How the Five Compare on the Numbers
Four of these five publish an airflow figure, and they are not describing the same kind of product. Sakura states up to 1200 CFM from dual DC motors with a turbo switch. ZLINE publishes its whole curve, 480, 560, 650 and 700 CFM across four speeds. Broan’s retractable downdraft uses a 500 CFM internal blower. OVO states 225 CFM. GLENCREAG publishes 2600 to 4600 RPM instead.
Weight sorts them into two groups. ZLINE is the heaviest of the five at 50 pounds. Sakura is 42.3 pounds, which is what a steel shell with baffle filters comes to. OVO publishes 9.04 pounds and gives 29.9 by 17.5 by 4.7 inches without saying which figure is which. Broan lists 8 pounds for a 30 inch downdraft with an internal blower, which is hard to believe.
What the table cannot tell you is whether any of these figures were arrived at the same way. A CFM number quoted at a top speed says nothing about the setting you will actually run, and only ZLINE publishes the steps in between. No listing gives a duct diameter, so none of them can be matched to ductwork you already have. No listing states its sound level at the airflow it advertises.
Airflow Figures That Do Not Line Up
What the CFM Numbers Here Describe
ZLINE is the only listing that treats airflow as a range rather than a headline. It publishes 480, 560, 650 and 700 CFM against four push button speeds, and names 700 CFM as the highest setting rather than the working one. That is more useful than a single figure, because the speed you leave it on is the speed that decides both the noise and the extraction you actually get.
Sakura goes about it differently. The 1200 CFM figure is tied to a turbo switch sitting on top of three ordinary speeds, and the listing frames turbo as a stir frying tool rather than a default. It is a larger number than anything else on this page, and it arrives with two DC motors and a touchscreen, but the listing never says what the three lower speeds deliver.
Where the Figure Is Missing or Contradicted
GLENCREAG publishes 2600 to 4600 RPM across three speeds and no airflow figure anywhere. Motor speed and air volume are different quantities, and nothing in the listing relates them, so this unit cannot be placed on the same scale as the other four. Its size field says Standard, which is not a measurement either, and its published figures are 6.3 by 8.3 by 12.6 inches.
OVO has the opposite problem, a figure that its own listing contradicts. The title sells a two speed exhaust fan at 225 CFM, and a feature bullet on the same listing says three speed electronic controls. Both statements come from the same maker on the same page, so the number of speeds is unresolved and the 225 CFM cannot be pinned to any particular setting.
Three Mounting Types Under One Search Term
The Under Cabinet Trio
ZLINE, Sakura and OVO are the three that go under a cabinet, and they are the only three that compare directly. All three are described as 30 inch units, ZLINE in its size field, Sakura and OVO in their titles. ZLINE ducts from the top, OVO offers a rocker switch and a carbon filter for ductless running, and Sakura publishes neither a duct position nor a ductless mode.
Their published dimension fields then disagree in a way the listings never resolve. ZLINE gives 24 by 30 by 18 inches, Sakura 30 by 22.4 by 9, OVO 29.9 by 17.5 by 4.7. Every one of the three calls itself a 30 inch hood, yet in ZLINE’s case the 30 sits in the second field rather than the first, so the field labels cannot be trusted on their own.
A Downdraft and a Countertop Fan
Broan is not an overhead hood at all. It is a retractable downdraft with a 500 CFM internal blower, sold for kitchen islands and peninsula countertops, with an infinitely adjustable speed control set flush into the side of the unit. It is also the only listing in the group that names its ductwork shape, rectangular, and says the run can be installed horizontal or vertical.
GLENCREAG sits further out still. It is a portable desktop unit for indoor barbecue, hot pot, tabletop grilling and RV cooking, with a face that pivots from 30 to 180 degrees and no drilling or tools required. It is in this pool only because its own title uses the words range hood. If you are replacing a fitted hood it is the wrong tool, and it is named here so the mismatch is visible.
Filters, Ductless Running and Noise
What Catches the Grease
ZLINE and Sakura both use stainless steel baffle filters and both say they are dishwasher safe. Sakura adds that its filters detach and calls them heavy duty. A baffle is a permanent part, so on these two the upkeep of filtration is a dishwasher cycle rather than a replacement. Broan publishes nothing whatsoever about filtration, which is the one real hole in an otherwise detailed listing.
The other two lean on consumables in different ways. GLENCREAG lets you choose a reusable aluminum mesh filter or disposable pads, released by pressing a ring at the top. OVO includes its carbon filter for ductless running. ZLINE’s ductless mode needs charcoal filters, model RK, and the listing says plainly that they are not included, which turns recirculating into a second purchase.
The Noise Figures, and the Three With None
Sakura is the only listing that publishes noise in two units. It gives 1.5 to 5 sone across its range and 42 dB at the lowest setting, and describes an air exchange function with a three step timer that it calls extremely quiet. Those figures sit on the same listing as the 1200 CFM claim, and nothing connects the quiet number to the loud setting.
GLENCREAG states operation under 60 dB and adds that lower speeds suit conversation while higher speeds move more air, which is at least an honest trade off. ZLINE, Broan and OVO publish no noise figure in any unit at all. Three of the five saying nothing about sound means noise can separate two products here and not the group.
Which One Fits Your Kitchen
Heavy wok and stir fry cooking. Sakura is the one with a turbo switch quoted at 1200 CFM, dual DC motors, detachable dishwasher safe baffle filters, and the only noise figures on this page, 42 dB at its lowest setting and 1.5 to 5 sone across the range.
Replacing a worn under cabinet hood. ZLINE publishes the full fan curve, 480 to 700 CFM over four speeds, ducts from the top and converts to ductless if you buy the charcoal filters separately. At 50 pounds it is also the heaviest here, so check the cabinet it hangs from.
A renter who is not allowed to drill. OVO includes the carbon filter instead of selling it apart, states 225 CFM, and uses a rocker switch meant to work with oily or wet hands. Its two LED pucks are published at 2 watts each and 4000K, which is the only lighting figure here.
An island cooktop with nothing above it. Broan is the retractable downdraft, a 500 CFM internal blower, rectangular ductwork that can run horizontal or vertical, an infinitely adjustable speed control, and the only warranty stated anywhere in this group, one year limited.
Hot pot, indoor grilling and RV galleys. GLENCREAG is a countertop fan rather than a hood. Three speeds from 2600 to 4600 RPM, a face that pivots from 30 to 180 degrees, mesh or disposable pad filters, under 60 dB, and nothing at all to install.
What We Could Not Verify
Six things a buyer would reasonably want from these five listings and cannot get from them.
- Broan publishes 8 pounds for a 30 inch downdraft with an internal 500 CFM blower. That is not a plausible figure for the product described, so no weight comparison on this page rests on it.
- No listing publishes a duct diameter or a duct collar size, so none of these five can be matched to ductwork that is already in the wall or ceiling.
- Sakura’s 1200 CFM and its 42 dB figure are stated separately, and nothing says the quiet figure still applies at any speed above the lowest one.
- OVO’s title says two fan speeds while its own feature list says three, and the listing offers nothing that settles which is right.
- GLENCREAG publishes only 2600 to 4600 RPM, which cannot be converted to airflow, and the bullet explaining what it is not intended for is cut off mid sentence.
- Only Broan states a warranty. No listing anywhere in the group states a filter replacement interval, an expected motor life, or a sound level at the airflow it advertises.
