The filter elements in a reverse osmosis system are divided into two categories:
- Standard Filter Cartridges (excluding the reverse osmosis membrane):
These cartridges need to be replaced annually if the daily water consumption is around 5 liters. The cost for a set of these cartridges ranges from 80 to 110 euros.
- Reverse Osmosis Membrane:
The membrane cartridge requires replacement every two years. The cost for this cartridge is between 60 and 80 euros.
