Use unscented, clumping, cat litter. Good unscented cat litter doesn’t really smell like much of anything.
Run your bathroom fan, it will suck clean air from your house into the bathroom and flush it out so that even as you approach the bathroom youl be smelling air from the rest of the house and bad odours won’t build up.
Scoop the soiled, clumped litter into a green bin, and then tie the bag closed between scoopings.
Avoid “light weight” litter, that just means it’s lots of fine particles that are more likely to fly around.
