1. Improve the purity of drinking water: By replacing the water filter in a timely manner, large contaminants such as sediment, rust, etc., are effectively filtered out, ensuring clean drinking water. 2. Enhance filtration precision: The filter element is designed for different water qualities, effectively capturing heavy metals, suspended particles, and other small impurities. 3. Protect the cooling system: The filtered water quality reduces scale buildup, preventing limescale accumulation in the condenser and evaporator, which could otherwise impair cooling performance. 4. Ensure safe drinking water for the whole family: Continuous replacement of the water filter provides clean water that meets drinking water standards for all family members.
