Do I Need a Recirculating Kit for My Hood? There is no need for installing recirculating kits in ducted range hoods since unwanted air from the kitchen is vented to the outside. Ductless range hoods filter the air in your kitchen without the need for a kit as they are designed for the same purpose.
Recirculating range hoods recirculate your kitchen air without a kit, so you don't need one for those either. But if you want to convert your hood from ducted to ductless, you'll either need a kit, charcoal filters to attach to your blower, or both.
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.
The most obvious way to determine if your range hood is ductless is whether or not you have ductwork. If you have no ductwork, your hood recirculates kitchen air. Also, if your vent hood comes with carbon filters or a recirculating kit, it is ductless.
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.
Unvented range hoods do filter some grease and cooking odors from the air, but the general consensus is that they're nowhere near as effective. Nor do they remove heat and humidity, so they won't help keep your kitchen cool while you cook.
The Recirculation Hood
Recirculation/self-circulating cooker hoods are often much cheaper than extraction hoods because they don't include ducting. However, they are less effective at dealing with smells, grease, and smoke because they have to process the air, and inevitably they don't do that 100% perfectly.
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.
The major difference between the two is that a ductless range hood, which is more common in most kitchens, uses a fan or blower motor to pull all the grease and smoke out of the air, then recirculates it. A ducted range hood, on the other hand, vents all the bad air straight to the outside.
Range hoods can be recirculating with stainless steel mesh or baffle filters. To make your hood recirculating, you need charcoal filters as well. These sit inside your range hood blower and trap grease and odors produced from your cooking. Then, that air moves back into your kitchen.
A recirculating kit is used in a range hood when venting to the outside is impossible or not desirable. It can convert ducted range hoods to ductless so that warm air from the kitchen can be filtered and recirculated back into the room.
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.
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.
What is this? Carbon filters aren't necessary if your cooker hood uses extraction to remove odours and dirt outside. However, if your cooker hood uses air recirculation, carbon filters will help to remove cooking smells and keep your kitchen fresher and cleaner.
A non ducted or ductless range hood is not the best option for gas stoves because they work by filtering the air inside the hood and returning it into the kitchen. Even if you have a hood with a high CFM rating, charcoal filters will not capture all the gas produced by the stove.
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.
Across the United States, the majority of residential homes cooking with gas do not need to vent their range. However, just because you don't have to does not mean that you shouldn't. If you use a commercial-style range, then you will be required to do so.
Do I Need a Charcoal Filter for my Coffee Maker? If the water you are using to brew coffee is not filtered, you should use a charcoal filter to remove chlorine residues to prevent chlorine's corroding effects on the internal parts of the coffee maker.
Depending on the type of range hood you have, this air may be cleaned and recirculated or extracted to the exterior of your home. Without a range hood and its filters, your kitchen would be in pretty bad shape with grease on the countertops, cabinets, and floors.
What is the Difference between an Activated Carbon Filter and a Charcoal Filter? The primary difference between a water filter that uses activated carbon and one that uses charcoal is in the filtering materials themselves. Both are hard, porous substances that capture contaminants.
Range hoods do not have to be vented to the outside. You can purchase hoods without ductwork called ductless hoods. But, ducted range hoods are almost always preferred over ductless hoods.
