I can't even estimate how many thousands of heads I have repaired, checked and adjusted over the years... but for sure, there is no reason to discard the filter. Many reasons to keep it there. It also doesn't reason that multiple companies are manufacturing all those heads, selling as cheap as possible, yet adding a filter you need to throw away to make the nozzle work better.
Same people telling me to throw them away also tell me rain gauges don't work.

I understand that you need the filter to adjust the throw distance, but I have never seen any technician actually adjust the throw distance. They just use another nozzle. I have had technicians tell me that they routinely discard the filters because it reduces clogs and maintenance calls. Personally, I never clean a filter, I just throw them away. 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.
