This air purifier not only works very well, but it’s also sleek and cool looking. I have major dust issues with the apartment I live in. I can dust my furniture only to l have it reappear after only a couple of days. this purifier has helped with that tremendously. It has cut down my dusting to a week to two weeks now. It has a sleep mode. That’s extra quiet, but I actually use that during the day when I leave to work. I like to set it to the third fan setting at bedtime because I like the white noise. The soft glow at night is a big plus. My entire room just now smells and feels fresher. I’m thrilled with this unit.
