A recirculating range hood (sometimes referred to as a ductless range hood) is a type of ventilation system commonly found above stovetops in kitchens. Unlike ducted range hoods that vent air outside, recirculating range hoods filter the air and then release it back into the kitchen.

Recirculating range hoods use a combination of filters to remove grease, smoke, and odors from the air. The first filter, typically made of aluminum or stainless steel, captures grease particles. The second filter, often made of activated charcoal, helps to eliminate odors. Once the air passes through these filters, it is recirculated back into the kitchen, creating a cleaner and more pleasant cooking environment. While recirculating range hoods may not be as efficient as ducted models, they are a practical option for kitchens without access to external ventilation.

We always recommend ducting your range hood to the outside as it will be more efficient than a ductless one, but there are some cases when ducting to the outside is not possible. Only in this situation do we recommend using a recirculated range hood. With time the performance of the recirculated hood decreases, as the filter becomes dirtier, clogged, absorbs the oil and restricts the air even more. All charcoal filters need to be replaced every 3-6 months, depending on your cooking needs. If you're not sure if a ductless range hood is the right choice for you, remember to ask a professional. Our team of range hood experts are also able to help you decide between a ducted range hood, and a ductless one.
