Why the RT-CBM

Pure Taste, Restored Minerals

Filtration & Mineralisation

Coconut Carbon + Minerals

Powered by activated coconut-shell carbon, the CBM filters particles as fine as 1–3μm — significantly reducing odour, bad taste and residual impurities. It then re-infuses your water with essential minerals (Ca²⁺, Mg²⁺, Na⁺, K⁺) for a smoother, healthier drink.

Capacity & Lifespan

Up to 1,056 Gallons

A single CBM cartridge delivers clean, fresh water for up to 12 months under normal use — roughly 1,056 gallons, the equivalent of around 8,000 standard 16.9 oz plastic bottles. Less waste, better water, all year round.

Replacement

Swapped in 3 Seconds

The twist-and-pull, pre-assembled all-in-one cartridge replaces in seconds with no tools and no mess. Its integrated seal is leak-proof, so installation is clean and foolproof every time.

Compatibility

Built for the T3-M

This genuine CBM replacement is engineered specifically for the Waterdrop Ultra-Saving Tankless RO System — compatible with the WD-T3-M (WD-RT34-WMA, WD-RT34T-WMA). After fitting, hold the CB button for 7 seconds to reset, then flush for 15 minutes.
