Professional development: Coffee machine filter contains activated carbon particles that help reduce scale deposits and improve water quality. The filter helps reduce chlorine, heavy metals, and other contaminants. It should be replaced every 3 months or as recommended by the machine manufacturer. The water filter removes impurity particles, effectively filtering impurities while maintaining essential minerals in the water, keeping water clean and providing filtered water for coffee preparation. The Onelen coffee machine filter may help extend the life of the coffee machine and help prevent pipe blockages caused by scale buildup.
