Product review (4 stars): Does the job quietly, but should really come with LED lamps.
The blower uses an efficient motor. Make sure your house has a vent externally, so it is properly exhausting the smoke. Otherwise, you'll be buying charcoal filters for this every few months.

My wife is Chinese and stir fries probably 15X per week. I bacon or sausage every weekend, so we needed a proper range hood, and this is it. It has a high CFM rating and also a low noise rating.

For less intense smoke, the low setting is VERY quiet; I can barely hear it. Going to medium and high really amps up the game, but it's not that quiet any more.

I have two complaints about this product:

1) It has an automatic mode, in which the fan stays on if it senses too much heat below it, or if it has absorbed more heat than it thinks is good. This cannot be overridden, except by unplugging it. Very annoying, when I'm done cooking and can't turn off the hood because it thinks it's smarter than me. What is it protecting me against?

2) It comes with halogen bulbs. Very hot-running and inefficient. I found a set of LEDs for it, but for a multi-hundred dollar range hood that probably only cost $10 to build, it should really come with cool and efficient LED lighting.

We saved the halogens as back-ups. An earlier reviewer put the part number for the LEDs I got.
