I suggest a particulate filter for everything (a screen type). These you back flush about every six months or as needed.
I recommend a water softner ($500) for water used to wash dishs and cloths, take baths, etc. I use five bags of salt about every 4-6 months at $4 per bag. Even at that you may get some orange like in the toilet tank. So periodically, throw a half of a cup of iron out into the tank. That will knock out iron bacteria, and cut the iron.
Untreated water will turn things orange (like my fence and drive way).
Drinking water, ice, etc. we use a carbon micro filter and process the hard water. It gets changed about every six months and runs about $30.
Sams club has a reverse osmosis system for about $160 that might work for your drinking water. I need to do more research on that as it's almost too inexpensive to do much.
Some thoughts. It's just part of the cost of living away from the city...
