Don't forget you also need to look after your water boiler, as limescale can build up in there, and the boiler needs to be cleaned periodically.
This is why we purchased inexpensive water treatment systems from Leroy Merlin's.
We purchased three different individual units:
First one is for Sediment and fitted just after our water meter.
Second is for limescale and is fitted just after the first.
Third is for taste and smell, but also includes an antibacterial filter, and this is fitted under the kitchen sink.
We had a builder fit the first two, as we had to chase out the area below the meter, and fit a new, lockable cupboard to house the first two filters. Then I fitted the third unit myself under the sink, connecting it up to the cold water tap in the kitchen with flexi pipes, which we purchased from a local builders merchants called Big Mat, that way we have pure drinking water.
This way we save on the filters for the third unit, as why have drinking water going to your boiler, washing machine, etc.
I can't remember which one cost what, but the prices were under 50€ each, but they came complete with a filter cartridge, which is easy to replace, We also purchased some replacement cartridges, and they ranged from 17€ to 28€, and they last about a year each.
The builder charged us 180€ for all the work they did, which included the supply and install of the lockable cabinet.
