Review on Okaysou Smart Air Purifier: 5-in-1 Large Room Cleaner for Pets, Asthma, Smokers - Remove 99.97% Dust, Pollen, Smoke Odor | 1000 Sq Ft | Washable 3 Filters by Theresa Jones

What do you not like? It works great, has a washable filter and covers a large area! I was starting to develop an allergy to pet dander which was really affecting my breathing. I bought this air purifier hoping it would help and it did. I no longer have problems being in the living room with pets. I put this downstairs in my living room and it's quite a large area and it seems to work really well. The highest setting can be a bit noisy, but I set it to level. 2 is quiet and still does its job. For some reason when I was cooking yesterday it didn't do a good job of removing the oncoming smell but I know it's working well because my dogs haven't had any allergic reactions to the air purifier. on. I would recommend it to anyone allergic to pet hair.
