The range hood is one of the essential appliances for our kitchen. It helps to remove the smoke, greases, or odors from your kitchen. There are different types of range hoods available in the market.

Let’s talk about more what is a ductless range hood 

The ductless or recirculating range hood is one type of range hood, which also has a fan like a ducted but not vented duct. Ductless range hoods do not come equipped with pipes or ducts to funnel airborne particles away from the kitchen. Instead, they’re designed with powerful exhaust fan units to remove smoke and dirty air and then blow it out to the space. They employ a recirculation method to improve interior air quality. It has various types of filters for cleaning the air from the kitchen and provides the air. Sometimes we also recognize it as a recirculating range hood. 

The ductless range hood is more flexible than any other range hood. It can be placed anywhere. It is also easier to adjust the size of your cooking canopy while you are doing an overhaul of your kitchen. But, you might have to change your charcoal filter that is activated at least every two or three times each year to boost the effectiveness of the hood of your range.

The primary difference with a ducted range hood is that instead of the air becoming exhausted and escaping to the outdoors, it goes through a filter and then recirculated back to the kitchen. As we told you before, recirculating range hoods or ductless range hoods work precisely the same way as a ducted range hood. A lot of people don’t know that the majority of ductless range hoods are able to be transformed to be used as ductless. All you need to do is buy the filter that has charcoal layers.

Vents for exhaust are typically located near the upper part of the hood or to the side of the hood. When you use your range hood, you’ll feel the air escaping back into your room.

How do ductless range hoods work?

What is a ductless range hood?

A range hood’s primary goal is to remove smoke, odors, and steam. When you cook, that creates lots of gases. It also removes grease/oil (heat) and dangerous gases from your kitchen. The steam and the oil/grease that is released when you cook are stuck on the grease filters and then taken away. 

The process typically involves heated air repeatedly scurrying by passing through the mesh or the baffle filter. This causes the grease and steam to condense and then separate. 

The actual process will depend on the type of grease filter in the first place: baffle or mesh. The charcoal filters serve to catch odors. In contrast to grease filters, charcoal filters can’t be cleaned and must be replaced. 

For most people, the principal reason for installing a ductless range hood in their home is to get rid of cooking smells and stop them from spreading throughout the home. To avoid these, most people prefer to keep an open window. It’s therefore essential to note charcoal filters are essential to remove the smell, and depending on their usage. These types of filters need to be replaced every three months. If you don’t cook frequently or you cook often, you might need to replace it only one time every year or less. 

How to install a ductless range hood? 


Range hoods offer a reliable way to cut down on smoke, steam, vapors, and other gases caused by cooking. A ductless range hood operates by pushing air that is contaminated by a carbon filter in order to remove it. Before starting any electrical work, ensure that you turn off the power supply to the proper circuit by switching off the breaker in the service panel at your home.

Before installing the ductless range hood, you should measure the distance from the fans assembly and cooktop. The distance may differ between 24 to 36 inches for an average installation. 

Installation process

Range hoods are attached to the cabinet using screws to mount them. The screws are typically about 1/2-inch long, meaning they are not able to enter the interior or the inside of the cabinet. The knockout plug, which is removed from the rear of the range hood, comes with an electrical connector before installation. The appliance is secured in position while the wire is passed through the connector, and then followed by mounting screws, are installed. When the range hood is secured to the bottom of the cabinet, then you can connect the wires from the hood to the neutral. For the final step, replace any covers and then install the filters.

Some considerations before installing a range hood

  • The range hood is an electrically wired appliance that requires a 110-volt power source to run the appliance. While it’s not essential to add a dedicated circuit for the appliance, you don’t need to overburden existing circuits as well. If you intend to tap onto an existing circuit, you must calculate the load that will be placed on the circuit to ensure that the added load of the range hood doesn’t overburden the safe capacity of the circuit. If a suitable power source isn’t readily available, you should hire an electrician to build an electrical circuit.
  • Range hoods can be mounted on the top of the kitchen cabinet that is located above the stove’s surface. Modern homes have cabinets that have dimensions that allow accommodating a range hood’s installation, but older homes might not. It is necessary to determine how thick the hood is before including the minimum height requirement to determine if you have enough space. If not enough clearance is available, you’ll have to modify the cabinet. This may mean taking down the cabinet to make room for a modification or to raise it up to allow for the height required.
