An under cabinet range hood mounts directly to the underside of your upper cabinets, sitting above the cooking surface without requiring wall space or ceiling clearance. It does one job well: pull cooking air upward through filters before grease, steam, and odors spread through your kitchen.
It is one of the most common range hood types in residential kitchens because it fits the standard layout most homes already have, keeps a low profile, and handles everyday cooking without major installation complexity.
Here is what you need to know everything about an under cabinet kitchen hood before you buy one.

What an Under-Cabinet Range Hood Does and How It Works
Understanding the basic mechanics helps you set realistic expectations from day one. When you cook, your range releases grease, steam, smoke, and odors. Without ventilation, those byproducts settle on your cabinets, walls, and surfaces over time and gradually affect your indoor air quality.
An under cabinet range hood captures those byproducts at the source. A motorized blower draws air upward through grease filters at the base of the unit. The filters trap grease particles before they reach the duct or the blower motor. From there, the air either travels outside through ductwork or passes through charcoal filters and returns to the kitchen, depending on the configuration.
The hood sits at a fixed height set by your upper cabinet installation, typically 24 to 30 inches above the cooktop. That clearance distance is one of the key factors in how well the unit captures what your range produces.
Ducted or Ductless: Know Which One Your Kitchen Needs
This is the first decision to make, and it matters more than most buyers realize. A ducted range hood runs a duct from the hood to an exterior exit point, sending grease, moisture, cooking odors, and airborne byproducts completely out of the building. This is the higher-performing option. If your kitchen has an accessible duct route, ducted is the configuration to pursue.
A ductless range hood, also called a recirculating range hood, uses charcoal filters to absorb odors before returning the air to your kitchen. It does not remove heat or moisture. It works adequately for light everyday cooking, but performance drops when you let the charcoal filters go too long between replacements, typically every three to six months.
To figure out which setup your kitchen supports, check for duct access above your upper cabinets or through the wall behind the range. If duct access is there, use it.

CFM: How to Know If the Hood Is Powerful Enough
CFM stands for cubic feet per minute. It tells you how much air the hood can move each minute, and it is the most important specification to get right. Under cabinet range hoods typically fall between 200 and 600 CFM, which covers most residential cooking situations when matched correctly to the range.
Gas range sizing follows a practical calculation: divide your cooktop’s total BTU output by 10,000 and multiply by 100 to get your minimum CFM rating. For electric ranges, use 100 CFM per 10 inches of range width. A 30-inch electric range needs at least 300 CFM. A 40,000 BTU gas range needs at least 400 CFM.
A variable speed hood gives you more control. You can run it quietly during light cooking and dial it up when things get serious. Fixed-speed hoods offer no middle ground and are harder to adapt to different cooking situations.

What to Realistically Expect From This Type
Under cabinet range hoods perform well within specific limits, and knowing those limits upfront is useful. The main one is front-burner capture. Because the hood draws air straight up, rear burners directly below it are served well. Front burners sit at the outer edge of the capture zone, and steam or grease from those burners can drift forward before the airflow catches them, particularly during high-heat cooking.
Higher CFM ratings and a deeper canopy reduce this gap but do not eliminate it. For moderate everyday cooking on a standard residential range, you will not notice the limitation much. For frequent high-heat cooking or high-BTU gas ranges, a wall mount hood with a wider canopy is a better fit.
Which Kitchens Actually Suit an Under-Cabinet Hood?
Before you shop for a specific model, confirm that this type actually fits your kitchen. An under cabinet range hood works when your range sits against a wall with upper cabinets mounted directly above it. The hood mounts to the underside of those cabinets, so the cabinet structure carries its weight. Check that the cabinets are in solid condition before installation.
It does not work if your range is on a kitchen island, if there are no upper cabinets above the range, or if your layout is open-plan with no wall behind the cooking surface. In those cases, a wall mount range hood or an island range hood is the correct type.
What to Check Before You Buy an Under Cabinet Hood
A few category-level decisions narrow your choices significantly before you look at specific models. Width should match your range at minimum. Standard sizes are 30 and 36 inches. Going narrower than your range leaves edge burners outside the full capture zone.
CFM should meet your range’s sizing calculation with a reasonable buffer built in. Variable speed models are more practical than fixed-speed across different cooking situations.
Filter type matters if you cook regularly. Baffle filters require less maintenance than mesh under equivalent cooking loads.
Noise is measured in sones. Below 4 sones is comfortable for most households. Above 6 sones becomes noticeable in a quiet kitchen. If your kitchen opens to a living area, prioritize models that publish their sone rating at medium speed, not just at maximum.

How Difficult Is an Under-Cabinet Hood Installation?
For most capable DIYers, under cabinet range hood installation is manageable in a standard kitchen. Three variables determine how involved it gets: cabinet condition, duct access, and electrical access.
Your upper cabinets need to be structurally sound enough to support the hood’s weight. Running new ductwork through finished walls or ceilings adds complexity and often warrants professional help for that portion of the job. Most hoods connect to a 120-volt household circuit. If no circuit is available near the installation point, an electrician needs to run one before the hood goes in.
Ductless models skip the exterior duct run but carry the same electrical requirements.

Frequently Asked Questions
Can an under cabinet range hood be installed without exterior ductwork?
Not necessarily. Ducted models exhaust cooking air to the exterior through a duct run and deliver better overall performance. Ductless models filter and return air to the kitchen through charcoal filters, making them a practical option when exterior duct access is not available in your kitchen.
How wide an Under-Cabinet Hood should it be?
Width should equal your range at minimum. A 30-inch hood for a 30-inch range, a 36-inch hood for a 36-inch range. Going narrower leaves the edge burners outside the capture zone.
How does it differ from an over-the-range microwave?
An OTR microwave bundles basic ventilation into the microwave unit. A dedicated under cabinet range hood focuses entirely on ventilation and delivers meaningfully higher CFM and better capture performance. The OTR microwave trades that ventilation performance for counter space savings. See exactly how the two compare in our OTR microwave vs range hood guide.
What is the difference between mesh and baffle filters?
Mesh filters trap grease through layered aluminum and need frequent cleaning. Baffle filters separate grease through directional airflow changes and require less maintenance under the same cooking load. Baffle is the better-performing option for regular cooking use.
