Range hood has a two-stage 200 CFM fan
Microwave (I am looking at GE Profile XL1800) has three stage + booster 300 CFM fan. However, microwave duct has several elbows which decreases vent efficiency, and range hood pretty much blows straight out.
I have heard an opinion that over-the-range microwaves are not as good in terms of venting comparing to the range hoods.
Any opinions on that?
