Puretec SF240-CH Double-Life Carbon & KDF Shower Filter System 

The Puretec SF240-CH is a high-performance shower filter system designed to improve the quality of your shower water by reducing chlorine, sediment, heavy metals, odours and other common impurities. Featuring a double-life* replaceable filter cartridge housed in a durable chrome-finished body, the SF240-CH enhances comfort while helping protect your skin and hair from harsh contaminants found in mains water supplies. The combination of premium carbon media and KDF (Kinetic Degradation Fluxion) filtration ensures reliable, long-lasting performance with noticeably cleaner water from the very first use.

Engineered to fit standard ½" shower arms, installation is simple—just attach between your existing shower arm and shower head (shower head not included). The system uses a two-stage media blend where carbon effectively targets chlorine, chemical odours and organic impurities, while the high-purity KDF granules help reduce metals such as lead, mercury, iron and chromium through an oxidation/reduction process. This improves water clarity, reduces irritation, and provides a more pleasant shower experience for the whole

For best performance, the SF240-CH cartridge should be flipped at three months to extend its life and replaced every six months. Designed for everyday mains water conditions, the unit operates between 138–550 kPa and 2–50°C. With easy DIY installation, universal fitting and consistently cleaner water, the Puretec SF240-CH offers an affordable and effective upgrade to any bathroom.
