If you’re looking to improve kitchen ventilation, upgrading to a range hood is a smart move. While over-the-range microwaves combine cooking and venting in one unit, range hoods typically deliver stronger airflow thanks to higher CFM (cubic feet per minute) ratings. Whether you choose a ducted or ductless model, a range hood is a valuable upgrade, especially if you're replacing an existing microwave vent. Keep reading to find out how to safely and effectively swap your over-the-range microwave for a dedicated range hood.
What Are My Kitchen Ventilation Options?
There are many different types of kitchen ventilation systems to consider. One popular option is the over-the-range microwave with a built-in vent. However, before deciding between an OTR microwave and other types of range hoods, it’s important to understand all the choices available to you.
Use the categories below to explore the full range of kitchen ventilation solutions, including ducted and ductless range hoods.
Canopy Range Hoods
Canopy hoods come in both wall-mounted and island-mounted models. These hoods offer powerful ventilation and often include advanced features, making them ideal for open kitchens and frequent cooking.
Under-Cabinet Range Hoods
Under-cabinet range hoods are compact and space-saving. They are installed beneath the cabinet above the cooktop. Despite their smaller size, they vary widely in ventilation power and filtration capabilities.
Over-the-Range Microwave Hood Combos
These appliances combine a microwave oven with a built-in ventilation fan. They help remove smoke, grease, and odors while saving space by replacing a traditional hood.
Downdraft Range Hoods
Downdraft hoods are installed into the countertop and stay flush when not in use. They rise up when needed to pull cooking fumes downward, making them ideal for minimalist or island-style kitchens.
Portable Range Hoods
Portable range hoods, like the Ciarra Hood To Go, are a flexible and convenient option for renters, small apartments, or temporary setups. These ductless units use activated carbon filters to capture smoke and odors and can be placed anywhere without installation. Lightweight and rechargeable, they’re perfect for indoor grilling, small stovetops, or RV kitchens.
What Is the Standard Range Hood?
The standard range hood is a dedicated appliance installed above the cooktop or range. Its main job is to ventilate your kitchen by removing airborne grease, smoke, heat, and odors. Range hoods come in various styles, including wall-mounted, under-cabinet, island, and ductless options.
What Are The Benefits Of A Range Hood VS. A Microwave Vent?
Compared to over-the-range microwaves, a dedicated range hood offers significant advantages in ventilation performance. When deciding between a range hood and a microwave vent combo, your choice often depends on how much ventilation power you need and the layout of your kitchen.
If your kitchen has enough space or you don’t require the dual functionality of a microwave with ventilation, a standalone range hood can offer the following benefits:
Stronger Exhaust Power
Range hoods generally deliver higher CFM (cubic feet per minute), making them much more effective at removing smoke, grease, and odors from the air.
Flexible Venting Options
Many range hoods offer both ducted and ductless configurations, allowing for more customized installation based on your kitchen's structure.
More Stylish Options
Range hoods come in a variety of designs, including stainless steel, glass, or built-in styles, making them a visual highlight in modern kitchens.
Heat Resistance
Range hoods are built to handle the high heat and intense steam produced during heavy cooking, unlike many microwave vent systems.
Advanced Features
Many range hoods now include smart touch controls, timers, LED lighting, and even air purification technology.
Advanced Ventilation Features
High-end range hoods often include perimeter suction (perimeter ventilation), multi-speed fan settings, quiet operation, and efficient grease filtration — all designed for a healthier and cleaner cooking environment.
In short, if powerful performance and long-term durability are your priorities, a range hood is a better choice over a microwave vent, especially in larger or high-traffic kitchens.
Are Microwave Range Hoods Ductless?
Yes, most microwave range hoods — also known as over-the-range (OTR) microwaves — are ductless by default, but many models are designed to be convertible. That means they can be installed as either ductless or ducted, depending on your kitchen setup.
While most microwave range hoods are ductless out of the box, many are convertible and can be ducted if your kitchen allows it.
Should I Choose a Microwave Range Hood or a Range Hood?
The answer depends on your kitchen layout, cooking habits, and priorities, but in most cases, a standard range hood is the better choice, especially if you cook often or want better ventilation performance.
Choose a Range Hood if:
- You want stronger ventilation power to remove smoke, steam, and grease effectively.
- You cook frequently, especially with high heat (e.g., frying, searing, boiling).
- You value better air quality and cleaner kitchen surfaces.
- You prefer more design options, like wall-mounted, under-cabinet, or island hoods.
- You’re looking for long-term performance and durability.
Choose a Microwave Range Hood if:
- You’re tight on space and want a 2-in-1 appliance that saves counter space.
- You don’t cook often or only prepare simple meals.
- You're looking for a budget-friendly solution.
- You live in a rental and want minimal changes.
If you need a space-saving solution but still want better ventilation than a microwave vent provides, consider:
- An under-cabinet range hood (compact but powerful)
- A portable range hood like the Ciarra Hood To Go, perfect for small kitchens, dorms, or rentals
What are The Limits of Over-the-Range Microwave Vents?
While over-the-range (OTR) microwaves offer the convenience of combining two appliances in one, they come with notable drawbacks when it comes to ventilation.
