I have one of the Coway ones for fire season. It is quiet and nifty looking. It should help a lot, but it's more for large particles like viruses and dust.
Many of these air filters are not rated for food smells (or poop smells) which are physically smaller than the particulates for which they're designed, but I think they still help. Some have carbon filters which help with smells. (Methane molecules, for example, are way smaller than a virus...)
For litter boxes, I might upgrade to the ones designed for smaller stuff because, well, you know. Cat poop. :) On the other hand, the filters for those will cost more and probably fill up rapidly in a catbathroom. (I don't know--maybe they have prefilters for big chunks? I haven't investigated those but I wouldn't be surprised.)
If you're brave, there's a subreddit on air filters and you can learn more than you want to about what types of HEPA, etc., filters do what.

It's a solid flavorful meal.
