An island cooktop is the hardest appliance to place in an open kitchen, because the ceiling above it is usually where everyone expects a hood to hang. A downdraft cooktop solves that by moving the ventilation down into the appliance itself, which means no overhead hood, no dropped ceiling box, and sightlines that stay clear.
A downdraft cooktop is a built-in cooking surface with a ventilation fan and duct path built underneath it. Air is drawn in through slots at the front and back of the surface, pulled down through a plenum below the cooktop, and then either exhausted outdoors through ductwork or recirculated through a replaceable filter. That last choice matters more than any feature on the spec sheet, so we treat it in detail below.
We pulled together seven downdraft cooktops that actually exist as real products with real buyer feedback, then worked through size, wattage, airflow, cutout dimensions, clearance height, and what the reviews actually complain about. Every cooktop here is 220V or 240V hardwired, which is normal for a built-in surface and not a defect, but it does mean an electrician is part of the install for all of them. If you are still working out your island plan, our freestanding kitchen island picks are worth a look for the cabinetry side of the decision.

Do Downdraft Cooktops Actually Work?
Short answer: they handle steam, splatter, and everyday frying well, and they are weaker than an overhead hood on heavy sustained frying. That is the honest version, and it is the version most retailer pages leave out.
A downdraft pulls air straight down across the pan instead of pulling it up and away. That means the capture point is a few inches from your food instead of a foot or two above it, which is a genuine advantage for grease and steam. It also means anything you throw upward and backward can escape past the slots, and a downdraft cannot chase smoke that has already drifted to the ceiling.
The pattern that shows up repeatedly in homeowner discussions is telling. People who own hood-less island ranges report frying meatballs three or four times a year as the only moment they missed a vent, not as a daily failure. That matches how a downdraft is actually used: as the everyday cooking surface in an open plan, with a window cracked or a ceiling fan on the rare high-smoke night.
Forums also raise noise more often than performance. Owners with the blower relocated to a basement or lower level describe their systems as quiet, while owners with the blower in the cabinet directly under the cooktop describe them as loud. Appliance location does more for noise than any spec on this page.
One more caveat deserves space: gas. In-stove venting on a gas cooktop can pull the flame toward the vent slot, which cooks who stir-fry report as the biggest ongoing annoyance. Every cooktop in this roundup is electric, and induction among them, so flame pull is not a factor in these choices. It is the main reason gas downdraft models were harder to recommend here.
Downdraft Cooktop vs. Pop-Up Downdraft vs. Ceiling Downdraft
These three terms get used interchangeably in retail listings, and they describe three genuinely different appliances. Knowing the difference before you shop saves a wrong cutout and an expensive return.
Built-in downdraft cooktop
A downdraft cooktop has the vent permanently built into the cooking surface. It drops into a countertop cutout like any cooktop, the fan sits below it, and nothing moves when you turn it on. Every product in our roundup is this type. The trade-off is that the ventilation is fixed and cannot rise to chase smoke, and the plenum below the cooktop occupies cabinet space.
Pop-up downdraft riser
A pop-up downdraft is a separate unit that sits in a countertop slot and rises several inches out of the surface when you press a button, with the duct running down inside the island to a vent near the foundation as one forum commenter described it. The countertop stays flat when the riser is down, and the cost is a moving mechanism, a larger cutout, and an extra hole in your countertop.
Ceiling-mounted downdraft
A ceiling downdraft is a hidden hood dropped into the ceiling above the island, often behind a decorative panel or a retractable screen. Because the capture happens above the cooktop at roughly the height of an overhead hood, it captures the best of everything in this list, and it hides completely when not in use. It is also the most expensive to build, since you are constructing a ceiling box and hiding it inside finish work.
If you can hide a ceiling downdraft, that is the stronger ventilation option. If your ceiling is already built and you refuse a visible hood, the built-in cooktop is the practical answer, which is why that is what we rounded up.
1. Hobsir 30 Inch Electric Cooktop with Downdraft, 4 Burner 6000W
- Cooktop and downdraft in one appliance so no hood is needed
- 496 m3/h airflow with no exterior ductwork
- Dishwasher-safe removable filter for grease and condensation
- Frameless drop-in fit gives a flush integrated look
- Ductless recirculation collects condensation that needs regular cleaning
- 220V hardwired connection needs an electrician
- Lowest average rating in this group at 4.2
This is the one we keep coming back to, mostly because of what the review history proves. A 4.2 average sounds modest until you see that it is built on 186 ratings, the deepest buyer history of any cooktop we examined. When a rating holds steady across that many owners, it is telling you the product does what it claims rather than that nobody has had problems yet.
