Features

800 gallons per day

No waiting for filtered water. Filtered water dispenses at 2.5 liters per minute; RO-purified water at 1 liter per minute.

Contaminant reduction

5-in-3 reverse osmosis filtration blocks dirt, rust, sand, iron, chlorine, cysts, salts, VOCs, total dissolved solids, and heavy metals like lead and arsenic. The final filter adds essential minerals back into your water.

2:1 pure-to-drain ratio

For every 2 cups of pure water dispensed, only 1 cup of wastewater is created, saving money and lessening environmental impact.

Compact tankless design

At 5.2” W x 16.6” H x 18.2” D, it occupies minimal space under your sink.

Smart faucet

Dual-lever design for filtered and RO water, plus a bright display with filter lifetime indicator.
