KRAUS Bolden 2-in-1 Pull Down Water Filter Faucet - Dual Line Design

Our review of the KRAUS Bolden 2-in-1 water filter faucet finds it best suited for homeowners who want a single, compact fixture that delivers both regular and purified water without a second spout. The faucet pairs a commercial-style open-coil high-arc spout with an integrated filtered-water tap, making it convenient for kitchens that use an under-sink reverse osmosis or filtration system. Installation is straightforward for someone familiar with plumbing, and the main draw is the DuoPure Technology that keeps drinking water on a separate line to avoid cross-contamination.

Key Features

• 2-in-1 water filter faucet: Provides instant access to filtered water for drinking and cooking without a separate dedicated filter faucet.
• Commercial-style open-coil spout: The high-arc design adds industrial styling and plenty of clearance for filling tall pots and pitchers.
• DuoPure Technology: Independent water lines for regular and filtered water help ensure you get 100% purified water when using an under-sink system.
• Pull-down sprayer with Reach Technology: The hose retracts easily and swivels for full sink coverage and flexible task use.
• Universal under-sink compatibility: Connects to most reverse osmosis and filtration systems for easy integration into existing setups.
• Wear-resistant finish: Brushed brass and matte black option resists spots and fingerprints for easier cleaning and a polished look.

Who It's For

The Bolden is ideal for homeowners with an under-counter filtration or reverse osmosis system who want a clean, single-faucet solution for both regular and purified water. It works well in kitchens that favor an industrial or commercial aesthetic and where a pull-down sprayer is useful for everyday tasks.

It may be less suitable for users who need an ultra-durable, commercial-duty fixture under heavy daily use, or for those who prefer a separate dedicated filter faucet due to plumbing layout or personal preference. Also note the under-sink filter is not included, so buyers must already have or plan to add a compatible system.

Pros & Cons

Pros

• Combines regular and filtered water in one compact fixture, saving counter space.
• Independent lines reduce the risk of cross-contamination between tap and filtered water.
• Pull-down sprayer and 360 swivel spout offer strong maneuverability around the sink.

Cons

• Some customers reported gasket failures and leakage over time, so durability can be mixed.
• Under-sink filtration is required separately; this faucet does not include the filter system.

Specifications

Our Verdict

The KRAUS Bolden 2-in-1 faucet is a practical choice for kitchens that need both a pull-down sprayer and a dedicated filtered-water outlet in one fixture; its DuoPure separation of lines is the defining advantage. It offers good value when paired with a quality under-sink filter, but buyers should be mindful of mixed reports about long-term durability and inspect seals periodically.
