This range hood has made a vast improvement in our house allowing all of the fumes from good Chinese cooking to be vented outside. Now, when my wife returns home she can smell dinner on the way up the driveway. Even on low setting it sucks up most everything. There are 4 levels for the fan and I have not had to go above 2 in order to vent all fumes off the range. Also, we are surprised that it is as quiet as it is. That is not to say it is quiet, but we were expecting it to be louder, so are quite happy with the current sound levels.
