A dual-stage water filter is a great, cost-effective option for clean drinking water from both municipal and well water sources. Having a system installed at your kitchen sink or refrigerator allows you to get safe, great-tasting, filtered water in your own home, for a fraction of the cost of bottled water. The EcoPure ECOP20 Dual Stage Water Filtration System uses a 2-stage process that pushes your contaminated water through both encapsulated filters and out the dedicated filtered water faucet, reducing chlorine taste and odor, sediment, cysts, lead, and chemicals.
