I have been using Dr. Elsey's blue multiple cat variety of litter for years (I think I switched to it back in 2014). I was using it in my LR3 and would get that horrible wet litter streaks all over my gray (with black liner) unit. It looks hideous.
So when I got my PuraMax, the BoxieCat Pro gray bag that I had heard was a good litter was also on sale. I grabbed a bag of it for the PuraMax. I have liked it a lot so far, much smaller particles than I was used to. It's kep my PuraMax looking good unless I'm just not wiping it down occasionally.
I bought several more bags of it, but still had approximately 2 big bags (40lbs each) of the other stuff. I've been using the BoxieCat in the PuraMax and a regular litter box in my kittens cat cage. I'm FINALLY down to the very last bit of Dr. Elsey's for the LR3, so I'll be deep cleaning that one and starting fresh with the BoxieCat in it and get to see how it does in that. Probably not any worse, most likely better.
I use Arm and Hammer Cat Litter Deodorizer powder in the new trash bags that collect the used litter, I just sprinkle some in when I switch out the bags. It helps to keep that compartment/drawer a bit more fresh and helps absorb any moisture as well. I use odor absorbing gel/beads air freshener in my apartment like Fresh Wave or Arm and Hammer Fresh Scents. That's usually enough to keep my apartment fresh.
I do have air purifiers I can run if needed (one is the small plugmount by Hamilton Beach), and if you have a strong smell that you want to get rid of quickly, putting out a small amount of white distilled vinegar in a glass will do the trick. Vinegar attracts the bad smelling particles like a magnet and absorbs it. You only smell the vinegar at first or if sniffing right over the glass.

Fresh Wave makes a similar pod with slightly different beads in the packets as well as a gel you can pour in other containers. I have a FW bead pod inside the lid of my trash can on the trash side of a double recycling/trash Simple Human bin. It helps a bit in it, but still not the best.
The gel form factor in containers though works fabulously and I believe is well worth the $$. I got a few small containers at first and then I've been doing the large refill ones.
This other Arm and Hammer Pet Scents deodorizer also works fairly well.
