This is a great air purifier from Levoit. Easy to set up (just remove the plastic and insert the filter) and easy connect to the app or can use the menu on the top to control as wel. This is quality solid construction and a decent size that isn't too big can even put it on a counter or table. Noise is compatible with other purifiers of this size and isn't too bad especially on the lower settings. I love the technology on this that it uses laser air quality censors and it moves a nice amount of air through while cleaning the room. You will see a difference in air quality after using this unlike some other air purifiers. Overall a great product
