Product review (5 stars): This range hood works great. No more cooking odors.
I was at first skeptical to buy this range hood due to the following reasons:
1) This model looks different from other regular range hoods with baffle filters.
2) The range hood depth may not be enough to capture all the smokes and smells.
3) I was not sure how well the self-cleaning will work by just squirting a cleaning liquid into the fan as shown on Zephyrs website
4) I wasn't sure if its too cumbersome to unscrew the  grilles for cleaning

I did tons of research and finally bit the bullet and purchased this range hood. I had a professional to install this hood along with the Broan 8 universal make up air damper kit. Its been a month and Im really very happy with this range hood. I cook a lot of Asian and Indian food and this hood is able remove all the cooking smell, smoke and grease. I no longer have to close the bedroom doors or open the patio doors when I cook.

I tried the self-cleaning method and it works like a charm. Unscrewing the grill is a breeze and cleaning the grilles are very easy. I placed them in the dishwasher and there are no discolorations. I ran the hood in Q  Quiet mode and squirted 409 cleaning liquid around 35 times in each blower as per the recommendation. The detergent liquids were collected in the grease cups and they were brown in color. I did not feel any greasy / oily residue inside the blower fan (I tried this after switching off the hood).

This range hood is not very loud in the highest settings. Make sure to use either 8 or 10 galvanized steel duct. If you use less than 8 duct size then the hood will sound like a jet and may not function properly. I used the 8" Zephyr wall cap outlet with screen and damper (AK00044). I'm not disappointed this this range hood.
