I need low profile hood for Bluestar RCS no taller than 6'' and rated for 6'' ducting. Don't have much space to work with as the cabinet it will be mounted under is very low, so I cannot get anything higher than 6''. I have tall cabinet over it, so the motor can be pretty big in cabinet as there's space, just the actuall hood cannot be high. Also the ducting is 6'' and I have no way of changing it to bigger. Thanks.

I did end up purchasing the Kitchenaid Low Profile microwave. I originally wanted the Zephyr Typhoon 30" Stainless Steel Quiet Under-Cabinet Range Wall Hood AK2100BS. I could have done without a microwave (I never use it) but another family member uses one daily and we have limited counter space to accommodate a microwave on the counter. I like the KitchenAid Low Profile microwave very much. It is very stylish and streamlined, creating a much less bulky appearance than our former standard size OTR microwave. There is a two setting option for the lights and they are very bright. There is a four speed fan and it is somewhat noisy on the highest speed, which I expected. The fan does a fairly good job at removing smoke / odors and I can actually see the cooking smoke / fumes going upwards into the exhaust fan but I still do smell some small residual cooking odors in the home. We have outside venting. I don't do wok cooking or anything extreme so it works for my needs at this time. If I can answer any further questions regarding this item, please let me know.

FWIW. I have a 600 CFM Vent-a-Hood 42", regular depth and passive make up air, for a 36" induction cooktop. It collects everything. However, I believe it would be not enough if it was a short depth as I can see the entire hood filling up. It certainly wouldn't be enough for any kind of gas cooking appliance with all those poisonous fumes.

@wdccruise Thanks! I went out to look at them in real life. I had considered the Samsung--I like the door latch and the controls. However I think I'm actually going to go with this Whirlpool one even though it has the controls on the inside, which seems crazy. https://www.appliancesconnection.com/whirlpool-wml55011hs.html The +30 second button is on the outside, which is what I use 95% of the time. The door is about 6" shorter--I didn't realize at first because it's shorter from both ends. And it's not quite as deep as others--an inch less than some others. All these things help with the face-whacking issue. As for the fan, this one does have 400 cfm, but I almost never use the fan. I should, as we have a gas range. But I rarely cook anything splattery and we're switching to induction, so won't have the indoor air pollution. And it doesn't vent outside. We were going to vent outside as part of the renovation, but since we really use it so rarely, husband (who was the one who wanted it to vent outside in the first place) decided he'd rather not put a hole in the house.
