Waterdrop TSA 8 Layer Under Sink Water Filter System

Highlights

• More Filters, Better Taste: This under-sink system includes 3 filters for 8-stage deep filtration, reducing PFAS, PFOA/PFOS, chlorine, fluoride, heavy metals, and more. KDF targets heavy metals, resin reduces fluoride, and the IAPMO-certified CT filter improves taste—ensuring pure, healthy water.
• National Geographic Recommended: The compact Waterdrop TSA under-sink filter is endorsed by National Geographic. Its space-saving design fits easily under most sinks, and its quick-connect fittings enable simple, professional-free installation.
• No Leaking or Cracking: Built with strong, age-resistant, and freeze-resistant materials, this under-sink filter features a durable, thickened design. It has passed rigorous testing, including 400 psi burst pressure and over 100,000 pulse cycles, eliminating concerns about cracking or leaks.
• Prevents Clogging: Our upgraded filter increases the dirt adhesion area by 20 times, boosting filtration capacity and significantly reducing the risk of clogging.
• Lifespan up to 18 months: The three under-sink filters last 6, 8–12, and 12–18 months, respectively. For storage, seal filters individually and refrigerate (do not freeze) to maintain freshness for up to 30 days when not in use.
• 3-Minute Installation, 3-Second Replacement: Compatible with 3/8″ and 1/2″ cold water lines, this under-sink filter features push-to-connect fittings for DIY setup in under 3 minutes, and a twist-and-lock design for filter changes in just 3 seconds.
• Cannot Filter Well Water or Hot Water: This system is designed for municipal tap water and must be connected only to a cold-water line. If using well water, ensure it is pre-filtered (see WD-PFK for compatible pre-filtration solutions).
