KRAUS Bolden 2-in-1 Pull-Down Water Filter Faucet - Integrated Filter

In this review of the KRAUS Bolden 2-in-1 Water Filter Faucet, the conclusion is straightforward: it is for households that want a single, streamlined kitchen fixture that delivers both regular tap water and dedicated filtered drinking water without a separate secondary faucet. The biggest reason to buy is its integrated DuoPureTM two-line design, which keeps filtered and unfiltered lines independent to reduce cross-contamination while providing a commercial-style pull-down sprayer for everyday sink tasks. It suits cooks and homeowners who value a clean look and easy access to RO or undercounter filtered water.

Key Features

• 2-in-1 Integrated Design: Combines a commercial-style pull-down faucet with a separate drinking water outlet so you do not need a secondary filter tap, saving sink space and visual clutter.
• DuoPureTM Technology: Uses two independent internal lines to keep regular and filtered water separate, helping to prevent cross-contamination and ensuring purer drinking water.
• Reverse Osmosis Compatible: Connects to undercounter filtration systems including Reverse Osmosis, enabling filtered water for drinking or cooking without changing your main faucet.
• Single Lever Control: A single handle controls flow for both regular and filtered water with a simple rotate motion, simplifying operation and reducing the number of controls at the sink.
• Commercial-Style Pull-Down: The industrial pull-down spout provides reach and flexibility for rinsing and cleaning tasks while maintaining a polished kitchen aesthetic.
• Brushed Brass Finish: A warm, modern finish that resists obvious fingerprints and complements contemporary kitchen fittings.

Who It's For

The KRAUS Bolden is ideal for homeowners who already use or plan to install an undercounter filtration system and want the convenience of an integrated drinking water tap without adding a separate fixture. Its commercial-style pull-down head also makes it a good fit for people who do a lot of cooking and need a flexible, durable faucet for food prep and sink work.

It is less appropriate for buyers who need a complete filtration system included, since the required Reverse Osmosis or other undercounter filtration is not included, or for those who prefer a minimalist single-spout faucet without a dedicated filtered water outlet.

Pros & Cons

Pros

• Integrated 2-in-1 layout removes the need for a second filter faucet, keeping the sink area cleaner and simpler.
