Works really well. The pre filter captures so much dust you can really tell it's working as it should. The screen shows how dirty the air is and you can watch it go down as it cleans, didn't think we would need that but it's been surprisingly satisfying to see the quality visually. Very quiet on the lowest setting, easy to sleep with.. gives a nice white noise. The highest still isn't bad, the volume is similar to like a normal tower fan. Design is nice, it's a good looking machine. The only negative would be how bright the small display screen is at night but we just cover it if needed. Haven't tried the oil extract diffuser and probably won't. Works very well for cigarette smell! I'm sure if we had two it would completely remove the smoke smell. Overall would definitely buy again.

Sound not an issue

Color: White

I've had this for about a month, so far works great. I smoke Cigars in my apartment and it is working good. Clears the smoke great even with the filter it came within is a bit loud on the 2nd and third setting, but it is not distracting. I leave it on the first setting over night and its quiet. Next morning there is no cigar smell. Of course I empty ash try. When I come home from work my place smells great and I hardly see see any dust on my glass TV stand and tables. I've read some bad reviews on the sound, but its something you don't hear when tv or radio is on. It really sounds like having a fan on. I would recommend this for the price. I've had other air purifiers no difference on sound.
