To me, the only purpose the filter has is to protect a nozzle that you can buy for less than 2 dollars. I understand that this may not apply to rotating sprinkler heads, which I don't have.

I think a main irrigation filter is the answer. Since I've installed one years ago, never had any problems with the spray heads. Especially the small ones spraying my flower bed. I make a couple of adjustments periodically if I see something not right but that's about it.

I like a filter in the line. Before the valves or after the valves? Both? They do require maint. of course, but most of what I find clogging heads is either a bit of pipe glue that finally came loose from the install or work, crap that got in the pipe when someone else worked on it and didn't flush lines at all, lots of stuff that is actually growing in the lines themselves. Even parts of valves that are wearing. Nothing stops us from needing to do occasional maintenance, and just good ol' walk arounds looking at every head on every zone.
