What it cleans and how it performs

The WD-FUL12 is engineered for strong dirt absorption, helping to address contaminants like PFAS, lead, and chlorine, as well as taste and odor concerns. While it focuses on filtration performance, it does not alter total dissolved solids (TDS) measurements.

Certification and assurance

The filter element is IAPMO R&T certified against NSF/ANSI Standard 42 and NSF/ANSI 372 (lead) for reliability and safety. This certification supports confidence in the filtration you rely on daily.

Capacity, flow, and minerals

Designed for long-term use, the WD-FUL12 offers an 11,000-gallon capacity with a 12-month lifespan. The upgraded 3/8" outlet delivers a steady flow of about 5.026 L/min, helping your faucet deliver clean water without noticeable delays. The system keeps essential minerals while removing substances that may affect water quality. The activated carbon is derived from natural coconut shells, contributing to a sustainable filtration approach.

Notes and usage tips

• TDS is not a definitive measure of water quality; minerals remain in solution while contaminants are targeted.
• Please check for any coconut-shell allergy before use, as the carbon media is derived from this source.

Whether you’re refreshing your kitchen routine, filling a pitcher, or preparing beverages, this Waterdrop replacement aims to deliver a convenient, approachable filtration upgrade from your existing under-sink system.
