Polyphosphate is a popular media for limescale and corrosion control, used in both point of use applications and point of entry applications. Examples of common applications include for water heaters, washing machines and combi boilers. Our Polyphosphate Media Filters are suitable for treating water with up to 500ppm of hardness. The treated water can be heated up to 75-80⁰C if heated above this temperature the Polyphosphate gradually loses its effectiveness.

How Often Do I Need To Replace These Polyphosphate Media Filters?
The cartridge itself is reusable, so only needs to be replaced if damaged. The media inside dissolves into your water and lasts for approximately 70,000L before it needs replacing. The clear outer shell of the filter makes it easy to see how much media is left inside.
