The DS220 is a two-stage, salt-free, point-of-entry system (full house) specifically designed for the reduction of chlorine, sediment and limescale accumulation on pipes, fixtures and appliances. Our systems do not demineralize your water and do not introduce salt into your water. Instead, we utilize a salt-free scale prevention media that prevents hard water minerals from creating scale, removes existing buildup and also provides protection against corrosion caused by chlorides, silica and iron. Our high-pressure housing is NSF certified and features an integrated head manifold. It utilizes our 5 and 1 micron, coconut carbon blocks which includes our proprietary scale prevention media designed to prevent and remove harmful scale build up, remove chlorine, chloramines, rust particles, dirt sand, volatile organic compounds (VOCs) and other impurities from your water. This wall mounted unit is designed to be installed at the water main entry point and will provide a flow rate of up to 14 gallons per minute (GPM). The standard inlet and outlet connections are 3/4” NPT and has a design pressure of 125 PSI with a maximum operating temperature of 113°F (45°C).
