It covers a large surface of my home. It's lightweight, helps cleans the air and gets the viruses and bacteria out.  I like that it has a sensor light to let me know the quality of the air and also have a check filter light. I love that I can customize my air quality since using this purifier I can breathe so much better it's quiet and it works for me and my household I notice that I have not been sneezing and rubbing nose from dust and cat hair, it  helps filter it out.  I recommend this product because I am really satisfied of how well it purifies the air it works.
