Cat owners please help!

How do you all deal with kitty litter micro dust?

I am 31 weeks and I clean/dust my house and wipe surfaces every week. If I do not, my stuff ends up in a layer of kitty litter dust/hair. Does anyone have a hack to reduce this or to be safer? I’m worried about baby when she’s here and if this will affect her.

I have an air purifier I will use in our main room and where she will sleep, however all the kitty boxes are out in the main living room (I have 3) and they all have tops but they do not have in and out flaps because my cats are brats. I have an open house concept so my living room, dining room and kitchen are all connected.

Any suggestions? 😬
