WATTS – ONE FLOW+

OneFlow®+ Salt-Free Scale Prevention and Water Filtration Systems use a commercially-trusted, physical water treatment technology to keep scale from forming on pipes and reducing appliance life, along with a high-capacity water filter to remove foul tastes, odors, and sediments for better tasting tap water. A single, compact unit with dual cartridges replaces a space-consuming water softening system and water filtration system — using no salt, chemicals and electricity.
