Waterdrop TSB 8 Layer High Capacity Under Sink Water Filter

Highlights

• More Filters, Better Taste: This under‑sink system includes 3 filters for 8‑stage deep filtration, reducing PFAS, PFOA/PFOS, residual chlorine, fluoride, heavy metals, silt, rust, and cysts. Featuring KDF for heavy metals and a fluoride‑reduction resin that removes up to 97% of fluoride, it is IAPMO‑certified to improve taste and reduce chlorine while retaining beneficial minerals. It does not reduce TDS.
• Leak‑Free, Crack‑Resistant Construction: Built with stronger, age‑ and freeze‑resistant materials, this under‑sink system features a reinforced design that’s twice as thick. It has passed rigorous durability testing, including 400‑psi burst pressure, 100,000+ pulse cycles at 150 psi, and 300‑psi static pressure—ensuring long‑term reliability without leaks or cracks.
• Solves Clogging Problems: Our upgraded filter increases the dirt‑adhesion area by 20X, improving filtration capacity while significantly reducing the risk of clogging.
• Lifespan of Up to 18 Months: The three under‑sink filters last 6 months, 8–12 months, and 12–18 months respectively, providing extended service life. For storage, seal each filter in a separate bag and refrigerate (do not freeze) to maintain freshness for up to 30 days.
• 3‑Minute Installation, 3‑Second Replacement: Compatible with 3/8″ and 1/2″ cold‑water lines, this under‑sink system is a simple DIY install using push‑to‑connect fittings—no plumber or plumbing experience needed. Its twist‑and‑lock design lets you swap each filter in just 3 seconds.
• Dual‑Use Faucets for Different Needs: This under‑sink system includes a lead‑free brushed stainless steel faucet that fills a 12 oz cup in 5 seconds. You can keep your original faucet for tasks like washing produce, while using the dedicated filter faucet for purified drinking water—meeting both source‑water and filtered‑water needs.
• Not for Well Water or Hot Water: This system is designed for cold municipal tap water only. If using well water, ensure it is pre‑filtered first. For pre‑filtration options, refer to WD-PFK.
