Product Description Professionally R&D: The coffee machine filter contains activated carbon particles, which effectively reduce limescale buildup and soften water. The filtered water is beneficial to human health. In principle, the filter should be replaced at least every 3 months, or according to the machine's requirements, to ensure a significant reduction in chlorine, heavy metals, and other harmful contaminants. Enhancement: The filter removes impurities from the water. It effectively filters impurities, retains essential trace elements, keeps the water clean, and provides pure filtered water for brewing coffee. Extended Lifespan: Onelen coffee machine filters extend the lifespan of your coffee machine and effectively prevent pipe blockage caused by limescale buildup.
