Restored Waterdrop TSB-UF Ultra Filtration Under Sink Water Filter System, 9 Layer (Refurbished)

Waterdrop was founded in 2015 with a commitment to improving global drinking water quality. Dedicated to meeting global household water needs, ensuring water safety, and contributing to human well-being, Waterdrop provides filtered water access to people worldwide.

• 9-Stage Ultrafiltration (TDS Note): The Waterdrop TSB-UF under-sink system uses a 0.01 μm ultrafiltration membrane with KDF and ion-exchange resin layers to help reduce chlorine, taste & odor, fluoride, certain heavy metals, rust, sediment, sand, silt, and other particles. Not designed to reduce TDS.
• Dual-Faucet Convenience: Includes a lead-free brushed stainless-steel faucet designed for steady output (about 11.5 oz in 5 seconds). It provides a main tap for everyday use and a separate outlet intended for better-tasting water for drinks, cooking, and pet bowls.
• Easy Installation & Quick Replacement: Typically installs in minutes and supports fast filter changes. Compatible with 1/2" and 3/8" tubing for common under-sink setups.
• Expanded Filtration Surface: Accordion-style filter construction increases adsorption area to help maintain consistent filtration and reduce clogging over time.
• Service Life Guidance & Storage Tip: PP pre-filter life is up to 6 months, while the granular carbon and UF stages are up to 12 months (varies by water conditions and usage). For travel, seal filters in bags and store in the refrigerator (do not freeze) for up to 30 days.
