How It Works

A patented sequestering polymer inside the cartridge bonds with calcium and magnesium ions, preventing them from forming scale on any surface. Water remains naturally mineralised but loses its scale-forming ability.

• Drop the cartridge in
• Close the lid

That's it. 15 minutes. No tools, no plumber, no electricity.
