Why Choose a Reverse Osmosis Drinking Water Faucet?

A reverse osmosis drinking water faucet provides dedicated access to purified water from your RO system. RO faucets feature a dedicated line to deliver water filtered through an under sink filtration system, ensuring you have separate access to the water filtered for drinking and cooking. RO faucets with optional air gap functionality prevent contaminated water from backflowing into your purified water supply. These specialized faucets maintain optimal water pressure for RO systems while complementing your kitchen design with various finish options. By choosing a dedicated reverse osmosis water faucet, you ensure the best water filters for home deliver maximum performance and water quality directly at your sink.

Features of RO Water Faucets

SpiroPure RO water faucets feature durable, lead-free construction ensuring safe drinking water contact. The three-line configuration accommodates filtered water, drain, and optional air gap connections. For RO systems, the included optional air gap feature is required by some US plumbing codes to prevent brine waste from the RO process from mixing with the filtered water. Available in four premium finishes—brushed nickel, matte black, polished chrome, brushed gold (with limited supply of a fifth finish, antique bronze)—these faucets complement any kitchen. Spouts provide ample clearance for filling pitchers and bottles. All models include mounting hardware, adapters, and detailed installation instructions for straightforward setup.

FAQs on RO Faucets

What is a Reverse Osmosis Water Faucet and How Does it Work?

A reverse osmosis water faucet is a dedicated tap connected exclusively to your under sink or RO filtration system. The separate line ensures purified RO water never mixes with regular tap water, maintaining water quality. These faucets feature specialized connections designed for optimal pressure management.
RO faucets connect exclusively to reverse osmosis systems and handle the dedicated line and flow rates typical of filtered water. Regular faucets connect to main water lines with higher pressure and flow. RO faucets often include air gap capabilities for backflow prevention and use specialized quick-connect fittings.
Air gap faucets create a physical separation between drain water and purified water lines, preventing the possibility of backflow into your filtered supply. Drain water exits through a physical gap in the faucet stem before entering the drain line.
Dedicated RO faucets are designed for RO system flow rates and pressure requirements, separating water optimizing performance. You can direct the filtered RO line to the main tap in place of your regular cold tap water line, but even tankless units with booster pumps typically won't match standard water pressure.
Dedicated RO faucets can connect to other filtered water sources like under-sink carbon filters, though SpiroPure RO faucets are not recommended for use on standard kitchen faucet supply lines. RO faucets excel specifically with reverse osmosis systems, with or without the use of the air gap feature.
