Waterdrop 15UB Under Sink Water Filter System — PFAS, Lead & Chlorine Reduction | NSF/ANSI Certified

Overview

The Waterdrop 15UB Under Sink Water Filter System offers compact, reliable filtration for municipal tap water. It installs beneath your sink and pairs with a lead‑free faucet to deliver filtered water right at the tap. Designed for cold water sources, it suits kitchens, apartments, RVs, and small offices without taking up valuable counter space.

What it filters

• PFAS and PFOA/PFOS
• Chlorine and unpleasant taste or odor
• Heavy metals and sediment
• Other larger particulates via multistage filtration

Advanced filtration media

Active carbon block and advanced media work together to provide efficient filtration. The carbon is sourced from natural coconut shells; please check for coconut allergies before use.

Certifications and safety

Made from BPA‑free and lead‑free materials, the unit is IAPMO certified for NSF/ANSI 372 and 42 standards. Third‑party testing confirms lead reduction and taste/odor improvement. For certification details, search WD‑15UB on the IAPMO site.
