@Zebethyal: you're right, of course. I probably use my 3D printer less than you, and my filament is not nearly that cheap. I don't take any special precautions, though. The filament (which is not on a spool) just sits on the table behind the printer. Still, to clog my 0.4 mm nozzle, I'd need a 0.4 mm particle, and that's not dust -- that's sand, and not very fine sand at that. I doubt there's that much room between the filament and the PTFE liner, so I don't see how such a large particle could enter the hot end. And if the geometry of the chamber and orifice is reasonable, I'd expect any smaller particles to be dragged out by the molten plastic, rather than accumulate.
Anyway, my wife is going to embark on a venture that involves lots of 3D printing in PLA, so we're going to use the printer much more, and try cheaper filament too. We'll see how the J-Head fares then.
