Product review (5 stars): I'm a FAN
I did a lot of research on this. Compared all pros and cons with much more expensive models. I don't cook that much since we retired. Designed new kitchen and wanted good ventilation. This unit recirculates and cleans air in room.  I could not have one which is tied to my duct work. This unit is beautiful and had a great presence in my almost professional look all white kitchen. The fan has three levels and even the top speed is not very loud. There are 4 lights located in the four corners. Very bright!  You can also program the time.  I would suggest this to anyone.
