When it comes to kitchen ventilation, one of the most important decisions is choosing between a ducted and a ductless range hood. Both types of range hoods serve the same basic function—removing smoke, odors, grease, and heat from your kitchen—but they work in different ways. Understanding the pros and cons of each will help you decide which option is best suited for your cooking space.
What is a Ductless Range Hood?
A ductless range hood is a kitchen ventilation system that does not require external venting. Instead of expelling air through a duct to the outside, ductless range hoods use filters, typically charcoal filters, to purify and recirculate the air back into the kitchen. This makes them ideal for kitchens where venting through an exterior wall or roof isn't feasible.
Type of the Ductless Range Hood
1. Ductless range hood insert
A ductless range hood insert is a built-in version of a range hood that fits into a custom cabinetry design, typically installed in a wall or under a cabinet. This type of hood has filters that trap grease, smoke, and odors, and the clean air is recirculated into the kitchen. These inserts are designed for kitchens without external venting options.
2. Ductless island range hood
A ductless island range hood is similar to a traditional range hood, but it is specifically designed to be installed above a kitchen island cooktop. Like other ductless models, it filters the air and recirculates it back into the room. These hoods are typically installed with a more visually striking design to suit the open space above an island.
3. Under cabinet range hood ventless 30 inch
An under-cabinet ventless range hood (30-inch refers to the width of the unit) is designed to be installed underneath a kitchen cabinet. This type of range hood doesn't vent air outside but instead uses filters (often charcoal) to clean the air before recirculating it back into the kitchen. The "ventless" aspect means no external venting system is needed.
Do Ductless Range Hood Need to Be Vented?
Ductless range hoods do not need to be vented to the outside. Instead of expelling air outside, they use filters (usually carbon or charcoal filters) to trap grease, smoke, odors, and airborne particles. The cleaned air is then recirculated back into the kitchen.
How Does a Ductless Range Hood Work?
A ductless range hood, also known as a recirculating range hood, works by filtering the air in your kitchen and then returning the clean air back into the room, rather than venting it outside through ducts. Here's a breakdown of how it works:
1. Air Intake
The range hood has an intake fan or blower that pulls the air, including smoke, grease, odors, and heat, from the cooking area. This is typically located directly above or around the cooktop.
2. Filtration
Once the air is drawn in, it passes through a series of filters designed to trap contaminants:
Carbon Filter (Charcoal Filter): After passing through the grease filter, the air passes through a carbon or charcoal filter. These filters are designed to absorb odors and smoke, neutralizing them before the air is recirculated back into the kitchen.
3. Air Recirculation
After the air is filtered, it is sent back into the kitchen. This process doesn't require any ducts to vent the air outside, which is why it's called ductless. The filtered air is typically returned through a vent located at the top or side of the hood.
Are Ducted or Ductless Range Hoods Better? Pros and Cros
When choosing between ducted and ductless range hoods, it ultimately depends on your kitchen setup and preferences. Both have distinct pros and cons, so let’s break it down:
WHAT IS A DUCTED RANGE HOOD:
- External ventilation
- Must be connected to a duct in your wall, ceiling or floor
- Limited in where it can be placed
- Helps reduce smokes, odors and grease from home
Pros:
- Effective Ventilation: Ducted hoods are more efficient at removing smoke, steam, odors, and grease from the kitchen. The air is exhausted outside, which means it won’t recirculate.
- No Filters to Replace Frequently: While you may need to clean the filters, there are no carbon filters that need constant replacing.
- Improved Air Quality: Since the air is vented outside, ducted systems improve indoor air quality by removing pollutants.
- Better for Larger Kitchens: If you have a larger kitchen or heavy cooking needs, ducted hoods are usually more effective due to the direct airflow to the outside.
Cons:
- Installation Complexity: Ducting the air outside requires significant installation work, which can be expensive and complicated, especially in apartments or kitchens without an external wall.
