In many UK homes — especially in flats, terraced houses, or listed buildings — installing a traditional ducted cooker hood can be a challenge. External wall access is often limited, and building regulations may restrict structural changes. That’s where recirculating cooker hoods with carbon filters come in as a practical, efficient, and stylish solution.
What is a Recirculating Cooker Hood?
A recirculating cooker hood, also known as a ductless hood, doesn't require an external vent. Instead, it draws in cooking fumes, passes them through a set of filters — including a grease filter and an activated carbon filter — and then recirculates the cleaned air back into the kitchen. Many integrated cooker hood models are designed with this recirculating system in mind, making them a popular choice for UK homes where external ducting isn't possible.
Why Carbon Filters Matter
The carbon filter plays a vital role by absorbing odours, smoke, and airborne grease particles. These filters contain activated carbon granules with a porous structure that traps pollutants, significantly improving indoor air quality.
Carbon filters are used across various styles of recirculating cooker hoods, giving homeowners plenty of flexible installation options to suit different kitchen layouts. Here are some common types:
Recirculating Cooker Hood without Chimney
A sleek and modern choice, ideal for minimalist kitchens or where space is limited. Without a bulky chimney, it integrates seamlessly into compact settings.
Angled Recirculating Cooker Hood
Stylish and ergonomic, angled hoods provide better headroom while efficiently drawing up cooking fumes through internal filtration systems.
Wall-mounted Recirculating Cooker Hood
A classic option that offers powerful air recirculation, perfect for homes where ducting outside isn't possible.
Island Recirculating Cooker Hood
Designed for kitchen islands, these hoods offer 360-degree air capture and circulation. With integrated carbon filters, they’re ideal for open-plan spaces where external venting isn’t feasible, combining statement design with efficient air purification.
How Do Recirculating Cooker Hoods Work?
Unlike traditional ducted hoods that expel air outside through a vent, recirculating cooker hoods operate on a closed-loop system.
Here’s how they work:
Extraction
The hood draws in air containing cooking fumes, smoke, and grease.
Filtration
The air first passes through a grease filter (usually made of aluminium or stainless steel) which captures oil and grease particles. It then moves through an activated carbon filter that neutralises odours, smoke, and other airborne pollutants.
Recirculation
Once filtered, the clean air is released back into the kitchen, improving air quality without the need for external ducting.
Do Recirculating Cooker Hoods Remove Moisture?
Yes, recirculating cooker hoods can help reduce moisture in the kitchen. While their primary function is to remove grease, smoke, and odours through carbon and grease filters, they also contribute to maintaining a drier, fresher cooking environment.
By filtering out steam and airborne particles, these hoods can help prevent excess humidity, which in turn reduces the risk of mould, mildew, and bacterial growth — common problems in poorly ventilated UK kitchens.
This makes recirculating hoods not only a practical choice for homes without external venting but also a valuable addition for keeping your kitchen cleaner, healthier, and more comfortable.

Is It Right for Your Kitchen?
If you're renovating a kitchen in a Victorian terrace, a flat in London, or even a new-build without external venting, a recirculating cooker hood is an excellent option. It's also a smart choice if you want to avoid the disruption of installing ducting through walls or ceilings.
However, for heavy-duty cooking (e.g. deep frying or spicy meals), a ducted hood may offer slightly better long-term air removal. But for the majority of UK households, especially those with open-plan layouts or light-to-moderate cooking habits, a recirculating hood is more than sufficient.
How to Install a Recirculating Cooker Hood?
If you've purchased a Ciarra cooker hood, installing it yourself is completely doable. Ciarra designs its recirculating hoods for easy, hassle-free installation — many customers manage it alone without professional help.
To get started, simply refer to the user manual included with your model. You can also visit the official Ciarra website to search for your model number and find step-by-step installation videos for extra guidance.
Here’s a quick overview of the main installation types:
Integrated (Built-in) Recirculating Cooker Hood
Installed inside a kitchen cabinet, this type is ideal for a streamlined look. Slide the hood into place, connect the wiring, and ensure the filters are correctly fitted.
Island Recirculating Cooker Hood
Mounted from the ceiling above a kitchen island, this type often comes with adjustable hanging brackets. It's designed for open-plan kitchens and connects directly to power with no need for external venting.
Wall-Mounted Recirculating Cooker Hood
Mounted directly to the wall above your hob, this type typically requires fixing the hood bracket, securing the hood, and connecting the power. With no ducting needed, it’s fast and simple.
How Often Should Recirculating Cooker Hood Filters Need Replacing?
Recirculating cooker hood filters—especially carbon filters—should be replaced every 3 to 6 months, depending on how often you cook. Grease filters may need cleaning or replacing more frequently. Always check your hood's user manual for model-specific guidance.
