When considering a range hood for your kitchen, it’s important first to understand the primary categories of these appliances. Range hoods are typically divided into two main types: ducted and ductless systems.
What Is A Recirculating Range Hood?
A ductless range hood, commonly referred to as a recirculating range hood, works differently. Instead of venting air outside, it filters the air and circulates it back into the kitchen, removing smoke, fumes, and odors while introducing heat and moisture back into the room.
Convertible vs Recirculating Range Hood
When comparing convertible and recirculating range hoods, it’s important to understand the differences in how they function and the type of installation they require.
Convertible Range Hood
Convertible range hoods can be installed in two different ways: ducted or ductless. In ducted mode, they expel air outside through a vent, while in ductless mode, they recirculate air back into the kitchen after passing through a filter.
If you have the option to vent air outside, you can use it in ducted mode for better air quality. If you don’t have the space or ability to vent outside, you can switch it to ductless mode and rely on the filters to clean the air.
Recirculating Range Hood
A recirculating range hood only operates in a ductless mode. It pulls in air, filters out grease, smoke, and odors, and then returns the cleaned air back into the kitchen.
While this type of hood is convenient, it’s often less effective at clearing smoke and odors compared to a ducted range hood. The air recirculates back into the kitchen, so it may not remove pollutants as thoroughly as venting outside.
Keep your cooking habits in mind and consider investing in a higher-quality filter when purchasing.
Types of Recirculating Range Hood
1. Stainless Steel Recirculating Range Hood
A sleek, durable, and easy-to-clean option, this type of range hood adds a modern, stylish touch to any kitchen. Stainless steel construction ensures longevity and resistance to heat and moisture.
2. Under Cabinet Recirculating Range Hood
Installed beneath kitchen cabinets, this type is compact and discreet, perfect for kitchens with limited space. It effectively filters air before recirculating it back into the room, without taking up extra countertop space.
3. Wall-Mounted Recirculating Range Hood
Mounted on the wall above your cooktop, this option adds a striking focal point to your kitchen. It’s ideal for open-concept spaces, offering powerful filtration while enhancing your kitchen's design.
4. 24-Inch Recirculating Range Hood
A more compact model, this 24-inch range hood is suitable for smaller kitchens or cooktops. Despite its smaller size, it still provides effective filtration and odor removal in confined spaces.
5. 30-Inch Recirculating Range Hood
This mid-sized range hood is one of the most common options, providing ample coverage for standard cooktops. It balances performance and size, making it a versatile choice for many kitchen layouts.
6. 36-Inch Recirculating Range Hood
Ideal for larger cooking areas or professional-grade cooktops, this 36-inch range hood offers enhanced airflow and filtration. It’s perfect for those who need a more powerful unit for higher cooking demands.
Pros and Cons of Recirculating Range Hoods
Pros:
1. Initially Cheaper
Recirculating range hoods typically have a lower upfront cost compared to ducted models, making them more budget-friendly.
2. Environmentally Friendly
Since they don’t require external venting, recirculating hoods help reduce energy consumption and maintain the integrity of your home's structure.
4. Aesthetic Design
These range hoods often come in sleek, modern designs that can complement any kitchen decor. Their stylish appearance can serve as a focal point.
Mobility: Unlike ducted hoods, recirculating range hoods can be installed anywhere in the kitchen. Their portability makes them an ideal choice for renters or spaces where ducting isn’t feasible. Some models even turn off automatically after use, saving both time and energy.
Cons:
1. Recirculation Design
The air is filtered and recirculated back into the room, meaning some odors and smoke may linger longer compared to ducted systems, which vent air outside.
2. Noise
Depending on the model, recirculating range hoods can be noisier than ducted options due to the nature of the filtration and air circulation process.
3. Can Be More Expensive
While the initial cost is lower, high-quality recirculating range hoods with advanced filters can sometimes be more expensive in the long run.
How Do Recirculating Range Hoods Work?
Recirculating range hoods work by drawing in air from the kitchen, filtering out grease, smoke, and odors, and then recirculating the cleaned air back into the room. Here's how the process typically works:
Air Intake
The range hood pulls in the air from the cooking area, usually through a vent located near the top of the unit.
Filtration
The air passes through filters inside the range hood. These filters are usually made of:
-
Grease filters: To capture grease and oil particles.
-
Carbon filters: To remove odors and some pollutants from the air.
- Cleaning: As the air passes through these filters, grease, smoke, and unpleasant odors are trapped, while the cleaned air continues its flow.
Recirculation
The cleaned air is then pushed back into the kitchen, usually through a vent or slats at the front of the hood.
Unlike ducted range hoods, which vent the air outside, recirculating hoods do not require external venting and are more flexible in terms of installation. However, since the air is not expelled outdoors, the system relies heavily on the filters to ensure the air quality remains acceptable.
The effectiveness of a recirculating range hood largely depends on the quality of its filters, and regular maintenance (like replacing or cleaning the filters) is essential to ensure optimal performance.
Are Recirculating Range Hoods Effective?
When it comes to maintaining a healthy and comfortable kitchen environment, understanding the science behind air filtration and circulation is essential. Proper ventilation, specifically through the use of range hoods, plays a critical role in improving indoor air quality.
Cooking, while a delightful experience, generates various byproducts, including visible elements such as grease and smoke, as well as less obvious but equally significant pollutants.
Several studies and expert opinions highlight the importance of efficient kitchen ventilation. For instance, the Environmental Protection Agency (EPA) notes that cooking activities can release not only visible particulate matter like smoke and grease but also ultrafine particles that linger in the air. These ultrafine particles, which are often invisible, can contribute to indoor air pollution and may lead to respiratory issues or other health problems.
Recirculating range hoods address these concerns by capturing both large particles (like grease) and smaller particles (like smoke and odors). However, their effectiveness largely depends on the quality of their filters and how regularly they are maintained. That's where Ciarra's range hoods with plasma filtration come in, offering a superior solution for your kitchen air quality.

