My own well has a problem with rust. The water was so bad that it
would clog a filter in a couple of days and I couldn't even wash cars
with it. And the more water I'd use, the worse it would get. Finally
I called a drilling company in desperation.

They sent a crew out to pull the pipe from the well (plastic,
thankfully), raise the pump a few feet, and run all the water out of
it. It ran straight out of the well pipe onto the yard at full blast
for 45 minutes. So much rust came out that it actually stained the
yard. About half way through it started to clear up and was pretty
much clear water at the end.

Now I run the garden hose for a couple hours twice a week or so, and
it's almost crystal clear all the time. Combined with 35 micron
filters (used 5 micron before), the filters last for months.

Oh, and if you haven't already installed two filters in parallel, I'd
recommend it. Two filters last much more than twice as long as a
single.
