Looking for non toxic litter recs!!!

I’ve been trying to do research regarding different types of litter and what’s safest for cats but everyone seems to have opposing strong opinions. I have a 3 year old cat who has been using clay litter all his life, but i recently read that the dust isn’t great for their lungs and am looking to make a switch. Tracking and odor aren’t huge issues for me, my main concern is what is the least toxic to my fur baby. Do yall have any recommendations?
