True. But beware, some of those cheap filters are just that. Nowhere near the performance of a true HEPA filter.
Given I originally got mine for allergy issues, you may not have an issue on this front. But I thought it worth mentioning.
Totally agree on the motor point. The original Honeywell motors have been bulletproof. The 53000 that I use in the bedroom has run 24-7 for at least 7 years, with only stops for filter changes and the occasional drop or two of oil.