- Space Requirements: The ductwork takes up space, which can be restrictive, especially in small kitchens or if you're trying to maintain a clean aesthetic.
- Cost: The upfront installation cost is higher due to the need for ductwork, and maintaining ducts over time can add additional costs.
WHAT IS A DUCTLESS RANGE HOOD:
- Recirculating ventilation
- Can be placed nearly anywhere
- Filters air instead of completely removing it
- Recirculates the air in the kitchen instead of venting out stale air
- Requires cleaning of filter
Pros:
- Easier Installation: No need for ductwork, making installation quicker and cheaper. This is ideal for renters or people living in apartments where venting outside isn’t possible.
- Flexible Location: Can be installed anywhere, even in kitchens without an external wall.
- Lower Initial Cost: Ductless systems are typically more affordable upfront than ducted ones.
- Simple Maintenance: Filters need to be replaced or cleaned periodically, but it’s generally easier than dealing with ductwork.
Cons:
- Less Effective Ventilation: Ductless hoods don't expel air outside, so the air stays within the kitchen and recirculates. This can result in lingering odors and less efficient grease removal.
- Filter Maintenance: The filters (especially charcoal filters) need to be replaced regularly. If you don't replace them often enough, the air circulation can worsen.
- Air Quality: While they reduce odors and smoke, they don’t do as much for humidity or other pollutants in the air compared to ducted systems.
What to Consider When Choosing Between Ducted and Ductless Range Hoods?
To choose which of these two types of hoods is right for your kitchen, you really need to examine your work space, your cooking style, and your personal preferences. You might have to mull over a few important questions regarding your kitchen situation before you pick the right range hood.
1. Size and fit: Ducted systems typically require more space for installation, as they need a duct to vent air outside. If you have a larger kitchen, a ducted range hood might be easier to install and more effective at removing heat, smoke, and odors. And these are more flexible in smaller kitchens or where it's difficult to install ducts. They filter air and recirculate it back into the kitchen, making them ideal for spaces without easy access to an exterior wall.
2. How Big is Your Cooktop?
The size of your cooktop will determine the size of the range hood you need. A larger cooktop (such as a 36-inch model) requires a larger, more powerful range hood. Both ducted and ductless options come in various sizes, but ducted systems generally have more powerful airflow and can cover larger cooking areas more effectively.
3. Quietness: Decibels (dBAs) measure the noise level of a range hood. The lower the number, the quieter it is. When looking at product specs, pay attention to the different dBAs listed, as these represent the level of sound created at the different vent speed settings.
Ductless hoods are quiet than duct hoods, but since they don’t require the air to travel through long ducts, they are often quieter than ducted models in certain situations. However, some may produce noise due to the fans or the charcoal filter.
4. What Amount of Ventilation Do You Need?
Venting power is measured in terms of cubic feet per minute (CFM). This number tells you how much air a vent can move in one minute. Generally, the higher the CFM rating, the stronger the venting power. When looking at product specs, remember that CFMs relate to the highest speed setting on a range hood, and canopy and downdraft hoods tend to have higher CFM ratings. However, how much CFM you need depends on a number of factors including the size of your kitchen and the type of cooking you do. Ducted hoods are more effective at keeping your kitchen air clean, removing other airborne particles, dissipating heat, and reducing kitchen humidity than ductless range hoods. If clean air is a must for medical reasons or personal preferences, then ducted range hoods are the safer option.
5. How Often Will You Cook with Your Stovetop?
If you cook frequently, a ducted range hood is typically the better choice because it offers stronger, continuous airflow, which will help with ventilation over long periods.
If you only cook occasionally or at lower heat settings, a ductless range hood might be sufficient, as it will handle light to moderate cooking needs adequately.
6. What Are Your Budget Constraints?
Ducted Range Hood: Generally more expensive upfront due to installation costs (if ducts aren’t already in place), but they tend to last longer and are more effective at ventilation.