The mechanical case is straightforward: a 135W ductless motor moving up to 496 m3/h, four radiant elements sharing 6000W, and a dishwasher-safe removable filter. That combination means no exterior duct renovation, no roof penetration, and a filter you can rinse instead of replace. For a retrofit island where the cabinet below has no room for a plenum, that is the whole argument.
The radiant surface works with every pan material, which removes the single biggest objection to induction. Owners cooking on cast iron and stainless steel report no compatibility issues, and the touch panel gives nine power levels, a 99-minute timer, pause, and a child lock. Nothing here is exotic, and that is the appeal: it is a conventional cooktop with a fan built in.
The measurements are the part to slow down on. The unit measures 20.47 in D by 30.32 in W by 7.87 in H, and the cutout is 28.75 in W by 19.3 in D by 7.87 in H. That 7.87 in clearance requirement is the number that trips people up, because an existing island cabinet often does not have that much vertical room once a countertop is accounted for.
What works well about the hood-free fit?
The strongest positive is that it removes the hood decision entirely, freeing your island ceiling for pendant lighting instead of a ventilation box, and filter maintenance is cheap because the removable filter is dishwasher-safe rather than a recurring purchase.
What to watch before you order?
The 4.2 average is the honest weak point, with one-star reviews at 8% of the total and recurring threads about electrical install complexity and filter upkeep. Recirculating also means grease builds up where you cannot see it, and owners who ignore that for a year describe a cooking smell that only clears after a deep clean.
2. GTKZW 30 Inch Electric Cooktop with Downdraft, BBQ Bridge Burner, 360 CFM
- Cooktop and 360 CFM downdraft in one appliance
- Large bridge BBQ griddle and dual-ring burner
- 10 power levels from 140F to 518F
- Works with stainless
- cast iron
- ceramic
- glass and aluminum pans
- Heaviest cooktop in this group at 56.2 pounds
- 240V hardwired hookup required
- 15.75 in listed height means clearance must be checked
This is the pick for people who cook on more than four burner positions at once. The bridge BBQ zone merges two elements into a single wide griddle surface, and paired with the dual-ring burner it gives you a genuinely different set of shapes to work with. For someone who owns a cast iron griddle or cooks a full batch of pancakes, that flexibility is the reason to pick it.
The 360 CFM suction figure is the highest published number in this roundup among the units that state one at all, and it is a real measurement rather than a marketing estimate. Airflow matters here because capture at the source is the entire premise of a downdraft. More air moving through the same slots means better performance on the exact cooking this appliance is being chosen for.
Control granularity is unusually good for this class. Ten power levels spanning 140F to 518F is finer than most gas burners offer, and it makes low-and-slow work far more predictable. Buyers report using the pause function and the residual heat indicator more than they expected, both of which help when you are managing a bridge zone with a large pan on it.
Cookware compatibility is broad. Owners use stainless steel, cast iron, ceramic, glass, copper, and aluminum on the same surface, which removes the usual induction caveat entirely. Note that the listing specifies a tempered glass surface rather than ceramic glass, and that the burner data lists induction as the element type, so treat the element description with some care and confirm against the manual before ordering.
Why the cooking surface wins?
The cooking surface is the strength, not the vent. Between the bridge BBQ griddle and the dual-ring burner you get a layout that genuinely differs from a standard four-burner grid, 74% of reviews are five-star with owners naming the bridge zone first, and the child lock, timer, pause, and residual heat indicator form a complete safety set for an island where kids circulate.
Handling and clearance concerns
Weight is the practical problem. At 56.2 pounds this needs two people to lower into the counter, and the listed dimensions show 15.75 in in one axis against a 30.32 in by 20.47 in footprint, so measure the cabinet cavity rather than trusting the cutout number alone. One-star reviews run at 10% here, the second-highest share in the group, with install dimensions the dominant complaint.
