Questions about plumbing systems, minerals vrs chlorine

I use a whole house filter on the input water. I use either a sediment cartridge or a charcoal cartridge depending or whether I intend to store the water in my tank for a while. The charcoal cartridge removes chlorine and also acts as a sediment filter (5 microns as I recall).

In hard water areas I use a FloPur Mark 8000 water softener after the filter.
