This is an excellent air purifier. I purchased 3 of them for my home during covid. I am a Massage Therapist and use one of them in my treatment space, as they were recommended during covid. It moves a significant amount of air on the high setting, to the point that clients have thought it was an air conditioner, but it's not. I like that the filter has a UV light. I use the other two around my home. The filter is quiet enough on the low setting that you can sleep with it and it effectively helps with cat dander, dust and removing cooking smells etc. I would highly recommend this air purifier, it's the best one I have every owned.
