Top 3 Best Downdraft Range Hoods (2025 Review)

As a licensed property inspector, I have seen a number of downdraft hoods over the years, but they are still pretty rare!

The best part about downdraft vents is that they take up minimal space, and sometimes they even rise up out of the countertop. Downdraft range hoods provide a compact and elegant way to exhaust cooking fumes from an island cooktop or kitchens with very tall ceilings.

Below is a quick list of the best downdraft vents. Keep scrolling to learn more about how to choose and use the best downdraft vent hoods.

What Is A Downdraft Vent?

A downdraft range hood is a type of kitchen exhaust appliance that is built into the cabinet either behind or to the side of the cooktop.

Most of these hoods have a motor which allows the range hood to rise up when it is needed, but some downdrafts stay flat and do not rise up. Their shape is usually rectangular and thin which helps with it's slim profile when it's turned on.

Downdraft hoods allow the cooking surface to be clear or flat when not in use which is their biggest advantage. Homeowners love downdraft range hoods especially for islands where an overhead range hood would obstruct the line of sight.

How Do Downdraft Hoods Work?

Downdraft range hoods are motorized and can rise up next to a cooktop anywhere from a low of 7-inches and all the way up to around 19-inches.

When a downdraft range hood is near the cooktop (rather than overhead), it pulls the fumes into a vent underneath the cabinet, and from there either to a side wall or under the floor to the outside through a metal duct.

Downdraft range hoods are generally in the range of 500-cfm to 750-cfm (fan speed).

Some downdraft range hoods can also be connected to remote controls so you can turn it on or off even when you are in another room.

Effectiveness

Downdraft range hoods can be highly effective at removing steam, odors, and grease from your kitchen.

The higher the downdraft vent rises up from the cooktop or range — the more effective it will be since it can suck in fumes at a higher angle. Also, the higher the CFM or fan speed of the downdraft vent, the greater it's effectiveness.

However, due to their design, they will never be equal in performance to overhead range hoods since it pulls in steam from the sides rather than overhead.

But for many homeowners the aesthetics of a downdraft vent are more important.

How To Pick The Best Downdraft Ventilation System?

Here are a few of the basic decisions to make when buying a downdraft venting system...

1. Verify Compatibility

Almost all downdraft range hoods are designed to be installed with self-contained cooktops (gas or electric) rather than slide-in ranges. The traditional installation of downdrafts is behind the cooktop, so there needs to be enough room in the cabinet for the hood, motor and ducting.

Slide-In Ovens

Most conventional slide-in ovens will simply not have the room to fit a downdraft vent along with the ductwork. However, homeowners may be able to install it to the side of the oven rather than the rear.

There are also a few downdraft vent models that have external blowers which may be able to work with a slide-in oven. The motor is installed in a different location such as in the basement or utility room which allows more room for the downdraft vent.

Homeowners should check with the manufacturer and verify there is space for an installation.

2. Consider The Ducting

Downdraft hoods typically have ducting that goes through the kitchen floor and into a crawlspace or unfinished basement and then to the outside. Homeowners may be able to install the duct through the rear or side of the cabinet and then to the outside — if the range is installed next to or near an exterior wall.

As an example, the Broan-NuTone Eclipse has three duct exit locations on the hood: the bottom, right-side, and left-side. The ducting should be kept as short as possible to the exterior and to minimize the number of bends.

It is essential to plan out the ducting and factor in any floor joist, wall stud, electrical or plumbing obstructions. We recommend carefully considering the ducting installation prior to the purchase.

3. CFM

The power of range hood downdraft vents is measured in CFM which stands for cubic feet per minute. CFM is a measurement of how much air the hood can exhaust in one minute.

There are several ways to estimate the needed CFM for a range hood, but the most common rule is to pick at least 100-CFM per linear foot of the cooking surface.

Alternatively, another guideline is 1-CFM per 100-BTU of total burner output for gas ranges.

4. Physical Dimensions

Homeowners need to verify that the downdraft vent will actually fit into the countertop space behind or to the side of the cooktop.

The downdraft hood should at least match the width of the range or cooktop. A hood that is less than the width won't be as effective at capturing steam, smoke, and grease.

And since the vent rises from the cooktop 7-14 inches, there shouldn't be any vertical obstructions. There also should be enough space at the rear for it to operate correctly, the Broan-NuTone Eclipse requires at least 2-inches of countertop BEHIND the vent.

Lastly, the cabinet and countertop itself should be at least 28-inches or more in order to have the room for the hood itself and the ducting underneath.

We recommend checking with the manufacturer for the physical requirements of the install or reading the installation manual.

5. Outlet

There needs to be an accessible outlet inside the cabinet for the downdraft hood. 

It is possible that there isn't room behind the downdraft for an outlet and it may need to be located on the side. Another option is to install an outlet on the exterior wall if it's just behind the cabinet — cutting out a hole in the cabinet for the cord.

How To Install A Telescopic Downdraft System?

Below are some of the basic steps to install a downdraft range hood. Please verify with the manufacturer's installation manual for your specific model.

1. Install Electrical Outlet If Needed: Downdraft vents need power through an outlet. If there isn't an outlet inside the cabinet, a new one will need to be installed. The hood can also be installed on a rear wall outlet with the cord going through a hole in the cabinet.
2. Cut Hole In Countertop: Use the provided template to mark out the hole for the downdraft unit and carefully cut it out.
3. Drop In Downdraft Vent: Carefully place the downdraft hood into the hole and fasten it in place with the provided screws. Shims may be needed for a straight fit and use any leveling brackets provided by the manufacturer.
4. Install Ductwork: Cut out a hole in the cabinet and floor or wall for the ducting (if it hasn't been done previously) and connect the ductwork. Make sure there isn't any plumbing, electrical, joist, or stud in the way of the duct.
5. Plug In Vent: Connect the power cord to the outlet inside the cabinet or on the wall.

Final Thoughts

Downdraft ventilation systems are a great alternative to bulky under cabinet, wall mount, or island range hoods.

These are also known as telescopic vent systems because a motor pushes the range hood above the countertop anywhere from a 5-15 inches.

It's essential to factor in the spacing requirements of the downdraft vent. Most of these systems are designed for electric or gas cooktops — and not slide-in ranges.

Another key component is the ducting installation. Most downdraft hood vents go INTO the floor and to the outside through a crawl space, basement, or garage.