3. Cooksir 30 Inch Electric Cooktop with Downdraft, Recirculating Air Vent
Cooksir 30 Inch Electric Cooktop with Downdraft, Recirculating Air Vent
- Ductless recirculating vent needs no exhaust pipe
- 7400W with dual-ring and 3900W bridge BBQ burners
- Documented over-temperature protection and auto shutoff
- Glass scraper included for the smooth top
- 220-240V hardwired installation by qualified personnel
- Flexible cutout range can be confusing to measure
- Some buyers say it lacks very high heat for demanding cooking
What separates this one is 7400W, the highest total cooking output of any 30-inch model in the roundup. Power like that matters on a radiant surface because radiant elements lose efficiency as they age and as pans lose contact. Starting with headroom means the surface still reaches temperature after two years of use.
The burner mix is interesting: a dual-ring element rated 1100W or 2300W, plus a 3900W bridge BBQ burner. That combination gives you a small-heat zone for a single egg and a wide high-heat zone for searing, controlled from the same touch panel. Owners praise heat-up speed specifically, which is what you would expect from a 240V circuit feeding that much wattage.
Documentation is better than most in this category, and that is not a throwaway detail. The manual includes cooking guidance alongside the safety-feature explanations, and the listing documents over-temperature protection, auto shutoff, and a hot-surface indicator as separate functions. When you are hardwiring an appliance into an island, knowing exactly what the protection system does is worth reading twice.
The ductless recirculating arrangement means no exhaust pipe at all, which is the simplest island install of anything we looked at. It also means the 135W motor handles the entire air path inside the unit, so capture depends on filter condition. Treat the filter the way you would treat an air filter: check it every few months.
Why the install is the easiest here?
This is the safest-feeling install of the 30-inch group. Recirculating removes the duct decision, the flexible cutout accepts a range of openings, and a 67% five-star share with zero one-star reviews points to few buyers regretting the purchase. The scratch-resistant smooth glass wipes clean, a razor blade and sponge strip are included, and it works with any flat-bottomed cookware.
Heat ceiling and cutout tolerance
The flexible cutout is a double-edged feature, because the manufacturer accepts any opening between the bottom and top glass dimensions. Get the cutout within spec before ordering since a misfit means a new countertop, and note that a minority of owners using it as a primary cooktop report it will not reach very high temperatures for demanding work.
4. ANHANE 30 Inch Induction Cooktop with Downdraft, 4 Burner 220V
30 Inch Induction Cooktop with Downdraft, 4 Burner 220V Electric Stove Top
- Induction surface with a true built-in downdraft vent
- 6600W across four zones
- Ten power levels for precise consistent control
- Child lock and over-temperature auto shutoff
- Induction requires magnetic cookware
- Deepest body in this group at 10.03 in so clearance needs checking
- No buyer reviews recorded yet on this listing
This is the only true induction surface in the roundup, and induction plus downdraft is an unusual combination worth explaining. Induction generates heat in the pan itself rather than the glass, which means the surface around a cooking zone stays cool. Less heat in the air above the cooktop is good news for a downdraft, because there is less rising thermal plume for the fan to chase.
Output is 6600W across four zones rated 1500W, 1800W, 1800W, and 1500W, controlled across 10 power levels from 140F to 518F. That temperature range specification is unusually honest for an induction listing, and it maps directly to real technique: low heat for a slow melt, high heat for a hard sear, both repeatable.
The safety package is thorough for an induction surface specifically. Auto shutoff, an over-temperature cutout, a residual heat indicator, a 99-minute timer, and a child lock all come standard. Induction already prevents the most common cooktop burn risk, and the added protections cover the edge cases.
Be aware of the physical envelope. The unit measures 19.68 in D by 30.31 in W by 10.03 in H, which is the deepest body height in this roundup. On an island where you planned to store pans under the cooktop, that height claim most of the cabinet, and it needs verifying against your actual cavity.
Best choice for induction cookware owners
For a cook who already owns induction-compatible pans, this is the cleanest cooking experience available in a downdraft format: no radiant element glowing under a pan, no heat lingering on the glass, and control that responds immediately rather than ramping.
Cookware and evidence gaps
The magnetic cookware requirement is a real barrier, since a kitchen stocked with aluminum, copper, or non-tight aluminum-clad pans means replacing cookware before the burner is ever turned on. There is also no recorded buyer feedback on this listing, so every reliability signal comes from the manufacturer specification rather than from people who own one.
