I got this air purifier because I needed a specific combo of features. I needed an air purifier that would deep clean the air when I needed it to, but would be silent when I needed it to. This purifier does both! The turbo mode really cleans the air quickly. I have this in my counseling office and they are doing construction on the floor below me so it has to really work to clean out the construction smells. But when I'm in session I switch it to silent mode and you can't hear a thing! It's perfect! I also love that it detects the air quality and auto adjusts. When I'm not in session I just leave it on auto mode and it keeps my office air clean.
The only time you hear it running is when it is on high and the only time it's on high is when the air quality is bad. I have two cats and when they scratch themselves you can see fine hair come off of them. The air purifier clears the air pretty fast. I'm very happy with this purchase.
I read a lot of great reviews of this product, and I honestly haven't noticed a big change in my rooms air quality. When walking back in from the outdoors I don't notice any difference in the air freshness. Aside from that, the machine is very quiet- however after several days of use my purifier started to make a low whining noise. I may have to contact customer service.
