your post reminded me I saw something the other day about corn kernal cat litter.It seems to me a type like this might not produce the amount of dust from other kinds. I don't know, don't have a cat

Maybe you could try that?
something like this product ( NO I am not affiliated with this site, info purpose only)

Oh another thought, have you considered a cool air humidifier? It might help hold the dust at bay.
Good luck!