5. Disaenvir 30 Inch Electric Cooktop with Ventless Downdraft Vent 7400W
- Highest average rating in this group at 4.7 with 79% five-star
- No exterior duct renovation needed at all
- 7400W with a 3900W BBQ zone and dual-ring burner
- Compact 7.87 in height preserves cabinet storage
- 240V direct wiring by an electrician required
- Measure your existing counter cutout before ordering
- Small review base of 33 ratings
The 4.7 average is the highest in this roundup, and unlike the 4.2 on our first pick, the distribution behind it is unusually clean: 79% five-star, 15% four-star, and zero one- or two-star reviews. That shape usually means the product matches its listing, with nobody reporting a failure mode.
Cooking performance matches the rating. 7400W total with a 3900W wide BBQ zone, a 1200W burner, and a right-side dual-ring burner switchable between 1100W and 2300W. Owners highlight fast heat-up, and that is a direct result of feeding that much wattage from a 240V circuit rather than a 220V one.
Where this one stands out from its 30-inch peers is physical. At 7.87 in tall and listed around 10 pounds, it is one of the slimmest bodies in the group, and it leaves usable storage space beneath where a ducted downdraft would put a plenum. On a small island where under-counter space is already tight, that height is a feature you feel every day.
The safety and control package matches: timer with auto shutoff, child lock, pause, and residual heat indication on a smooth touch glass panel that wipes clean. Owners mention the clear mounting and clearance diagrams as a positive, which suggests the documentation is doing real work during install.
Where power and slimness combine?
It is the least demanding install in the roundup relative to its cooking power: ductless recirculation, 240V hardwired, a standard 29.13 in by 19.3 in cutout, and a slim profile. Wattage and footprint work together well, giving you a full-size surface with a dedicated high-output zone in a body thin enough to drop into an existing island cabinet without a rebuild.
Thin evidence behind a high score
Thirty-three ratings is a thin evidence base for a 4.7 average, and high scores on small samples tend to regress as volume grows. The listing itself warns you to measure your existing counter cutout before ordering, recirculating performance depends entirely on filter condition, and you will need a 240V direct connection.
6. GASLAND Chef Collection 31.5 Inch Electric Downdraft Cooktop, 4 Burner
GASLAND CHEF COLLECTION 31.5″ Electric Downdraft Cooktop, 4 Burner, 220V
- Widest cooking surface in this roundup at 31.5 inches
- Up to 330 CFM with three-speed vent control
- Bridge element merges two zones for up to 4200W
- Removable grille and filter with a two-year warranty
- Heavy at 44.9 pounds so it takes two people to set
- Tall 9.6 in body requires real cabinet clearance
- Slide touch panel is harder to wipe clean than knobs
If your island was designed around a surface wider than 30 inches, this is the one that fits. At 31.5 inches it closes that awkward gap where a 30-inch cooktop leaves unusable counter beside it, and the extra width goes into cooking area rather than trim.
The vent control is the notable feature. Three speeds with up to 330 CFM of airflow gives you matched ventilation rather than a single on-or-off setting, so you can run low during simmering and high during searing. Owners single out the vent controls and the removable components as the practical standouts of the ownership experience.
The bridge element is the other reason to look closely. It combines two zones into one area delivering up to 4200W, which handles long pans, full-size griddles, and oversized cookware without fighting for space. Paired with a 7400W total across four radiant burners, that is genuine high-heat capacity on a residential island.
Maintenance is handled better than most. The vent grille, filter, and drip pan are all removable, so the parts that collect grease come out and get cleaned instead of being sealed into the appliance. Add a two-year warranty, the longest in this roundup, and a smooth ceramic glass surface, and it is a low-friction ownership story.
Why wide surfaces suit group cooking?
Adjustable ventilation speed is the differentiator versus every other 30-class unit here, all of which run a single ductless fan setting. Combined with the wide surface and a 4200W bridge zone, it is the strongest fit for someone cooking for a crowd on the island, backed by a two-year warranty and a 66% five-star share.
Weight and shallow-retrofit limits
At 44.9 pounds and 9.6 in tall it needs two people and a cabinet with genuine clearance, which makes it a poor fit for a shallow retrofit despite being the best cooking surface on the list. The slide touch panel is the small daily irritation to plan for, since owners note it collects grease and is harder to wipe clean than physical knobs.
