I've read about that, and I'll keep an eye open in that regard, but my understanding is that static electricity buildup is a problem only in dry climates. My shop stays right around 50% RH year-round and we here in Tampa, Florida have maybe 3 days per year where the RH outside is lower than that. I think I'll be okay in that area. Another thing about a system that is properly sized - motor, impeller, piping and other sources or resistance - is that you should not have any dust buildup in the piping anyway. And you bet, I'll have to check that once in a while also to see if that is a reality!
