Compared to other air filters I have used in the last, this one is far superior. I love that the filter has a colored sensor to alert you if the air quality in the room gets worse. Even on the highest setting (3), the fan is still not so loud that it causes an issue. I also love that there is a nighttime mode (so it’s super quiet and the light turns off. I’ve noticed a major difference in the way dust and pet dander seem to irritate me way less since using this air filter.
