I switched from a Merv 8 to a Merv 11 filter, and it seems to reduce dust and the unit runs quieter. You could try a higher Merv filter, but I wouldn't leave it in for more than a month or so because it can reduce the supply air flow. Lots of different filters available on Amazon. A better selection than the local stores.
