Our TAC Water Filters use template assisted crystallisation (TAC) technology to treat hard water. They work by converting the limescale-forming elements such as calcium and magnesium into microscopic crystals that float freely through pipework without sticking to surfaces and causing limescale. Cartridges are available in all industry standard sizes, including 10” and 20” both regular and large diameters. The TAC media we use is independently tested, proving 99.6% efficiency using German DVGW protocol. Product Features Effectively treats hard water at 99.6% efficiency Long cartridge lifespan of up to 3 years Salt free alternative to water softening WQA gold seal certified media Choosing Product Size Choose a size based on your available space and flow rate requirements. We stock these filter cartridges in all industry standard sizes including regular diameter (2.5″) and large diameter (4.5″) including both 10″ and 20″ lengths. Most standard filter housings are compatible with these filter cartridges, but can be purchased separately if required. Help & Advice Need help or advice on which size to choose?