Ductless Range Hood: Less expensive in terms of installation, as there are no ducting costs involved. However, you may need to replace filters more often, which can add to long-term costs.
By weighing these factors, you can choose the range hood that best fits your kitchen setup, cooking habits, and ventilation needs.
Ductless range hoods offer greater flexibility when it comes to installation
Unlike ducted models, they don't require external ductwork, allowing them to be placed in more locations within the kitchen. This makes them ideal for spaces where installing a vent to the outside would be difficult or impractical.
Additionally, ductless range hoods are simple to install as a DIY project. With basic tools like a level, drill, and hammer, you can typically have one mounted in about an hour. In contrast, installing a ducted range hood in a kitchen without existing ductwork is more complex, as it involves cutting holes, running ducting, and installing a blower system.
How to Install Ductless Range Hood?
Installing a ductless range hood is a relatively straightforward process, making it a good DIY project for those comfortable with basic tools. Here’s a step-by-step guide to help you install your ductless range hood:
Installation Steps:
1. Choose the Installation Location
Placement: Position the range hood directly above your cooktop or stove, ideally between 24 to 30 inches above the surface for optimal air intake and performance.
Clearance: Ensure the location allows for the proper airflow and that it’s easily accessible for maintenance.
2. Measure and Mark the Mounting Points
Height: Use a tape measure to mark the proper height above the cooktop (usually between 24 and 30 inches for optimal performance).
Width and Centering: Ensure the range hood is centered over the stove for even coverage. Mark the positions for the mounting holes on the wall and ceiling (or cabinet, depending on the installation style).
3. Drill Holes for Mounting
Using the marks you made, drill holes for the mounting brackets. If you’re installing the range hood under a cabinet, make sure to drill into the wood or metal of the cabinet for a secure fit.
If the installation requires anchoring to the wall, use the appropriate anchors or screws depending on the wall type (drywall, plaster, etc.).
4. Install the Mounting Brackets
Attach the mounting brackets to the wall or under the cabinet using screws and a screwdriver. Make sure they are level and secure.
5. Attach the Range Hood
With assistance (if needed), carefully lift the range hood and hang it onto the mounted brackets. Check that it’s level before securing it into place.
Use screws to secure the range hood to the brackets or mounting plate.
6. Install the Carbon/Charcoal Filter
Most ductless range hoods come with a carbon/charcoal filter designed to trap odors and smoke. Install the filter by following the manufacturer's instructions—usually, it slides or snaps into place inside the hood.
7. Connect the Power
Plug the range hood into the electrical outlet or connect it to the hardwiring, depending on the model. If the hood is hardwired, it’s recommended to hire an electrician to safely make the electrical connections.
Make sure the fan is functioning and the light works (if applicable).
Maintenance Tip:
Remember to regularly clean and replace the carbon/charcoal filter (every 3–6 months, depending on usage) to keep the range hood functioning optimally.
With these steps, your ductless range hood should be installed and ready to improve your kitchen’s air quality.
How Do You Clean a Ductless Range Hood?
Here’s a refined version of your instructions on cleaning a ductless range hood:
Remove the Grease Filter:
Begin by removing the screw that holds the grease filter retainer in place.
Turn the retainer, pull it towards you, and away from the fan to detach it.
Clean the Filter:
Wash the grease filter in the dishwasher (if it’s dishwasher-safe) or soak it in a hot detergent solution.
Let the filter dry completely before reinserting it.
Reassemble the Hood:
Once the filter is dry, carefully screw the retainer back in place and secure the filter.
Cleaning Tips:
Always refer to the manufacturer's instructions in the owner’s manual for specific disassembly and cleaning instructions, as these may vary by model.
Things to Avoid:
- Harsh cleaning tools: Avoid soap-filled scouring pads, abrasive cleaners, cooktop polishing creams, steel wool, gritty washcloths, or paper towels.
- Chlorine-based cleaners: Never use cleaners containing chlorine on stainless steel parts to avoid damage.
