The system includes mechanical filters for preliminary cleaning of sand, rust, organic compounds, chlorine, ammonia, as well as most viruses and bacteria. Since the water at the outlet is practically distilled, after cleaning it is usually subjected to mineralization to give it better organoleptic properties. There are reverse osmosis systems of various degrees of purification (for example, three-stage or five-stage filters).
Reverse osmosis filter systems have high performance – up to 100 liter of water. However, to get a liter of purified water, about two liters will be drained into the sewer.
