High-efficiency filtration: 40 micrometer stainless steel filter core captures sediment, rust particles and visible debris to deliver cleaner water to appliances and fixtures. Protects appliances and plumbing: reduces sediment and particulate build-up that can clog valves, nozzles and plumbing, helping maintain water flow and reducing maintenance needs. Minimizes limescale effects: designed to effectively reduce limescale buildup on heating elements and internal parts of water heaters and washing machines, supporting steady performance over time. Durable, safety-focused construction: reinforced materials and robust housing are built to withstand high water pressure for reliable, long-lasting use. Broad compatibility: fits standard 4-point interfaces for easy installation with many showers, faucets and related fixtures without special adapters. Simple installation and maintenance: removable stainless steel filter core is easy to clean and reinstall, keeping performance consistent with minimal effort. Practical use scenarios Before a washing machine: install on the water inlet to reduce sediment and lower limescale accumulation on heating elements and hoses, helping extend appliance life and reduce service calls. Ahead of a water heater: capture rust and particles before they reach the heater tank, minimizing sediment layering and improving heating efficiency over time. On a shower or faucet: attach to the fixture’s standard 4-point connection to improve water clarity, protect nozzles from clogging and reduce wear from particles.
