Set of 3 Vitamin C replacement cartridges for the MineralStream BLACK Vitamin C Filtration Shower Head — the only MineralStream model that uses the BLCK Vitamin C cartridge system.

• Each cartridge holds a concentrated Vitamin C block in micro-porous media that neutralises chlorine and chloramine on contact for softer, healthier water.
• Vitamin C reacts chemically with chlorine to neutralise it (rather than just absorbing it like KDF or carbon filters) — a well-established method.
• Each cartridge lasts ~2–3 months, so a 3-pack gives 6–9 months of protection.
• Tool-free swap: unscrew the handle, slide out the old cartridge, slide in the new one, reassemble.
