It depends what your goals are.
Reverse osmosis is perfect if your water is not drinkable, it is drinkable without further treatment. It is routinely checked for contamination.
Water filters, well filter. There is some value in this but it is just a filter.
Water softener are ion exchange machines. They exchange the calcium ions which are attached to the h2o molecules making it softer.
By itself our water is drinkable it is also soft enough that suds form with our untreated water, it does not rapidly stain toilets or sinks...
All three can be purchased on Amazon or other outlets. No one firm has a better product. Physics are not changed by marketing. If you want any certain system I would buy the cheapest best rated product and DIY install or use a plumber.
