The smart capabilities are great in "auto mode". When there's cooking smells in the air it turns up higher, as advertised. Low mode and sleep mode are very quiet. Don't know much about air purifiers but very happy with purchase so far.

Better than levoit ! Detects air quality as well and has auto mode!

Great product.

The purifier ramps up to high when we started cooking. The sensor actually detects poor air quality when I burnt some toast, and when cooking on the stove top.

I just got this delivered today. It came in the most perfect condition, the Bluetooth set up was very easy to use as well. The system is very quiet and doesn't make a lot of noise. I am very pleased with this purchase.
