I have pretty much exactly what you described. I do notice the static. I see dust clinging to the outside of the pvc and and sometimes i can feel it although in the few months ive had it, ive had no problems. I also asked my electrician about it and he said as long as there is no dust sitting in the pipes, its not an issue. This means that you shouldn’t have duct work thats to big. If your just using 4” with a 1.5 hp DC then you are totally fine.
