The Rinnai 103000039 Scale Cutter Water Conditioning System Replacement Filter provides limescale prevention and corrosion control. It conditions water, decreasing mineral scale adhesion to the heat exchanger's inner surface. The filter keeps scale-causing minerals in solution, changes the shape of precipitated lime scale, and coats surfaces with a micro-thin layer.
This replacement filter softens and removes existing lime scale over time, protecting water flow in HVAC systems and heating equipment.
