Fresh Step Perfume and dye free

I love the clumping ability and the odor control. It does track around the box, but not much beyond that. I originally chose this one because my cat is very fussy and didn't seem to like anything with a scent.

However, I am currently looking for something to replace it with because it is VERY dusty. Now, that may be because the 'perfume and dye free' is made differently than Fresh Step's other varieties. I have not tried the others.
