Experience cleaner, crisper water right from your kitchen sink with the Waterdrop RF10W-UF undersink replacement filter.

Why this filter matters

The RF10W-UF employs an advanced multistage approach to tackle common daily water concerns. The 0.01 μm ultrafiltration membrane works with an activated carbon block to reduce taste and odor, and to filter out a broad range of larger impurities. In third‑party testing under NSF/ANSI 53, the filter demonstrated lead reduction when used as directed. While results can vary with water quality, this cartridge is designed to contribute to a more consistent tap water experience in everyday use.

• Ultra-fine filtration: a 0.01 μm ultrafiltration membrane paired with an activated carbon block targets chlorine, taste and odor, and larger particles.
• Effective impurity reduction: tested for lead reduction under NSF/ANSI 53, with sediment and chemical impurities addressed.
• Safe materials: housing is lead-free and BPA-free, with activated carbon sourced from natural coconut shells.
• Long-lasting performance: designed for up to 1 year or 11,000 gallons with municipal water, depending on usage.

Simple, versatile installation

• Quick, tool-free replacement: twist-and-lock design lets you swap the cartridge in seconds.

In daily life, this replacement filter supports a convenient routine of fresh-tasting water for beverages, cooking, and family use. It’s designed to integrate smoothly with your existing Waterdrop setup, helping you maintain consistent water quality over time. For best results, follow installation guidance and replace the cartridge according to your system’s recommendations and local water conditions.
