BTW this is how my filters are looking. Water flows from right to left.
The filter on the right is the 1 micron sediment filter. It takes out 99% of the undissolved iron (all my iron is undissolved). Cheap filter does most of the work.
The center filter is the Iron Filter (expensive).
The left filter is a 0.5 micron carbon (expensive)
I moved the clear filter casing to the last filter, rather than the first. Since the first filter is hit will the bulk of the iron it fogged the glass up and you could not see anything after a couple weeks. So the glass was useless on the first stage. Moving it to the last stage filter I could monitor how much iron is getting to the last filter.
I've run ~6,000 gallons through and you can see there is no sign of iron. And fairly clean water is hitting the "polishing" filter.
Note: The "Pro's" don't tell you if the iron is dissolved or undissolved iron. You have a lot more options dealing undissolved iron vs dissolved. I bet most wells are exactly like mine in this area. My guess is the expensive filters will last me 2-3 years.
