If you have what is called "red iron", you will see stains and sediment from the iron. The common cure is an "oxidizing filter". I had one in my old house. Got it a Grainger. Today they are most likely around $700-800. It looked like a smallish water softener. It had a tank that you put potassium permanginate in and it backwashed like a softener and discharged an iron thick liquid. Cost of supplies was about $50/year. The other type uses a 30-50 gallon mixing/holding tank. Liquid chlorine is injected into the tank when the pump runs. Every few months you need to flush the bottom of the tank through a valve near the bottom. Much lower operating cost (a few bottles of bleach a year) but you end up with slightly chlorinated water.
Clear iron contamination usually does not stain. If you have red iron, most filters, no matter how fine, will not remove it, just like hard water. They remove iron or iron rich particulate in the water, but not dissolved iron. You need to oxidize it to get it to precipitate out of the water, then filter it out.
If you are a DIY'er, check Grainger for 3P980, and put it in yourself.
