Professional development: Coffee machine filter contains activated carbon particles that effectively reduce scale deposits and soften water. The filtered water helps maintain water quality. The filter should be replaced every 3 months or as recommended by the machine manufacturer to reduce chlorine, heavy metals, and other contaminants. Increase purity: The water filter removes fine impurity particles, effectively filtering out impurities while retaining beneficial microelements, keeping the water system clean and providing purified water for coffee preparation. Extend use: Onelen coffee machine filter elements help extend the life of the coffee machine and prevent pipe blockages caused by scale buildup.
