What is a recirculation range hood?

Most cooker hoods use an air outlet to the outside. But what if you do not have air exhaust? Without a hood you are nowhere; after all, you just want to cook without the kitchen turning blue and the whole house smelling like frying. A recirculation hood is the solution, but works less well than an air exhaust extraction hood. In this article I explain what a recirculating extraction hood is, how it works and what the disadvantages are.

How does a recirculation extractor work?

recirculating extraction hood

A recirculation hood extracts the air, filters it, and blows it back into the kitchen. The air is circulating. Hence the name 'recirculation extractor'. There are carbon filters in the extractor hood. Carbon has the property by nature to absorb dirt. When the extractor hood sucks the cooking air, the carbon filter absorbs dirt and odors from the air. The air is clean and the hood blows it back into the room.

What are the advantages and disadvantages of a recirculation extraction hood?

  • Is suitable for kitchens without discharge to the outside The extractor hood filters the air clean, making it suitable for use in kitchens without an air outlet to the outside.
  • You have to change the carbon filters regularly

In a recirculation hood, the carbon filters absorb the dirt from the sucked-up air. At a certain moment they are satisfied and you have to replace them. How long you use a filter depends on the type of filter, how often you use the cooker hood, and what you cook. A normal filter lasts an average of 6 to 8 months.

  • He takes away less odor

A recirculation hood extracts about 85 to 90 percent of the odors from the cooking air. As you use the filter for a longer time, the effect will deteriorate and odors will hang faster.

  • He makes more sound

Because of the 'extra' part, the filter, the extraction hood makes more noise. How much exactly is described in the product specifications on the product page on our website.

  • He has less suction

The suction is less good if you use the extractor hood as a recirculating cooker hood. The suction reduces by 20 to 30 percent when you do not use the hood with air exhaust.

Which recirculation hoods are there?

You buy a recirculation hood usually as an exhaust air exhaust hood. You must then make it suitable for recirculation by placing a filter. In some cases you have to convert it with a recirculation set. The product page shows which of the two ways you can make the product suitable for recirculation.

How do I build an air exhaust extraction hood?

recirculation kit

The conversion of your extractor hood is done once with a recirculation set. These are different per brand and they are product specific. Buy a set that is suitable for your product. The recirculation set is almost never included with the hood, so you order it separately. After you have installed the set, you only have to replace the filters regularly.
