Waterdrop WD-CTF-05 Countertop Water Filter for Sink Faucet — 4,000-Gallon Capacity, Chlorine Reduction, Life Reminder

Smart filtration for everyday drinking and cooking

Upgrade your kitchen with a compact, user-friendly filtration solution that honors your tap water while keeping setup simple. The Waterdrop WD-CTF-05 countertop water filter attaches to a standard faucet, delivering filtered water on demand for drinking and cooking without complexity.

This system uses a dedicated faucet to keep drinking water separate from rinse water, helping your routine stay clean and efficient. It is designed to work with most standard faucets, but it does not fit pull-out, handheld, spray-style, or sensor faucets. If you are unsure about compatibility, share a photo and we will help you check before you purchase. Note that this model does not reduce total dissolved solids (TDS).

Certification, capacity, and what to expect

Independent testing confirms NSF/ANSI 372 compliance for lead content (≤ 0.25%), providing confidence in the filtration approach. The system filters up to 4,000 gallons, or roughly six months of typical use, depending on your water and habits. A mechanical life tracker on the countertop helps you schedule a filter replacement by letting you set the start month during installation.
