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