Bought this one a few weeks ago. We have two gray Winix machines which look a little industrial. The LG is for the living room and has a nicer design. Overall, a great purchase even though a bit pricey.

I live in WA state, night now there are fires everywhere and the air quality is dangerous outside. It was 85 degrees in our 150sf bedroom and unbearable to sleep. I decided to open the window to cool it down. In 15 min the air quality on the purifier went from 15(good) to 150(really really bad). I shut the window once the temp was bearable and within 5-7 min the air quality was back to the teens. Amazing. This little machine was expensive, but worth every penny To be able to breathe.

I bought one purifier last fall and put it upstairs right outside our daughter's room. Last week, I bought a second one for our downstairs. This purifier cuts odors like nothing else I have ever had. The smell of fish and bacon is eliminated minute after you finish cooking. As someone who is sensitive to smells, this is really important to me. In addition, I have really bad seasonal allergies and this purifier has made my home an allergy-free zone, which is huge! I bought a third purifier to gift to my brother who lives in Santa Barbara, CA. This was at the height of the scare with forest fires and he had been issued a mandatory evacuation notice a couple times because of forest fires. Needless to say, this meant his apartment and everything he owned was permeated with the smoke. My brother said that the smell of smoke was gone after running this purifier for a couple hours!
