Product overview

Meet the Waterdrop WD-CFF-03 Replacement Filter, designed for WD-CTF-05 and WD-CTF-06 countertop filtration systems. This filter emphasizes efficient contaminant reduction while preserving the overall water profile. Note: it does not reduce total dissolved solids (TDS).

Built to fit your daily routine, the WD-CFF-03 emphasizes practical improvements you can feel in every glass—cleaner taste, clearer appearance, and a fresher mouthfeel—without overpromising results. The emphasis is on delivering consistent coffee, tea, and drinking water experiences from your tap.

Five-stage filtration and third-party verification

The filter employs a five-stage filtration system that addresses sediment and chlorine, while also reducing scale, heavy metals, hydrogen sulfide, and fluoride. Third-party laboratory testing confirms its ability to target common tap-water substances, supporting a confident, everyday water filtration routine.

• Stage 1: sediment filtration for clarity
• Stage 2: chlorine reduction for better taste and odor
• Stage 3: scale control and mineral balance
• Stage 4: heavy metals reduction
• Stage 5: fluoride reduction
