I have installed 3 whole house water filters and am confused about
this question.

The first filter is the cheap rust and big stuff 20 micron filter.

The second filter is the 5 micron charcoal taste and odor filter.

The 3 rd filter is the very expensive 1 micron filter, which I can't
afford to buy, so I need your opinion.

Do I leave the 3rd filter empty or do I put two of the cheaper 5
micron filters in the 2nd and 3rd positions?

I thought charcoal was primarily for chlorine? Assuming you're on a
well, than you don't have that(I guess). Another disinfectant is
Chlorimine, which is tougher to filter out(another non well related
chemical).

I'm about to put in a well, and here's my uneduacated(at this point)
attack on my water.

Softener for the big stuff(Lime/scale/calcium and other hard water
makers) and a 3-tiered filter system. 20micron/5 micron, then at the
kitchen sink an RO filter.

The correct order is

Well to filter bank 20/5

Filter bank to Softener - resin tied to well water specific characteristics

Softener to RO

And while you are at it, a whole house RO will only cost you $2500 to
$3000 including the repressurization pump, and ALL faucets have great
tasting water.
