370 isn't much
I would not use a bunch of filters, rather just one and clean it out often or slip in a clean spare one. By restricting the air flow the motor may overheat, I donno. It probably wasn't designed to have a lot of resistance. Something about pressure levels maybe? The commercial units have a squirrel cage fan. What does your's have?
Any dust you capture is no longer in the room so whatever you can filter is a good thing. :yes:
