175 CFM is not much. You really want 600 CFM. Microhoods are notorious for not being very effective - low CFMs and small capture area. If you're venting outside, you're much better off going with a 600 CFM hood.

i would tell you to spend a few extra dollars, buy a cheapo microwave for the counter or pur a nicer one in a cabinet and get a decent 20" or deeper hood. I think 600cfm is more than you need for the range but more is never a bad thing...if you see 450-500cfm at a resonabl price thatll do the trick

id say to look at zephyr or the rangemaster broan to decent priced powerful hoods

I recently replaced my older OTR wirlpool, which had to have been around 175 CFM at the most, this thing was horrible. I was torn between having an OTR microhood or not. I ended up going with a LG OTR microhood. It is 300 or 330 CFM and works SOOO much better than the other one I had. It has a 5 speed vent setting which is very nice. Typically I have it on the highest setting for stir fry or pasta and level three for most everything else. Now, I have it over an electric bosch slide in, so I feel its sufficient, but if you have one of the high btu gas ranges, you may need quite a bit more than that.

Thanks! I will look into an LG. What about the noise? Listening to this 400 cfm unit I can't imagine putting up with that.
