Here's ours. The installation is pretty similar to your inspiration picture, a wood surround, using a custom Modern Aire liner.

Thank you all for posting the pictures -- it helps me visualize. The look definitely works for transitional or traditional cabinetry. I'm still trying to figure out if a modern look requires wider. Fouramblues, I asked my architect and GC a few times about whether our city has a MUA requirement. They both said they had never heard of one (and they both appear to be allergic to research). I tried researching myself online without any luck. We live in SoCal (no AC) and leave the kitchen window open most of the year for fresh air, so that is our MUA plan, lol. We also have a 50-year-old house that is not even close to air tight. Secondhalf, is that the Kobe RA-02-1? Are you satisfied with the finish? I was considering the 42" 1000 CFM version of that hood. I could only find 1 Kobe hood in a local store. It was a different model (pyramid with straight corner instead of beveled) and there was a visible seam all the way up the "corner" where the front panel overlapped the sides panel (i.e., the pyramid part was made with 3 pieces of metal instead of 1). Is that how your hood is constructed, or is the lower part seamless? Also, how much space do you have between your uppers and the hood? GreenDesigns, I thought I could offset size with higher CFMs. Would I be better off with a 42" 715 CFM hood? One hood in my budget that I find aesthetically pleasing (other than the mesh filters) is the Zephyr Venezia. I'm not sure I will ever use the grill on the range, as we grill outdoors year round. I only bought that model because it was a floor model at 35% off. If I had realized what venting my "bargain" range would cost, I would have skipped it. Now I wish I had bought induction, as it would have been cheaper to replace all my pots and pans if I could use a simple 600 CFM hood.

All hood filtering, whether meshes, baffles, or VAH sling designs, can only remove part of the grease aerosol particle spectrum. This part is that of the larger diameter particles, with decreasing performance through the mid-range. The rest is hoped to be discharged into the atmosphere, but there will be some collection in ducting depending on various factors. The only system I know of that can handle the entire spectrum is the intense UV approach used above commercial perforated ceiling collection designs. Hence, discharge into an attic not only subjects the attic to grease, water vapor, and odor, but could potentially be a fire hazard. Is there a reference somewhere in which VAH specifies that attic discharge is allowed? Earlier, the value 90 was raised. That may have been a misapplication of my expressed opinion on the flow rate (cfm) desirable per square foot of hood aperture to ensure that the 3 ft/s rising effluent from hot sources (griddles, woks, etc) is assured of containment by baffles and meshes. Rules of thumb such as cfm per BTU/hr or cfm per foot of hood edge are derived from various assumptions about the nature of the cooking field. kas

How many CFM do you need? What is your budget? A liner will definitely save you $$
