how do recirculating cooker hoods work

Cooking can be an exciting experience, but it always comes with its own set of challenges. One of the biggest issues that many home cooks face is dealing with smoke and odours from cooking. Fortunately, recirculating cooker hoods offer a great solution for this issue. These devices work by extracting air and filtering out any smoke or odours before returning the air back into your kitchen. In this article, we’ll explore how recirculating cooker hoods work, what their advantages are and how to install them in your home.

Key Takeaways

  • Recirculating cooker hoods use carbon and grease filters to clean air before recirculating it, making it more energy efficient than ducted hoods.
  • They do not require external ducting or ventilation systems and take up less space, making them easy to install without major structural changes.
  • Regular replacement of filters suited for specific models is important for efficient operation.
  • Energy rating, decibel rating, fan speed, lighting options, and installation instructions are all important considerations when selecting and installing a recirculating hood.

Design and Technology

Recirculating cooker hoods are a great example of modern design and technology, making life easier for cooks everywhere! Cooker hoods come in all shapes and sizes, allowing them to be integrated into any type of kitchen. They bring many benefits such as improved efficiency when cooking, cost savings due to not having to install an extraction system, and lower noise levels. In addition to this they also help reduce the potential for grease build-up on surfaces near the cooker.

To achieve these beneficial results recirculating cooker hoods use two types of filters; carbon filters which absorb odours that are produced during cooking, and a grease filter which collects grease particles from the air before recirculating it back into the kitchen. This is done through fans that draw up air from the hob area and pass it through both filters before releasing it back into the room.

The effectiveness of recirculation hoods depends heavily on their extraction rate – how much air volume they can move within a certain amount of time – however with some careful selection you can ensure your system meets your needs while still being efficient and cost-effective.

Ducted vs Recirculation

Ducted and recirculating cooker hoods differ in the way they filter and remove airborne grease, smoke, and odors from kitchens. Ducting is a more common approach to doing this; extraction hoods, chimney hoods, and wall-mounted models are all examples of ducted cooker hoods. While these types of cooker hoods have variable fan speeds, allowing for greater control over air circulation, they require exterior ducting to expel the bad air outside. Alternatively, there are also recirculating options which involve a ductless hood that uses filters to clean the air before re-circulating it back into the kitchen.

When comparing the two types of cooker hoods side by side, one can see that recirculation is often considered a more energy efficient option because there is no need for external ducting or ventilation systems. Additionally, these types of extractor fans tend to take up less space than their traditional counterparts because they don’t require any extra fittings or accessories that come with using an outlet pipe outside. Furthermore, some recirculating options can be easily installed without having to make any major structural changes like cutting into ceilings or walls.

Ultimately though, when deciding between a ducted versus recirculated cooker hood it comes down to personal preference as well as practicality; factors such as budget constraints and existing infrastructure will help dictate what type of system is best for each individual situation.

Extraction Rate

The extraction rate of a cooker hood determines how quickly it can remove grease, smoke, and odors from your kitchen – whether it’s ducted or recirculating. An extractor hood with an efficient extraction rate is key to a successful kitchen design. Extractor hoods are available in both ducted and recirculation cooker hood models, each having their own advantages. The rate of extraction for a ducted cooker hood varies greatly depending on the type of fan used and how efficiently it is maintained. Generally speaking, these types of cooker hoods have higher extraction rates than any recirculation model due to their ability to vent air outside the home through an external wall or roof vent.

Recirculation cooker hoods are typically more energy efficient because they don’t require additional ventilation systems. They use two fans – one for intake and another to push filtered air back into the room. These types of extractor fans generally have lower rates of extraction than their ducted counterparts but still work effectively enough to remove cooking odours from the kitchen area. Recirculation models often come with touch-sensitive controls that allow you to adjust the speed according to your needs. They’re also often made from stainless steel for durability and aesthetics, making them great additions to any kitchen design .

In comparison with other types of extractor fans, recirculation cookerhoods offer convenience and cost-efficiency without compromising on performance when it comes to removing air pollutants like smoke, grease and odours from your kitchen area. With its sleek design and energy efficiency features , this type of appliance is increasingly becoming popular among homeowners looking for an effective solution for keeping their kitchens smoke-free .

The Filters

Eliminating cooking odours from your kitchen is made easy with recirculation cooker hoods, which come equipped with powerful filters for trapping unwanted air pollutants. The filter helps to capture grease, smoke and other particles as they are drawn into the hood from the cooking surface. Depending on the type of filter used in the recirculating hood, there may be a need for regular replacement to ensure its efficiency.

When selecting a recirculation cooker hood, it is important to consider the energy rating as well as the decibel (db) rating of the extractor fan. For instance, an Extractor Fan that has an A-rating for energy consumption and 57db rating will prove more efficient compared to one with lower ratings. Additionally, if you have a kitchen island or venting hobs installed, then you should opt for a higher extraction rate than what would typically be necessary for traditional hobs.

Replacement filters can easily be sourced online and through retailers selling kitchen appliances; however, it is important to make sure that you purchase one that is suited for your specific model of recirculating cooker hoods. A good quality filter can help keep your kitchen free from odours and smoke while also reducing maintenance costs associated with replacing them regularly!
