in-line water filter gets clogged weekly after well-water pipe replacement
I'm assuming your pipes were quite old and that may be part of the reason it was replace.  In that case your experience is entirely normal although it's also quite inconvenient.  Working on old plumbing does disturb deposits and sediment that has collected over the years.  As noted, but best thing is to run the water full-force for some time.  5 minutes, however, is nowhere near long enough.  I'd start at an hour or so and continue until water collected in a bucket no longer shows sediment in the bottom after sitting a while.
