The Aquaphor Osmo Pro 100 EU reverse osmosis system filters water through a semipermeable membrane that, under pressure, allows water molecules to pass through while removing other contaminants. It includes Pro 1, Pro 100 and Pro HFM filters; the latter enriches the water with magnesium and calcium using dolomite. The filtered water is suitable for drinking, cooking and preparing infant food without boiling, and helps protect household appliance heating elements from limescale.

The Pro 1 combines mechanical and adsorptive filtration, using coconut-shell activated carbon, Aqualen ion-exchange fibre and a 3 μm mesh. The Pro 100 membrane provides molecular purification by reverse osmosis, while the Pro HFM contains a dense membrane and activated carbon to improve taste. Filters can be replaced without tools in under a minute.
