Can an air purifier actually deal with cat odor, or does it just push the same air around the room? It is a fair question, because odor does not come from one place — it drifts off the litter box, rides on shed fur, and settles into soft furnishings.
A purifier works on the airborne part of that problem: its filter captures particles like dust, dander, and pet hair, and several models here add a layer aimed at smells. What it cannot do is replace cleaning the box or washing the blanket the cat sleeps on; it handles what is floating, not what is sitting in the carpet.
So the real buying question is not which purifier smells best, but which room it has to serve, and how much air it needs to move. The five below range from a desk-sized unit to one built for 2500 sq ft, and the right one follows your floor plan.

Before You Buy: A Few Things Worth Doing First
Measure the room before anything else. Coverage figures here run from a desktop unit to 2500 sq ft, and an undersized purifier in a large open-plan space will run constantly without ever catching up. Match the square footage first, then compare features.
Price the filters, not just the machine. Nearly every listing here flags replacement filters as an ongoing cost, and the washable filter on the large-room model is the exception worth noting. A cheaper unit with pricey filters can cost more within a year.
Decide how much noise and tech you want. Sleep mode matters if the unit sits in a bedroom, and several models here have no app control or air quality sensors — fine if you want a simple machine, a drawback if you want the purifier to adjust itself.
Put it where the odor starts. A purifier near the litter box area or the room the cat favors does more than one tucked in a far corner, and it still works best alongside regular box cleaning rather than instead of it.
