I wanted to get any thoughts and suggestions on setting up a 3 stage whole house filter for a well. The idea is to take the individual whole house filter and put 3 of them in series together.
First, I would be using a filter strainer to get any large debris (250 to 150 microns), then the stages would be 50 micron, then 5 micron, then 1 micron.
Well -> Storage -> PreFilter(150) -> Stage 1 (50) -> Stage 2 (5) -> Stage 3 (1)
I know you can buy 3 stage units but they charge around 170 to 200 and buying single whole house filters cost 25. Granted I still need to buy connectors and piping for each but the total cost will still be lower.
Does this sound like a decent whole house solution? Does the 3 stage units do something different than just a series?

I've installed many filter systems this way, it's very common.
(random from web; not my install)
Installing the filters themselves is pretty straight-forward, with a couple things to note:
As far as safety of the water, that's a bit outside the bounds of this question, but just to highlight the point: it's a good idea to get your water professionally tested.
Sediment filters are good, but they do not filter everything. Absolute 1 micron (as opposed to just "1 micron") filters are effective at removing some bacteria, but they are not as effective as a UV lamp. There are many other types of contaminates (iron, manganese, pesticides, etc) that are not treated by this type of filtration at all.
