Query: Honeywell 17000

There are several versions of this air purifier made over the years:1700017000N17000-SSome with permanent filters, some don't.I assume there are difference in material/components between the models and therefor the difference on perceived noise of the unit.The Honeywell brand purifiers are made by Kaz. Not Honeywell.
