I absolutely love this air purifier and feel such a peace of mind now that I am using it! i love that it tells you the air quality percentage and has an auto setting that automatically turns on and off as needed. I also like that it has 3 different light settings to make it easier to understand the air quality. The air purifier it’s self is very quiet and I don’t even notice it running especially when the air quality is better it barely makes a sound! It’s very easy to use and understand and it also looks nice in the home! I also really like the touch screen design.
