Does CFM Matter for Ductless Range Hoods?

Cooking can be a daunting task for any home chef, but having the right tools to make it easier helps. One essential appliance in any kitchen is a range hood; they are absolutely vital when it comes to removing cooking odors, steam, and smoke from your kitchen. But do you need to pay attention to CFM when choosing a ductless range hood? In this article we will explore the answer to this question – so read on to find out more!

What is CFM in terms of general range hoods?

CFM is an important metric when it comes to range hoods as it refers to how powerful the fan is. The higher the CFM rating, the more air it can move per minute – making your range hood more efficient and effective at removing smoke, odor, and grease from your kitchen.

How do you know what CFM is right for your home? The answer depends on several factors, such as size, layout, location in the home and personal preference. As a general rule of thumb, larger rooms require more cubic feet per minute of airflow than smaller ones. You also need to consider where your vents are placed in relation to each other – if they’re too close together or too far apart, this could affect the performance of your system.

Does this CFM also matter for ductless range hoods?

Ductless range hoods have become increasingly popular in modern kitchens due to their convenience and sleek designs. If a homeowner wants an effective and efficient kitchen ventilation system, it is important to understand the importance of CFM ratings, that you know. But when it comes to ductless range hoods, does this CFM matter?

CFM stands for “Cubic Feet per Minute” and is the measure of airflow that a range hood can produce. So a ductless range hood is also designed with the same CFM rating in mind. A 400 CFM ductless range hood means it can pull 400 cubic feet of air in 1 minute. In this respect, the calculation is the same. But there is a little problem, that is in another place.

Then what CFM should I go with ductless range hood?

I have given a link for CFM if you read it or already know then this CFM matter will be more clear to you. However…

In the case of ducted range hoods, these range hoods send smoke and grease directly out of the kitchen through a duct. So if it’s a 400 CFM range hood, it’s pushing out a total of 400 cubic feet of air.

But in the case of ducted range hoods, these range hoods do not send the air outside the kitchen but filter the air through a charcoal filter and recirculate it inside the kitchen.

In this case, since the air is not venting, the range hood is pooling 400 cubic feet of air, but some of it is being forced back into the kitchen. So 400 cubic feet of air pooling would seem less than a ducted range hood even if it has the same power and pulls the same amount of air.

So, I will suggest, if a 400 CFM ducted range hood is proper for you then you go with 500/600 CFM for a ductless range hood.


CFM is an essential factor to consider when deciding on a ductless range hood. CFM determines the amount of air movement and ultimately how well it will perform in exhaust mode. While you may be tempted to choose a higher-powered model, it’s important to think about the size of your kitchen and the noise level you are comfortable with. With this in mind, take your time researching before making a decision to find the best solution for you.
