I am so happy I got the Sciaire Mini Air Purifier. After using it for about a month I have felt like the air in my home is a lot cleaner. I am very allergic to pollen and dust and I feel like I have been able to breath better since using this. I really like that it shows how clean your air is by color so there is no guessing. I really like the sleep mode, because it does become very quiet and you can barely tell that it is on. It is bigger than I was expecting but it looks nice and is sleek.