7. Hobsir 36 Inch Electric Cooktop with Downdraft Extractor, 4 Burners 7400W
Hobsir 36 Inch Electric Cooktop with Downdraft Extractor, 4 Burners 7400W
- Widest cooktop in the roundup at 36 inches
- 3900W rectangular BBQ zone sized for griddles
- 496 m3/h airflow with no external vent pipe
- Detachable washable filter with a two-year warranty
- 240V hardwired install needs a licensed electrician
- Arrives without a plug so it can be mistaken for a portable model
- Smallest review base here at 24 ratings
A 36-inch cooktop changes what an island is for. With four zones plus a 3900W rectangular BBQ area measuring 16.9 in by 7.87 in, there is room for two pans going at once and a griddle alongside, which is a different cooking proposition from working across a single 30-inch surface.
The vent matches the ambition of the surface. The same 135W ductless system rated at up to 496 m3/h as the 30-inch Hobsir handles the wider cooking area, and the detachable washable filter traps grease and water so you can rinse it under a tap and pop it back in. That maintenance model is the reason we like this approach for a working kitchen.
Burner layout is unusually balanced: two 1600W zones, one 1200W zone, a dual-ring element switchable between 1100W and 2300W, and the wide BBQ rectangle. Total output is listed at 7535W. Zones accommodate pots from roughly 5.4 in to 9 in across, so you are not forced into a single pan size.
Owners report fast heat-up on 240V power and a modern sliding touch look that suits a frameless island. With 72% five-star ratings and zero one-star reviews at 4.6, the satisfaction signal is strong, and the two-year warranty is matched by responsive Hobsir service according to owners.
Why 36 inches changes the layout?
Surface area, plainly. For a large island where several people cook or where you want simultaneous pans plus a griddle, 36 inches is the difference between cramped and comfortable, and cookware compatibility runs across cast iron, stainless steel, ceramic, aluminum, copper, and glass.
Cutout and warranty fine print
The ductless approach means no exhaust pipe, so a 36-inch install does not require the duct run a 30-inch might get away with in some layouts. Controls cover nine power levels, a 99-minute timer, pause, and a child lock, and the detachable washable filter traps grease and water so you can rinse it under a tap.
How to Choose and Vent a Downdraft Cooktop for an Island?
Most disappointing downdraft outcomes come down to four things: airflow that was never strong enough, duct runs that were too long, clearance that did not fit, or a filter nobody maintains. Work through these before ordering anything.
1. Pick the fuel type before the brand
Gas, radiant electric, and induction each lose points in a downdraft application for different reasons. Gas works, but venting slots near the burners can pull the flame sideways, which cooks who stir-fry describe as the single biggest ongoing annoyance. Radiant electric is the most forgiving, works with every pan, and is what most of this roundup uses. Induction runs coolest around the zones, which helps capture, but requires magnetic cookware. If you cook with gas regularly, seriously consider a ceiling downdraft instead.
2. Match the size to the actual island
A 30-inch cooktop fits a standard 30-inch cabinet opening; a 31.5-inch or 36-inch surface needs a purpose-built island. Check the listed cutout, not just the cooktop width, since cutout dimensions run narrower than the glass on most frameless models. The 35.3 in cutout on the 36-inch Hobsir is the number to verify if your island countertop is already in place.
3. Check clearance height before anything else
Bodies in this roundup range from 7.87 in to 10.03 in tall. Anything above roughly 8 in eats into under-counter storage, and above 10 in it can rule out a shallow island entirely. Measure the cavity from the underside of the countertop to the cabinet floor, then subtract the thickness of any drawer slides or a reinforcing board.
4. Understand the airflow number and where the blower sits
Published figures in this category are inconsistent. Some listings quote CFM, others quote cubic meters per hour, and 496 m3/h converts to roughly 292 CFM. Neither figure tells you the whole story, because the rating assumes short ductwork. Forum owners consistently report better performance and lower noise when the blower is relocated to a basement or lower level rather than sitting in the cabinet directly below the cooktop. Long runs also bleed performance.
5. Choose vented outdoors or recirculating, deliberately
Recirculating models, which is everything in this roundup, filter air and return it to the room. They need no duct penetration, install faster, and cost nothing to run, but they handle steam and grease at the filter rather than removing it from the house. Vented models exhaust outdoors and are the right choice if you fry often or have an open plan where air moves between rooms. If you go ductless, budget for filter cleaning on a schedule rather than an afterthought.
