Received the Aaira Humidifier - I like the sleek design and it looks good in my bedroom.  I like that it has three fan speeds and that you can turn the blue light out when sleeping.  It operates quietly and I like that your can turn the timer on or just let it run.  It runs for a long time on just one tank of water.  I like that it removes the bacteria and viruses from the air you breathe. It generates hypochlorous acid (HOCl) to sterilize the air while incorporating a cold evaporation filter.  I also like that it has a humidity monitor to show how much humidity is in the air.  I like that it can just be used as a humidifier too.   It also has a two year warranty.  It is easy to set up and operate.
