Who It's For

The ROES-50 is ideal for families, renters, or homeowners who want a compact under-sink solution that produces near-bottled water quality for drinking and cooking without ongoing bottled purchases. It fits kitchens where the homeowner can perform basic plumbing connections and follow clear installation steps.
