| Part | What it is for |
|---|---|
| Pre-filters | Several stages ahead of the membrane. They take out chlorine and particles, without which the membrane fails quickly. |
| Membrane | The heart of the system. It outlasts the cartridges and is changed less often; each model has its own. |
| Storage tank | Osmosis produces water slowly, so it collects in a tank. The tank is what takes up most of the space under the sink. |
| Post-filter | The final stage before the tap. On some systems this is a module with added magnesium. |
Why a magnesium module
The membrane does not distinguish harmful from useful: along with hardness salts it removes minerals too. That is why the range includes modules with added magnesium, such as Pro Mg, which return it to the already filtered water. If that matters to you, check the stage list on the page of the specific system, because not every model has such a module fitted as standard.
Osmosis needs mains pressure. On upper floors and in areas with weak pressure the system works more slowly and the tank takes longer to fill. If your pressure is weak, it is worth saying so before buying: models with a pump exist, and the choice between those and an ordinary system turns on exactly this.
What is nearby
A simpler system without a tank is a flow filter. Membranes and cartridges are in Reverse osmosis membranes.
