How Do Under-Cabinet Range Hoods Work?

March 20, 2023 5 min read

A range hood is a must-have in many modern kitchens because it swiftly clears the air of smoke, grease, and other pollutants. They come in different shapes, sizes, and forms, each with benefits and drawbacks.

Under-cabinet range hoods are one of the most popular kitchen range hoods because of their flexibility. Unlike other range hoods that stand out or require extensive space, these are stealth vent hoods, which are an excellent option for smaller kitchens.

Even though they are popular kitchen hoods, relatively few internet articles adequately explain what an under-cabinet range hood is. This article will correct that oversight and give you an in-depth overview of under-cabinet range hoods. So read on.

Under-Cabinet Range Hoods Work?

What is an Under-Cabinet Range Hood?

An under-cabinet range hood is a type of ventilation system often installed below the kitchen cabinet, right above the cooking area. They are excellent kitchen air purifiers that use suction fans and filters to remove steam, vent smoke, trap grease, and absorb strong odors.

Under-cabinet range hoods are one of the best options for kitchens where you don’t cook large meals or often, have little space, or have no extensive duct system. They are primarily installed unobtrusively, with their ductwork hidden from view, and they blend seamlessly with your kitchen decor.

The ducting and wiring in an under-cabinet range hood are concealed and blend in with the rest of the kitchen. Everything about an under-cabinet range hood screams a conservative approach to maximizing kitchen space without giving up much in terms of venting power.

How Does an Under Cabinet Range Hood Work?

Under-cabinet range hoods are typically placed beneath kitchen cabinets directly above the cooking area. They take up space reserved for low-sitting cabinets and are optimally located to provide enough coverage over the cooking area.

An under-cabinet range hood uses a suction fan (blower) to draw in polluted air that contains smoke, heat, and cooking odors from your kitchen. The fan pulls the contaminated air through its vent hood, which houses dual stainless steel baffle filters that trap grease and oils, preventing them from recirculating back into the air. Once the stainless steel filter has separated the grease and oily particulates, the air is drawn through a charcoal filter. This filter removes any remaining cooking odors, ensuring that the air released back into your home is clean and fresh.

Different Types of Under Cabinet Range Hoods

Under-cabinet range hoods come in various types and styles, each with unique features and benefits. We will discuss the different kinds of under-cabinet range hoods, their features, and the factors to consider when choosing the right one for your kitchen.

When choosing an under-cabinet range hood for your kitchen, your options are ducted under-cabinet range hoods, ductless under-cabinet range hoods, and convertible under-cabinet range hoods.

1.     Ducted Under-Cabinet Range Hoods

Ducted under-cabinet hoods are the most common type of range hood and are connected to the ductwork in your home. They work by drawing air from the kitchen, filtering it, and expelling it outside.

An under-cabinet ducted hood is ideal for kitchens with a good ventilation system and perfect for homes with a centralized HVAC system that replenishes the kitchen constantly with fresh air.

The primary advantage of having a ducted range hood is that all contaminants get released outdoors, ensuring that the kitchen remains free of smoke, heat, and cooking odors. This type of range hood is also easy to clean and maintain, making it a practical and convenient option for many homeowners.

2.     Ductless Under Cabinet Range Hoods

Ductless under-cabinet hoods are an excellent option for those who do not have access to ductwork in their homes. They are recirculating hoods that clean the kitchen air and recycle it back into the kitchen.

They function by filtering the kitchen air as it passes through a series of filter units. Like any ductless range hood, they are often not as powerful as their ducted range hoods counterparts, but they offer adequate ventilation in most kitchens.

3.     Convertible Under Cabinet Range Hoods

Convertible under-cabinet hoods can be used as either ducted or ductless range hoods. They have duct outlets that connect to external pipes or ductwork and contain recirculating kits with filter units when operating as ductless hoods. This type of range hood is the ideal ventilation unit for those who want the flexibility to switch between ducted and ductless operation.

Benefits of an Under-Cabinet Range Hood

Certain benefits make installing an under-cabinet range hood a quality decision. Some of the best ones include:

1.     Very simple installation

Under-cabinet range hoods are designed to be very nimble and easy-to-install kitchen appliances. They don’t have too many complex parts and come with detailed installation guides, which means they can be self-installed if the proper tools are available. The substantial savings from not having to hire an installer and make significant modifications to the kitchen make them a cost-effective option for most kitchen owners.

2.     Space saving

An under-cabinet range hood is the perfect range hood for any kitchen where space is a significant problem. They integrate and function well in confined spaces, with all ducting concealed in the walls or above the cabinet. External parts like the under-cabinet hoods have a compact design that takes up little cabinet space. This is quite different from other range hoods, like an island range hood with big vent hoods that take up much space. You can effectively clean your kitchen air with a range hood that doesn’t cover much space, leaving room for adding other kitchen appliances.

3.     Energy efficient

These are ultra-modern devices made with the latest innovative technologies that offer premium energy savings when used correctly. Their power consumption is significantly reduced by adding efficient features like regulated starts and stops, customizable fan speeds, and brushless DC motors. This reduction in power usage doesn't come with any compromise in performance, which is downright impressive. They are perfect for homeowners who are very conservative about the energy use of their appliances.

4.     Easy maintenance

Most under-cabinet range hoods are made of stainless steel and have parts made of cleaning agent-friendly materials. This makes them considerably easy to clean and maintain, which is another cost-saving feature. They are made with readily replaceable parts, are positioned in an accessible location, and are simple to clean using standard cleaning products. In addition, they are equipped with dishwasher-safe filters that allow the owners to reuse a single filter rather than replace it entirely.

5.     Lots of modern features

Being a modern range hood, they offer convenient features like built-in lights, push-button controls, exhaust timer control, multi-fan speed settings, etc. This means they can be easily operated, and the lighting system provides additional illumination for the cooking area. The multi-fan speed settings allow for adjustable fan speeds that vent air at a slower pace to reduce the noise level of the blowers.

It also helps keep your kitchen free of grease and other spills, making it easier to clean and maintain.
