Those of you with asthmatic cats, what litter do you use?

So my guy has joined the asthma club this week on my birthday 😭 He's going to be 12 months old soon and super picky with litter. My country also has very very few litter options. We use a bentonite/clay litter which is the least dusty of the clay options here but I would really prefer to change tbh. My cat won't poop in anything that's pellet shaped. My country has a tofu pellet option and a pine/wood pellet option... multiple clay options, and then it's on to non-clumping options. I'm wondering what everyone else does?
