chlorine and odour before water reaches the RO membrane and CBM mineral stage — shielding the core filtration and reducing contaminants like fluoride, PFOA, PFOS and VOCs across the full T3-M system.

Capacity & Lifespan

Up to 6 Months

A single CF cartridge keeps your water clean and fresh for up to 6 months of normal use — up to 1,056 gallons, the equivalent of around 8,000 standard 16.9 oz plastic bottles. Replace on schedule to keep the whole system performing at its best.

Replacement

Swapped in Seconds

The twist-and-pull, pre-assembled cartridge replaces in seconds with no tools and no mess. Compatible with WD-T3-M (and WD-T3-C, WD-T4-A). After fitting, hold the CF button for 7 seconds to reset, then flush for 15 minutes.
