Excellent air purifier, as long as it works very well, the noise is very small. On the second day of use, my husband said the air in our room was fresher. The effect is obvious, it's great. We also drove it at night after we went to bed, yes it doesn't wake us up, which suits me very well. In conclusion, I would like to say that this air purifier is good value for money and I would highly recommend it.
