Yes, I too would like to see the link. Also, I am confused by your post. Your post sounded like you do not have a downdraft now. If that is the case, then whether you install a downdraft exhaust or a (much better) ceiling exhaust, you will still have "to install a new vent system". If you have to install new ducting no matter what, it will be so much more effective to install an overhead vent. Keep in mind that smoke and grease rise up, so that a downdraft is fighting the laws of physics. You will also have to make sure you have the space in your island front-to-back for the induction range plus the downdraft.

Thanks for the response. This is my first time posting here and I am not sure what you mean by "a link". I have cc'ed a photo of the overhead vent that we saw at ikea.

Regarding our current resources, we do have a downdraft vent system in place. My two worries are in fact

1)Will an induction oven and a telescopic downdraft fit in a standard 24 inch cabinet? Any suggestions for a model?

2) Is a telescopic downdraft sufficient for an induction cooktop? Would the ceiling-mounted extractor hood (which I think filters and then recirculates the air) be better?

Thanks so much!

I don't know what you mean by "cc'ing". When you post a message, you will see underneath the posting box several icons like "B" for bold, "I" for italics. The last icon on the right says "Link". Click on that, and when the link box pops up, copy and paste the website address for the Ikea extractor hood your are talking about.

If you want to post a photo, click on the icon below the message box that says "Photo" and paste your photo.

Here is a link to all the "extractor hoods" on the Ikea website:

Got it! I am trying again.

OBEROENDE Ceiling-mounted extractor hood

Afarzin - when you are talking about a "24" cabinet", do you mean front-to-back or side-to-side? When you say "oven", do you mean "range"? (a range is a cooktop and oven combined in one appliance).

Re the Oberoende hood you linked - I am not a fan of hoods with glass, because they show every splatter. Even though you think a glass hood will look "lighter", if you have to be cleaning it all the time, or looking at last night's splatter on it, the lighter look won't matter. I'll also link this one at Costco which can either exhaust to the outside, or recirculate - it does not have glass, and a pyramid shape is more effective than a flat shape:

Re the question of whether a downdraft exhaust that exhausts to the outside is better/worse than a ceiling hood that just recirculates: it kills me to say it, but I guess the downdraft is better of those 2 Evils. It's always better to have the smoke and grease exit to the outside. I just do not like downdraft exhausts compared to overhead exhausts, because as I said, they go against the laws of physics - smoke and grease travel upward, not sideways and down. Have you explored the idea of exhausting an overhead hood to the outside? Depending on your setup, it may not be that difficult or too expensive. It just depends on what your house is like.

If you decide on a downdraft, look for the telescoping model that pops up the highest. Look for 12" to 14" telescoping height. Prices range from $1000-2000. I've seen Thermador downdrafts recommended on this forum. Thermador Downdraft

Thanks so much for the advice! I was wondering if anyone has experience with fitting an induction oven and a telescoping downdraft in a standard 24 inch island.

>>>"1) Will an induction oven and a telescopic downdraft fit in a standard 24 inch cabinet? Any suggestions for a model?<<<

No. In the North American appliance market, there is no such thing as an induction range that will fit in a standard 24-inch (wide) base cabinet, much less one that will accommodate a telecoping downdraft in that space. (You did mean 24" wide and not 24" deep, i.e., counterdepth?)

For what you seem to want, you might be able to combine a 24" induction cooktop with a small wall oven beneath it, but, AFAIK, all the telescoping (pop-up) downdraft systems are 30" wide or larger.

Recirculating/Ductless overhead units vary in quality, ability and expense. Effectiveness depends on the size and filtering system. A recent DOE-labs study on venting called many of the inexpensive models "forehead greasers." Some gardenwebbers have found workable "ductless" models, although those models tend to be expensive. Here's a link to a thread on one of the Ikea models:

The overhead recirculating system that has garnered to the most positive reports here is the expensive Vent-a-Hood "ARS" system.

Ranges don't work with downdrafts, period. And downdrafts don't really ''work'' either. The difference is night and day between a proper 0verhead ventilation system and the struggles against physics to force cooking byproducts to act against mother nature.

A cooktop takes less depth than a slide-in range. That could allow space for a downdraft. An oven below and you're done. The price of separates can be more.

Thanks so much! I actually meant to say "induction cooktop" and not induction range. Any suggestions for an induction cooktop/downdraft that will fit into 24 inch depth?

Okay, we're talking standard width induction cooktops (i.e., 30 or 36 inches wide) with a standard depth base cabinet and fitting a telescoping vent behind the cooktop?

IIRC, GE and Wolf induction cooktops require the smallest cut-outs. Can you fit a telescoping vent behind them? Maybe. Depends on how your island and its countertops are set-up

I suggest you go to vendor websites like AJ Madison to find cooktop and downdraft cut-out dimensions and installation instructions. Remember that both cut-outs have to fit within the walls of a standard base cabinet. (Depending on what the cabinet is made from, the open space in a base cabinet will be, front to back, between 22½" to 23" deep.) Don't forget that the back edge of the cooktop is a lip that extends anywhere from one-half inch to an inch back from the rear of the cooktop's cutout. Reading the install instructions for the various telescoping downdrafts will tell you if you can fit one in behind a new cooktop.
