The G3P800 uses the same G3-series filter cartridges as the G3P600 for pre-filter and carbon stages, but its own dedicated RO membrane. Here's the full schedule.
| G3-CF — Pre-filter | Every 6 months |
| G3-CB — Carbon Block | Every 12 months |
| WD-G3P800-RO — RO Membrane | Every 2 years |
| Note | Pre and carbon filters are same as G3P600. RO membrane is G3P800-specific. |
The pre-filter (G3-CF) and carbon block (G3-CB) are shared across G3P600 and G3P800. The RO membrane is model-specific — order WD-G3P800-RO for the G3P800, not the G3P600 membrane.
The G3 1-year combo pack (2× G3-CF + 1× G3-CB) covers both G3P600 and G3P800 pre-filter and carbon needs. Buy this annually. Order the model-specific RO membrane separately at the 2-year mark.
Same 3-second process as all Waterdrop G-series systems. Twist out, push in, done. The smart LED faucet automatically resets the indicator for each filter when a new cartridge is installed. Annual cost runs approximately $90–$130 depending on whether the RO membrane needs replacing that year.
