I use a large HEPA filter from Sears, for my ceramic workshop. It works very well, depending upon the particle size you want to remove. Keep the filters cleaned and changed and you will really see the difference.

Hoping I'm not jumping into the fire here, but the ionizing kind (we all know what I mean) have been proven to be almost worthless. Look at the Consumer Reports. Don't waste your money on them. (just my opinion)

I vent my HEPA out of the studio via a small vent cut into the wall, because the particle size of ceramic dust is very small and it would pass through the filter. You won't need to do that, because the dust is probably big enough to be caught in the filters.

They run a little over a hundred dollars, and do make a little humming noise, but you might want to consider that you and your family shouldn't be breathing the old plaster. While it is generally inert, (it doesn't contain silica, so isn't really something that contributes to silicosis) it still isn't good to be breathing.
