Waterdrop TSB 8-Layer Under Sink Water Filter — PFAS/Fluoride/Chlorine Reduction | Dedicated Faucet

Overview

Waterdrop's TSB 8-Layer Under Sink Filter brings cleaner tasting water directly from your municipal tap. Designed for cold water and under-sink installation, it pairs with a dedicated faucet and aims to balance safety with flavor by targeting common contaminants while preserving essential minerals.

What It Targets and How It Helps

The 8-stage filtration targets PFAS, PFOA/PFOS, residual chlorine, fluorides, heavy metals, silt, rust, and cysts. KDF materials help reduce heavy metals, and a fluoride reduction resin can remove up to 97 percent of fluorides, improving taste and clarity. Note that total dissolved solids remain unaffected by design, so beneficial minerals stay in your water.

• PFAS and PFOA/PFOS reduction may improve taste and odor.
• Fluoride reduction can enhance clarity and reduce aftertaste.
• Chlorine removal minimizes residual taste and odor for a fresher cup.

Certifications, Durability, and Reliability

NSF/ANSI 42 certified to support taste and odor reduction. Built with durable materials that withstand high pressure and long-term use, the system preserves minerals while filtering out the unwanted substances and is designed to minimize cracking and leaks.

• Rigorous pressure and longevity testing for dependable performance.
• Mineral retention supports natural taste without sacrificing safety.

Installation and Everyday Use

Set up in about three minutes with push-to-connect fittings. A separate lead-free brushed stainless faucet provides a quick pour, while your original faucet remains available for nonpurified tasks. Replacement filters swap in just a few seconds with a twist-lock design.

• 3 minute installation, 3 second filter swaps.
• Separate dispensers support purified and source water needs.

Notes for Choosing and Use

Use with cold municipal tap water. It does not reduce TDS and is not intended for well water. For well water, consider a pre-filtration step such as WD-PFK before the under-sink system. The system supports a maximum flow of 1.45 gpm and is designed for compact under-sink placement.
