Our Alkalizing Under Sink Water Filter System reduces or removes contaminants such as chlorine & heavy metals from tap water to offer the freshest taste to you. The perfect solution for any household. It is quick and easy to install and use, attractive, convenient, and effectively removes many contaminants from water while increasing alkalinity & oxygenation. This solid-state water filter uses the latest technologies that blend the adsorption capabilities of coconut shell-activated carbon with Eagle Redox Alloy and more. Water travels through an Alkalizing cartridge with our Ionizer media, containing magnesium & calcium to increase oxygenation & drive the pH higher. Water flows through our SMART special house blend of 2 types of coconut-shell GAC (including Catalytic) with 2 types of Eagle Redox Alloys (9500 & 6500) & anion exchange resin. This blend effectively reduces & removes heavy metals, chlorine & chloramine, pesticides & herbicides, pharmaceutical by-products & other inorganic substances such as petroleum byproducts. Ceramic and Tourmaline balls enhance the water and maintain a more alkaline pH.
