If you want no dust then some kind of pellet litter would be best, like corn or pine pellets. My cats hate that texture though, so we had to find one with a similar texture to clay litter. I worked at a pet supply/food store for a couple years and tried a bunch of litters, nothing with a granular texture is truly dust-free, and I found clay litter claims of being “low dust” to be complete bullshit. I settled on Sustainably Yours Large Grain litter, it’s corn based. The large grain really reduces the dust, I get a little bit when emptying the bag but the large grain doesn’t throw dust when they dig around in it. It also clumps pretty well.
