## Features

- 【Efficient scale inhibition】This scale inhibitor's food-grade polyphosphate can inhibit limescale formation by preventing calcium and magnesium ions from precipitating and combining, and reduce corrosion by forming a protective layer on the inner surfaces of shower heads, water heaters, faucets, pipelines, and other pipelines.
- 【Energy saving】Reducing limescale on heating elements extends lifespan of water heaters, washing machines, dishwashers, and other water-using appliances while also improving efficiency and saving energy.
- 【Premium materials】The scale inhibitor system is made of food-grade, BPA-free materials and includes durable anti-rusting 304 stainless steel adapters.
- 【Stable flow】3/4”NPT inlet/outlet ensures a high flow rate of 10 GPM and keeps stable water pressure. Included Components：3/4” NPT inlet/outlet connection, Replacement Cartridge*1.
- 【Easy installation】Please keep this inline scale inhibitor system upright. By absorbing a small amount of polyphosphate, this system can better inhibit the accumulation of hard minerals on the surface of metal, ensuring a better scale inhibition effect. Please ensure that it is installed on a cold-water supply pipeline to supply water to the water heater.
- 【Long lifespan】This system can offer 6-month protection under normal use, but the lifespan may vary based on local water quality. It can be replaced easily with AQUACREST water filter with the model of AQU-WF65, making system maintenance easier.
