What are your BEST (maybe less-obvious) tips for avoiding cat smell in the house?

I've been a cat owner most of my life, but it's now been a couple of years without a cat since my old girl died, and we moved to a new house. We just got two sweet kittens and I want to make sure we don't start to get a stinky house--my husband is reallllly sensitive to the smell. What are your best tips? Particular kinds of litter, best practices, etc.?

ETA: I am so glad I asked this question. SO much good advice here. I'm starting with:

  • Air purifier (this already seems like a huge win)
  • Little UV light "deodorizers" plugged into living room and bedroom https://a.co/d/cKxbq85
  • Baking soda
  • Litter Robot (just ordered, I hope it's worth the price...)
  • Clumping unscented litter (starting with clay but may look into other options)
  • Pee pads around the boxes
  • Litter mats around the boxes
  • Will change out litter at least every 2 weeks and clean boxes
  • Frequent vacuuming and cleaning fur off furniture

Once we get the Litter Robot, I may use that plus one additional litter box, ideally stainless steel. (As you can probably tell, I'm extremely paranoid about there being even the least smell!)
