FAQ
A reverse osmosis (RO) system is a water filtration system that removes dissolved contaminants from water using a semi-permeable membrane. It is one of the most effective methods for producing clean, safe drinking water at home.
Water passes through several filtration stages, including sediment and carbon filters, before reaching the RO membrane. The membrane removes up to 99% of dissolved impurities, and the purified water is either stored in a tank or delivered directly to the tap.
Reverse osmosis removes:
- chlorine and unpleasant taste/odor
- heavy metals (lead, arsenic)
- nitrates and pesticides
- bacteria and viruses
- dissolved salts and limescale-forming minerals
Yes, reverse osmosis water is safe for daily use. Most modern systems include a remineralization stage that restores essential minerals like calcium and magnesium, improving both taste and balance.
Standard water filters typically remove chlorine, sediment, and some impurities. Reverse osmosis systems go further by removing dissolved contaminants at a molecular level, providing significantly higher water purity.
The best system depends on your needs:
- tank systems are more affordable and reliable
- tankless systems provide faster flow and fresher water
- systems with remineralization improve taste and drinking quality
Key factors to consider:
- water pressure in your home
- available space under the sink
- daily water consumption
- maintenance cost
- whether you need improved taste (mineralization)
Tank systems store purified water in a tank, making them cost-effective but slower to refill. Tankless systems produce water on demand, offering faster flow, better hygiene, and more compact design.
A home reverse osmosis system typically costs between € 300 and € 500, depending on the brand, features, and configuration (tank or tankless).
In addition to the initial system cost, annual maintenance usually ranges from € 75 to € 120, depending on the number of filters and system type.
