I received this shark air purifier with true hepa and absolutely love it. I use it in our office in our home. It is the perfect size for the room. It runs quietly. It is small and doesn’t take up much space. The black color is great because it looks nice sitting out. It truly does make a difference. My husband has allergies and sneezes a lot during the work day. Since I have put this in our home office my husband rarely sneezes during the work day that he is 8n the room with this air purifier. Now I need to get one for our front room .
