HALO Ultra Plus RO filter cartridges and drinking-water faucet

How it works

  • Sediment and carbon prefilters

    Two pretreatment stages prepare incoming water for the membrane.

  • Reverse osmosis membrane

    The membrane is rated at 50 gallons per day under manufacturer test conditions. A storage tank makes water available at the dedicated faucet.

  • Alkalinity stage

    A final filter adjusts the pH of the water after membrane filtration.

  • Service cues

    A filter-change light on the faucet and tool-free cartridges simplify routine filter changes. The system includes a leak shutoff device.
