Extraction is when the stale air is extracted out of the room through ducting in an outside wall to the air outside. Recirculation is used when it is not possible to duct out through an outside wall. The air is sucked into the hood, filtered, purified and pumped back into the room.
Although extraction hoods are more effective than recirculation hoods, they are more expensive to install due to all the extra requirements. A recirculation hood pushes the air up through filters inside, which then remove any moisture and smells before the air is then reintroduced into your kitchen.
Recirculating cooker hoods are unable to remove steam or moisture caused by cooking, but they can still effectively remove grease and cooking odours improving the environment in your home if you are unable to fit an extraction hood in your kitchen.
What Is a Recirculating Cooker Hood? A recirculating cooker hood sucks up and cleans the air from your cooker and then pushes it back into your kitchen. An extractor cooker hood forces all of this air, smells, and things out of your home.
Do bathroom exhaust fans have to be vented outside? Yes, it is always a good idea to have your bathroom exhaust fan vent outside. Remember, the purpose of your extractor is to remove moisture from the air. If you simply deposit it in another room or attic, you are potentially just moving the problem to another area.
Yes. A recirculating range hood works beautifully, the same way as a ducted range hood. The main difference is that rather than the air getting exhausted to the outside, it passes through a filter, and then recirculated back into the house.
Recirculating will mean the air is passed through the filters to capture grease and smells. It is repeated until the hood is turned off. In most cases a vented hood is preferable, however a recirculating option will remove smells.
In short – yes, you do need an extractor hood. Since April 2006, building regulations state that extract ventilation must be fitted in a kitchen which has been built from that date onwards. A kitchen will meet these regulations if the unclean air is extracted externally.
Do I need a recirculating kit for my range hood? Ducted hoods do not require recirculating kits since your kitchen air moves through ductwork to the outside of your home. Recirculating range hoods recirculate your kitchen air without a kit, so you don't need one for those either.
Ducted extractors remove air entirely, down a stretch of ducting to outside the home, propelled by a motor placed just outside or just inside the building. Air is taken through a grease filter, which traps fats, whilst odours, fumes and condensation are expelled outside.
PVC ducting is the cheapest one available, but is highly versatile and can be used in the majority of general ventilation connection applications, including cooker hoods.
There are two different types of cooker hoods and the difference between them is what they do with the air from your cooking: extraction hoods pump the air outside, whereas recirculation hoods filter it and circulate it back into your kitchen.
The hood is positioned in an inadequate location
Any units close to the hood will accumulate condensation and obstruct the air circulation around the hood. This will lead to condensation building up and water dripping/running down, and will almost certainly cause damage to your units into the bargain.
Ducted extractors need access to an external wall so that air can be removed from the building via a pipe (or duct) to the outside.
A typical recirculating kit is comprised of carbon filter, clamps, deflector, and mounting material. The carbon filters absorb dirt and other odors extracted from the air in the kitchen. Clean air is blown back into the kitchen through a vent after all the air impurities have been absorbed by the carbon filters.
Strictly speaking, you don't need an extractor fan over an induction hob or any other hob, actually. However, an extractor fan is a fantastic way of getting rid of smells, smoke and steam while cooking. You can buy induction hobs with built-in extractors as well.
If the bathroom is part of a new build or a new extension, then yes, you will need to include an extractor fan to comply with UK building regulations. Even if you have a window that can be opened.
Rental homes must have openable windows in the living room, dining room, kitchen and bedrooms. Kitchens and bathrooms must have extractor fans. Mould and dampness caused by poor ventilation is harmful for tenants' health as well as landlords' property.
There is no requirement that your Over The Range (OTR) Microwave be vented to the outdoors. All OTR microwave ovens can be set up to either allow the fan to recirculate the air back into the kitchen or be vented to the outdoors.
KEY TAKEAWAYS: Convertible vents offer improved air quality by venting air outside of the kitchen. They can also convert into a ductless system that uses air filters. Recirculating microwave vents send your kitchen air through a series of aluminum, carbon, or charcoal filter vents.
While a recirculating filter isn't as effective as other types of microwave venting, it still clears your kitchen of the most pungent cooking odors. In addition, countertop models usually have a recirculating vent, but some built-in microwaves share the same filtration.
A ductless (or ventless) range hood does not vent out of the home, instead, it carries the debris and smoke form the air and filters it through a charcoal or carbon filter before releasing it back into the room. While many times this method is not as functional as a vented hood, it does work.
We don't recommend venting your gas stove with a ductless hood. A ductless range hood merely recirculates your kitchen air. The air moves into your hood through charcoal filters and back into the kitchen. A ductless range hood can't get rid of a lot of the ultra-fine particles that are harmful to your health.
