This advanced composite filter cartridge is engineered by integrating high-performance activated carbon with food-grade polyphosphate powder, delivering a dual-action filtration solution tailored for hard water environments. The activated carbon component is responsible for the effective adsorption of chlorine, volatile organic compounds (VOCs), residual disinfectants, and unpleasant odors, significantly improving the taste and safety of drinking water.

Meanwhile, the polyphosphate powder acts as a powerful scale inhibitor by sequestering calcium and magnesium ions, which are the primary contributors to limescale formation. Through a process of chelation, it prevents these minerals from precipitating and depositing on internal plumbing surfaces, heating elements, and appliances, thereby extending the lifespan and efficiency of water heaters, coffee machines, and other household or commercial equipment.

This filter is ideal for use in regions with high water hardness or where scale control is a priority. By combining physical adsorption and chemical conditioning in a single unit, it ensures both aesthetic water quality and system protection. It is suitable for point-of-use (POU) or point-of-entry (POE) systems, and can be used in under-sink filters, countertop purifiers, pre-filters, or inline cartridges.

All materials used comply with food-grade and potable water safety standards, ensuring reliable performance without introducing harmful substances into the water supply.
