Clean, Filtered Water for Every Home

Waterdrop is a dedicated water filtration brand built around one goal: making it simple for families to enjoy clean, great-tasting water straight from the tap. Backed by a broad range of certified systems, it helps you reduce unwanted contaminants in your drinking water, whether you filter at the kitchen sink, on the countertop, or across your whole house.

Reverse Osmosis and Beyond: A Filter for Every Setup

At the heart of the lineup are tankless reverse osmosis systems in the X, G, and K series, which combine powerful filtration with a space-saving design that removes the bulky storage tank and frees up room under your sink. Models such as the G3P600 and G3P800 deliver strong flow while cutting back on water waste. For more flexibility, Waterdrop also offers countertop RO systems and attaching faucet filters like the CTF series, plus under-sink options, whole-house filters, and bottle-free hot and cold water dispensers that deliver instant water without kettles, fridges, or stored bottles.

Filtration You Can Trust

Waterdrop emphasizes independently recognized performance. Many systems are certified to NSF/ANSI standards, covering lead-free construction (NSF/ANSI 372), contaminant reduction claims, and the reduction of total dissolved solids (per ANSI 58). Depending on the model, filters reduce up to 99% of lead and address chlorine taste and odor and microplastics - increasingly important given that PFAS is estimated to be present in much of the nation's tap water. Certain models even remineralize treated water for a smoother taste.

Simple Ownership, Lasting Support

Waterdrop systems are built to be low-maintenance: membranes are long-lasting, filter replacements are easy to swap out, and a subscription program schedules replacement filters so your system keeps performing year after year. Every purchase is backed by long-term reliability, including lifetime technical support and 24/7 customer support whenever you have questions about your system.
