We've been living here almost a year now, and my wife has noticed a bit of a decline in water pressure. The good assumption, since the pressure valve coming out of the pressurization pump is still showing 65 psi, is that the filters are getting clogged. Since we removed the big monstrous stainless steel housing with the one micron lead removal filters, all that was left was a 25 micron filter (5" x 10" cylinder), a 5 micron filter (a 5" x 20" cylinder), and a 1 micron filter (another 5" x 20" cylinder).
So, how hard can they be to change? I couldn't turn the filter housings by hand, so I bought a filter wrench--which still wasn't easy! Whoever put these in place probably has fur on his knuckles.
Here you can see what the new filter looks like, and the old filters.

The shade is sort of an iron mineral color. The 25 micron filter had more crud in it than the others, but the 5 micron and 1 micron filters were indistinguishable in shade and amount of junk contained in them.
When one of the housings came off, I couldn't figure out if the O-ring that seals it went in the little notch at the top, or around the top of the housing. By putting it in the wrong place, I stretched the O-ring to a point where it would not go back in position. Do you have any idea how hard it is to find 5 1/2" O-rings in Boise? Fortunately, it is the same size as the GE Whole House water filtration system. Lowe's did not have O-rings for sale--but the guy there took pity on me, and gave me the O-ring off their display unit.
Anyway, all is back together again, and we have full flow once more.
