Key benefits Reliable multistage purification: removes scale, sediment, organic matter, dirt and chemical residues to improve taste and safety. Readytodrink water: the fourlayer filtration system delivers deeply purified water suitable for direct consumption. Fresher refrigerator environment: a builtin activatedcarbon layer reduces odors and helps keep fridge air fresh. How it works (materials and performance) Four filter layers: PP cotton (sediment capture), precompressed activated carbon (adsorption of chlorine and organic compounds), RO membrane (fine removal of dissolved contaminants), and post ultrafiltration activated carbon (final polishing). Each layer targets specific contaminants for comprehensive purification and improved water clarity and taste. Installation and maintenance Always check the product use and maintenance guide before installing. To install: slide the filter into the compatible housing and push until it locks in place. Replacement recommendation: the filter every 6 months for performance and water quality. Compatibility and form factor Intended for use in systems that accept this style of cartridge filter housing. Check your appliance's user manual or filter housing specification to confirm fit and compatibility. Constructed from PPcotton, activatedcarbon media, and RO membrane materials as described above. Practical use scenarios 1. Refrigerator water dispenser and ice maker: provides clean, tasting water and ice while reducing scale and contaminants. 2. Food and beverage preparation: use filtered water directly for drinking, cooking, or preparing baby formula. 3. Refrigerator freshness: the activatedcarbon layer helps reduce odors inside the fridge, keeping stored food fresher. Why choose this filter Comprehensive multilayer filtration for both particulate and chemical contaminant control. Designed for straightforward installation and regular maintenance to maintain performance. Produces filtered water that can be consumed directly while also contributing to a fresher refrigerator interior.
