No dust. Yeah.  House smells like cat poop, even when scooping TWICE A DAY for my kitten. ICK!  My husband, who cannot smell anything...even smells cat poo. YUCK!  I only used it for my post surgery kitten.  I will be happy to go back to clumping, heavy, dusty cat litter.  At least my house didn't smell horrid.  P.S.  We also have carbon filters on the litter boxes and an electric air cleaner and it still smells bad.  FYI No diet changes...only change is the litter.  I do NOT recommend it unless you HAVE to use it.  I'm just grateful my cat will use it for right now and has not blessed our floor with poo or pee.
