I bought this air purifier on Amazon a few months ago and I love it. I have horrible allergies and this purifies the air so I can breathe. The colors cycle through and you can press the button to stop on a specific color or press and hold the button to turn off all lights. When the lights are off and the fan is on setting 1 you will never know this thing is on. But it is STILL WORKING HARD! I loved this air purifier so much I just bought another one for another room in my house. It may not be name brand but I can't recommend this enough.