6. Venting an island cooktop, step by step
Confirm the appliance spec sheet for the required circuit, breaker size, and cutout. Have the electrician run the 220V or 240V circuit to the island cabinet and leave a capped connection inside. Cut the countertop to the manufacturer’s cutout dimensions, keeping the glass supported at the edges. Lower the cooktop into the opening and secure it with the supplied brackets or clips. Connect the hardwired supply with the unit off at the breaker. If the model vents outdoors, connect the duct to the collar, seal every joint, and support the duct run at intervals so it does not sag or twist. If it recirculates, seat the filter and confirm the grille is clear. Test the fan on every speed before closing up the cabinet, then run the cooktop at full output while the vent runs to check airflow under real conditions.
7. Factor in the rest of the island before you order
The cooktop is one appliance in a furniture package. Seating, prep surface, and storage below all compete for the same space, and a tall body height reduces storage more than the appliance difference suggests. Planning the island alongside our kitchen island bar stool picks and microwave drawer picks keeps the whole island coherent. On whether a cooktop belongs in an island at all, the honest answer is that it works for most households who want the sightlines and poorly for anyone doing serious high-heat cooking several nights a week.
Frequently Asked Questions
What is a downdraft exhaust?
A downdraft exhaust is a ventilation system built into or beneath a cooking surface. Air is drawn in through slots at the front and back of the cooktop, pulled straight down through a plenum below it, and then either exhausted outdoors through ductwork or recirculated through a replaceable filter. A downdraft cooktop combines that system with the cooking surface in one built-in appliance, which lets you install a cooktop in a kitchen island without an overhead range hood.
Do island cooktops have to be vented?
Building codes in most jurisdictions require a mechanical exhaust for a cooktop, though the method is not prescribed the way a hood height is. In practice, an island cooktop is vented either through a ceiling-mounted downdraft, a pop-up downdraft riser ducted out near the foundation, or an integrated downdraft cooktop. Recirculating downdraft cooktops filter and return air to the room rather than exhausting it, which satisfies ventilation in some areas but not in others. Confirm with your local building department before finalizing an island plan.
How do you vent an island cooktop?
Run a 220V or 240V circuit to the island cabinet, cut the countertop to the manufacturer’s cutout size, drop the cooktop in and secure it, then connect the hardwired supply. For a ducted model, connect and seal the duct to the vent collar, support the run at intervals, and terminate it outdoors well above the roofline. For a recirculating model, seat the filter and leave the grille clear. Test every fan speed with the cooktop running at full output before closing the cabinet.
Can a downdraft cooktop replace a range hood?
For everyday cooking, yes. A downdraft handles steam, splatter, and most frying well, which is why hood-less island ranges are common in open plans. It is weaker than an overhead hood on heavy sustained frying because the capture point sits inches from the pan instead of above it, and smoke that rises past the vent slots will not be chased. If you fry several times a week and dislike the smell in adjacent rooms, a ceiling downdraft or a ducted pop-up riser is the stronger choice.
How loud is a downdraft cooktop?
It depends far more on blower placement than on the cooktop itself. Owners with the blower relocated to a basement or lower level describe their systems as quiet, while owners with the fan sitting in the cabinet directly below the cooktop describe them as loud. A 135W ductless motor in a small cabinet cavity is the worst case; the same motor ducted down to a larger plenum or a lower level is a different appliance acoustically. Ask about dBA figures where a manufacturer publishes them, and plan filter cleaning, since a clogged filter forces higher speeds.
Final Verdict for Downdraft Cooktops on Kitchen Islands in 2026
The best downdraft cooktops for kitchen islands are the ones that solve the hood problem without creating a second one. Our pick is the Hobsir 30 Inch Electric Cooktop with Downdraft, because 186 owner ratings is more real-world evidence than anything else in this roundup, and its 496 m3/h ductless system needs no duct renovation to work.
Pick the GTKZW if you want the most flexible cooking surface, the bridge BBQ zone and 360 CFM suction make it the better choice for volume cooking. Pick the Cooksir for the simplest install and the highest cooking output at 30 inches. Go wider with the GASLAND 31.5-inch for more surface and three-speed vent control, or the Hobsir 36-inch for a true multi-cook island.
Before you order anything, measure the cabinet cavity, confirm the cutout dimensions, and decide where the blower will actually live. That last question decides both performance and noise more than any feature on the box. And if you have already got a countertop cut in, measure twice, because that is the one mistake nobody enjoys fixing.
