Watts Pure H2O Lead Filtration System with supply line adapter


Protect what matters most with the Watts Pure H2O Lead Filtration System, certified to reduce 99.2% of lead, providing a simple, low-cost solution for your family's water. That's a benefit whether you are drinking the water, cleaning with it, or cooking with it.

The high-capacity, 1.5 GPM full-flow filter is certified to reduce lead, cysts, sediment, and chlorine taste and odor. The filter is changed with easy, quarter-turn replacement. The Lead Filtration system is capable of running at low water pressures, does not require a separate water holding tank, does not alter the pH of the water, and does not require electricity. It attaches easily and readily to your current faucet. No drilling is necessary.

Lead is harmful to your health and is especially injurious to children, who are still growing and developing. The EPA and the Centers for Disease Control and Prevention (CDC) both agree that there is no known safe level of lead in blood.

Whether or not you've confirmed the presence of lead in your water, you can rest assured that the Watts Pure H20 Lead Filtration System will provide a continuous, on-demand supply of premium quality drinking water directly to your tap.

The H2O-DWCFL100 Filtration System uses a Single Stage Filtration.

Filter life may vary based on local water conditions, use patterns, and frequency of filter changes. Recommended replacement of filter every 6 months or 4,000 gallons.
