The 3 main shower filter technologies

1. Activated carbon — best for European water

Activated carbon works via adsorption — chlorine molecules bond to the carbon's enormous surface area. Removes: free chlorine, VOCs, odours, some heavy metals. Doesn't remove: dissolved minerals (limescale), fluoride.

Best for: European municipal water where chlorine is the primary concern. Effectiveness: 90–97% chlorine removal. Cost: low (€13–20/cartridge, every 3–6 months).

2. KDF (Kinetic Degradation Fluxion)

A copper-zinc alloy redox reaction neutralises chlorine and some heavy metals. More effective for chloramines (common in US water). More expensive. Best for North American municipal water.

3. Vitamin C (ascorbic acid)

Neutralises chlorine and chloramines instantly. No filtration of other impurities. Cartridges last only 4–8 weeks. Used as a supplement to carbon, rarely alone.

What to look for

  • Filtration technology: activated carbon is sufficient for most European water
  • Cartridge lifespan: minimum 3 months for cost-effectiveness
  • Annual maintenance cost: factor in cartridge replacements, not just purchase price
  • Universal fit: must fit G1/2" (standard in Europe)
  • Pressure impact: look for pressure-boost features

Comparison: shower filter vs alternatives

Whole-house softeners: €1,000–3,000 + salt + installation. Under-sink filters: don't help your shower. A shower filter at €49.99 targets the exact problem at minimum cost.
