This is a polyphosphate cartridge, a scale-inhibiting filter used to protect water heaters, boilers, and pipework from limescale buildup in hard-water areas. As water passes through, food-grade polyphosphate beads slowly dissolve and coat mineral particles (calcium and magnesium) so they stay suspended instead of crystallizing onto hot surfaces — it doesn’t remove hardness like a softener, but prevents it from forming scale. Commonly installed just before a water heater. Maintenance: Beads deplete over time and need refilling or cartridge replacement, typically every 6 to 12 months depending on water hardness and usage.