Are Recirculating Range Hoods Any Good?
Recirculating range hoods are a solid choice if you're looking for a budget-friendly, easy-to-install option and can’t vent air outside. They can effectively handle grease and odors with regular filter maintenance. However, if air quality is your top priority or you cook with heavy smoke or strong odors frequently, a ducted range hood might be more effective in the long term.
Ciarra’s recirculating range hoods with plasma filtration offer an even better solution, enhancing air quality by not only filtering grease and smoke but also eliminating harmful bacteria, allergens, and viruses. This makes them an excellent choice for those who want better air quality in their kitchen while minimizing the need for frequent filter replacements and maintenance.
How to Install a Recirculating Range Hood?
For a ductless range hood, there's no need for external venting, as the air is filtered using charcoal filters and recirculated back into the kitchen. Here’s a step-by-step guide to installing a ductless range hood:
Tools and Materials Needed
Recirculating range hood unit
Mounting brackets (usually included)
Screws and anchors (usually included)
Drill and drill bits
Screwdriver
Measuring tape
Level
Pencil
Charcoal filters (if not pre-installed)
Installation Steps:
1. Choose the Installation Location:
Select a location above your cooktop or range. Ideally, the range hood should be mounted 24-30 inches above the cooking surface for optimal performance.
Ensure there’s enough space around the hood for proper air circulation and consider any overhead cabinets or shelves.
2. Prepare the Wall or Cabinet:
Measure and mark the position for the mounting brackets. Use a pencil to mark the spots on the wall or under the cabinet where the hood will be installed.
Make sure the area is level by using a measuring tape and a level.
3. Install the Mounting Brackets:
Attach the mounting brackets to the wall or under the cabinet where you marked the spots. For drywall installation, use anchors for a secure fit. For concrete or brick walls, use masonry anchors.
Use a level to ensure the brackets are straight before securing them.
4. Install the Charcoal Filters:
Ductless range hoods require charcoal filters to clean the air. Follow the manufacturer's instructions to install the charcoal filter inside the range hood. Make sure it's properly placed to ensure maximum filtration.
5. Electrical Connections:
Like ducted models, you'll need to connect the electrical wiring to the range hood. Ensure the power is off, then run the wiring and connect the wires using wire connectors.
If you’re not comfortable working with electricity, it’s a good idea to call a licensed electrician for this step.
6. Mount the Range Hood:
Mount the hood in the same manner as ducted models, but there is no need to install a vent cap or connect a duct. Simply secure the range hood to the wall or under the cabinet as per your model’s instructions.
Make sure the unit is securely mounted and level.
7. Test the Range Hood:
After installing, turn the power back on and test the range hood. Make sure the fan works and that the air filtration system is effectively recirculating the air. Check that the charcoal filter is functioning properly to trap smoke, grease, and odors.

Key Differences Between Ducted and Ductless Installation:
Vent Hole: Ducted range hoods require cutting both an interior and exterior vent hole, while ductless models do not need any vent holes.
Venting Pipe: Ducted range hoods need a vent pipe to expel air outside, whereas ductless models use filters to recirculate air back into the room.
Charcoal Filters: Only ductless models require the installation of charcoal filters inside the range hood to filter out odors and grease.
Exterior Vent Cap: A vent cap and damper are necessary only for ducted models to expel the air outside.

Conclusion
Recirculating range hoods do work, but their effectiveness depends on your specific needs. They are a great option for light to moderate cooking and kitchens where venting outside isn't possible. However, if you do a lot of heavy cooking or want the most powerful air filtration, you may want to consider a ducted range hood instead.
With the right maintenance and filter replacement, a recirculating range hood can still provide good air quality and keep your kitchen fresh. Just be mindful that while they can neutralize odors and reduce grease, they won’t be as powerful as their ducted counterparts at removing all cooking pollutants from the air.
