- Filters contaminants: built-in multilayer filter element effectively traps sediments, rust and other particles, delivering clean water, preventing pipe blockages and extending the life of cooling water equipment. - Quiet operation: low-noise pump design ensures no disturbances at night and supports a peaceful living environment. - Refrigerator filter element: compatible with municipal tap water, bottled water and other water sources; automatically adjusts the filtration rate to maintain stable performance across different water qualities. - Refrigerator water filter: softens water by reducing calcium and magnesium ions, prevents scale buildup in water dispensers and ice machines, and lowers failure rates and maintenance costs. Use scenarios: - Home use with a fridge water dispenser and ice maker fed by tap or bottled water. - Environments with variable or hard water quality to protect cooling and dispensing hardware. - Quiet living spaces such as bedrooms or apartments where nighttime operation should remain unobtrusive.
