How Does A Ductless Range Hood Work?

A ductless range hood uses charcoal filters to clear the kitchen air from fumes, grease, odor, etc., without using ductwork. It circulates the filtered air back into the kitchen and gives you a fresh environment for cooking.

Ductless range hoods work by sucking the greasy and unhealthy kitchen air through filters and recirculating fresh air. The carbon filters trap dirt and remove intense kitchen odors as the air crosses throughout. As a result, ductless range hoods freshen up your in-house ventilation.


Ductless hoods may be installed anywhere. The filter comprises carbon and charcoal, which helps eliminate bad odor and harmful smokey substances from the air, which can be returned through the kitchen.

The working of a ductless range hood is similar to a ducted one but with a slight difference. Instead of the air getting passed outside directly, it goes through a mesh or sieve and then flows back into the kitchen.

In a ducted range hood, the fans are placed outside to pass the polluted air and recirculate the fresh air.

It is crucial to know that ducted range hoods can easily be converted into ductless hoods by attaching a coated filter with a charcoal surface. So we can say that ductless range hoods are perfect for places where there is no scope of having a ducted one.

Yes, they are quite effective in filtering amounts of smoke and cooking odors. However, they do not filter out steam, so one can use them in homes, not commercial places.

If you have a ductless range hood, it slightly becomes easy to clean or change the activated charcoal mesh once a year. For effective and long-term use, you probably need to wipe out  and replace the filters from time to time
