The Citymaster PRO+ utilizes High-Velocity (HV) softening resin combined with Aquatell's proprietary mix of filtration media (AQX) to deliver a softener + filter combination that delivers beautifully soft, filtered water to your entire home or cottage. This versatile system can be used to soften water where extreme levels of hardness, iron, or manganese exist or in large homes or cottages where high service flow rates are required.

The Citymaster PRO+ is built with 0.5 cubic feet of AQX media, significantly improving the taste, odour, and overall healthiness of the water for your entire home. AQX dramatically reduces chlorine, chloramine, and thousands of other contaminants for over 400,000 gallons (about 1.5 million Litres) of throughput. This media can be replaced in the future without the need to replace the softening resin. The chlorine/chloramine reduction capability of this media significantly increases resin lifespan and this is reflected in the 2 extra years of resin warranty for this model.

The combination of the Clack™ upflow-regeneration control valve and HV resin also means that incredible efficiencies can be obtained. The Citymaster PRO+ can regenerate using as little as 21 gallons of water and 3 pounds of salt achieving a Softener Efficiency Rating (SER) of 5,000 grains per pound of salt used.

This system ships with a heavy-duty sediment filter system to ensure your softener is protected and the water in your home is sediment-free.
