Tankless Water Heater Filter Replacement Cartridge with Scale Inhibitor Product

The Premiere AMF-SDR520 is the ideal replacement water filter cartridge for tankless water heater filter systems including the AMF-20S. It’s a premium cartridge that removes sediment from the water and contains genuine Siliphos®, a corrosion and scale inhibitor. A tankless water heater filter with scale inhibitor protects the heat exchanger in your tankless water heater and helps avoid tank failure. Recommended for commercial and residential tankless water heaters and boilers from such brands as Bosch, Navien, Noritz, Paloma, Raypak, Rheem, Rinnai, Stiebel Eltron, Takagi, and more. Tankless units can become easily damaged by the sediment in the water supply, so this filter provides protection against sediment, scale, and hard water.

• Premium water filter cartridge with scale inhibitor to protect your heat exchanger and avoid tank failure