Common Downsides of Microwave Range Hoods:
- Weaker suction power, typically around 150–300 CFM
- Poor smoke and grease capture, especially during high-heat cooking
- Awkward height for microwave access, especially for children or shorter users
- Limited design flexibility — they often look bulky and outdated
How to Replace an Over-the-Range Microwave with a Standard Range Hood
If you're ready to upgrade your kitchen ventilation, removing an over-the-range (OTR) microwave and replacing it with a standard range hood is a great choice. While microwave hoods offer convenience, a dedicated range hood provides better airflow, more powerful smoke removal, and a sleeker design.
This project can be completed as a DIY task, but it does require two people and some basic tools. Below is a full overview of how to remove your OTR microwave and install a standard wall-mounted range hood.
Tools You’ll Need
- Power drill or screwdriver
- Socket wrench (if applicable)
- Towel (to protect surfaces)
- Stud finder
- Tape measure
- Wire stripper and cutter
- Caulking gun
- Oscillating tool or reciprocating saw
- Level
- Ducting materials (metal duct, aluminum tape)
- Electrical connectors & wires
- Wall or cabinet mounting screws
- Range hood mounting template (usually included)
Part 1: How to Remove an Over-the-Range Microwave
This step requires two people — one to support the microwave while the other removes the mounting hardware.
Step 1: Clear the Upper Cabinet
Open and empty the cabinet above your microwave. This is where the power outlet and, if applicable, the vent connection are located.
Step 2: Disconnect the Vent (If Applicable)
If your microwave is ducted externally, there may be a metal vent pipe connected at the top. Unscrew and disconnect it from the microwave’s damper.
If your microwave is ductless (recirculating), you can skip this step.
Step 3: Unplug the Microwave
Remove the microwave’s power plug from the upper cabinet outlet.
Step 4: Remove Mounting Bolts
Have your assistant hold the microwave while you unscrew the two bolts that secure the unit from the cabinet above.
Step 5: Tilt and Lift Out the Microwave
Carefully tilt the microwave downward and lift it off the rear mounting bracket. Set it down on a towel-covered counter or other protected surface.
Step 6: Remove the Rear Mounting Plate
Use a screwdriver to remove the rear mounting bracket from the wall. Save the screws or replace them if needed.
Part 2: How to Install a Range Hood？
Always check your hood’s installation manual before starting. If hardwiring is needed, consult a licensed electrician.
Step 1: Choose and Mark the Installation Location
Use the included paper installation template to mark where the vent hole and mounting screws should go. Measure and find the wall’s center point above your stove.
Step 2: Check Inside the Wall
Before cutting anything, cut a small section of drywall where the vent will go and inspect for pipes or wires. If you find obstructions, you may need professional help.
Step 3: Cut the Interior Vent Hole
Use an oscillating tool or reciprocating saw to cut the vent hole inside the wall (typically 6 inches wide). Drill four pilot holes around the edges to align with the exterior vent location.
Step 4: Cut and Seal the Exterior Vent Hole
Outside your home, use those four pilot holes to guide your cut. Cut a circular or square hole, apply sealant around the inside edge of the wall cap, and screw the vent cap into place. Apply exterior sealant for weatherproofing.
If your siding is uneven, add PVC trim around the vent hole and seal it.
Step 5: Install the Damper and Duct
If your range hood comes with a damper, install it at the interior side of the vent hole. Measure and cut the duct to connect the interior and exterior dampers, then secure with foil tape or metal clamps.
Step 6: Connect the Wiring
Many range hoods require hardwired electrical connections. If your kitchen isn’t wired for this, consult an electrician. Follow the instructions for connecting black (hot), white (neutral), and green (ground) wires.
Step 7: Mount the Range Hood
With help, hold the range hood in place and align it with the duct and wall anchors. Remove the filters temporarily and use the mounting slots to screw the hood into place. Use a level to ensure it’s straight before tightening.
Step 8: Finish the Wiring
Secure all wiring with connectors or wire nuts. Tuck wires inside the unit according to the manual. If unsure, get an electrician to double-check connections.

Does the Type of Vent Hood Matter for Height Above the Range?
Yes, different types of hoods have different airflow capacities, designs, and safety requirements — all of which affect how high they should be mounted.
Here are general guidelines based on hood type:
Wall-Mounted & Under-Cabinet Range Hoods:
Typically installed 24 to 30 inches above the cooktop. This allows effective smoke capture without being too low to interfere with cooking or too high to lose suction power.
Island Range Hoods:
Usually require a 30 to 36 inch clearance due to their open placement — and may need more powerful motors since they don’t have a wall to help contain airflow.
Downdraft Vents:
These are installed beside or behind the cooktop and pull air horizontally or downward, so vertical clearance isn't relevant — but proximity to the burners still matters for efficiency.
Microwave Vent Hoods (OTR):
Typically installed 13 to 18 inches above the range, but often don’t perform as well due to limited suction and positioning.

What if I Don’t Have Enough Range Hood Clearance Above the Stove?
If you don’t have enough vertical space between your stovetop and cabinets or ceiling for a traditional hood, don’t worry — you still have several options:
1. Install an Under-Cabinet Range Hood
These compact models fit under upper cabinets and are often shallower, allowing for a lower profile without sacrificing ventilation.
2. Go Portable
A portable range hood like the Ciarra Hood To Go offers flexibility and can be used without permanent installation — ideal for renters or compact kitchens.
