This air purifier is A LOT larger than pictured. I initially requested this product thinking it would fit on my night stand. It arrived and I was surprised by how large it is. That being said, I love it! It is a smart device, so I can set a timer for it to run overnight on "sleep" mode. It creates nice white noise and works well. I haven't noticed a difference in the quality of the air yet, but I'm guessing that will be subtle and more obvious with time. It has 4 different modes: sleep, low, medium and high. I keep it in the bedroom and run it at night.

Pros: 
- easy to use
- sleek look
- quiet
- convenient settings

Cons:
- larger than advertised

Overall, very happy with the product and the functions!
