OK--it is not completely dust free but I cannot imagine any clay litter that would...but it clumps amazingly well and there is no odor--neither the overpowering perfumy smell of scented litters--nor the smells of cat p and p. The sand is finer than most litters--Cat seems to like to dig into it more than other litters...And it does last the advertised month. I live in a small apartment...I have been changing out litters every two and a half weeks before Boxiecat. The people at Boxiecat are really nice too. They love their kitties and I like the fact that you can set up automatic delivery.
