Product review (3 stars): not too great with non-ducted installation
the product looks great and is well built. I don't have a duct leading outside the house so i followed the instructions to recirculate the air into the kitchen. Installation wasn't too bad but not easy (one of the four screws needs a very long(8"+) screw driver to reach into, it is in the corner so it is essential to install, expect to scratch your hands reaching it), our kitchen cabinet had issues and i had to custom cut a thin sheet of plywood.... one major issue i have now is the noise, on 'high' setting it becomes unbarable, the air rushing out of the vent and into our kitchen area generates high noise, i put a short piece of scotch tape covering a small part of the duct to make it less noisy. And don't expect that no matter what you cook it will be sucked in, the cfm rating is high but the squirrel cage is on the left side not in the center, so you have to cook under it to have better results(but it is never as you want it, which is watching everything sucked in with force into the filters). Also, if you install it without a duct don't expect to eliminate the food smell in the house as you are recirculating the air, only moist and some particles would stick in the filters (which is important), but the smell will still be there....

this is my experience with non-ducted installation, i am assuming all hoods have the same issue and maybe this is the best out there. We had to put something in that space and this hood fits great with our stainless steel appliances.
