If you don’t have much space in your kitchen, and you’re left with an under-cabinet space for a hood, then your best bet becomes a ductless range hood.

Although it won’t suck the air out of the kitchen as ducted range hoods do, a ductless range hood will still capture the odors and smoke particles in the air, helping you thereby to a cleaner kitchen.

In this ductless range hood review, you’ll get a list of the top hoods in the market, plus a buying guide to help you make the best choice.

What to Check Before Buying Best Ductless Range Hood?

Following is a closer look at the important features of a ductless range hood that you need to understand and pay attention to if you want to get the best ductless range hood for your kitchen.

1. Size

It’s important that your range hood matches the size of your cooktop, so it can function effectively. This is based on the laws of physics.

Range hoods pick particles suspended in the air as they drift upwards but if the range hood is too narrow or small, the particles might drift away to other parts of the kitchen as they rise and therefore, not get filtered by the hood.

This makes it necessary to measure and know how much space you’ve got under the cabinet and how large your cooktop is. You’ll then have to do the maths.

For best results, the hood should be at the very least, equally wide as your cooktop, or in simple terms, the bigger the hood, the better.

2. Filter

Unlike ducted range hoods, which just draw the air away from the kitchen to the outdoors, ductless or recirculating range hoods draw air from the kitchen and blow it over a filter that captures the particles in it and the hood then releases the air back into the kitchen.

This filter will usually contain activated charcoal particles, which trap the odor, grease and smoke particles in the air and allows much cleaner air to get recirculated into the kitchen.

You’ll need to clean or change the filter about once or twice each year to keep a ductless range hood working efficiently, else you’ll start to get yellowing of the walls around your cooktop.

3. Air Flow

Airflow is a measure of how much air passes through the hood in a given time-frame and it’s usually measured in CFM, which stands for Cubic Feet Per Minute.

Naturally, the higher the CFM rating of a range hood, the better it should work, but you should note that filter quality is also important in determining how effectively a ductless range hood works.

Since ductless hoods need to pass their air through a filter, they tend to offer lower CFM ratings than their ducted counterparts, but this isn’t everything, what matters here is how many particles actually get filtered.

4. Noise

Hoods need a blower to drive the air with the particles in it and these blowers make noise. Secondly, larger or faster blowers, which generate higher CFMs of air are naturally louder.

So, if noise happens to pose a problem for you, you may want to consider premium hoods with added sound dampening features to keep noise at low levels while blowing large volumes of air.

5. Fan Speeds

Two or three-speed settings is enough and offers you the opportunity to either choose a higher fan speed when normally cooking or to choose a slower speed after you’re done with cooking and you need to continue ventilating for a little longer.

6. Price

Range hoods can cost anything from a hundred dollars to many thousands of dollars depending on style, construction materials, size, and of course, features.

What you need to do here is to set your budget based on what you can comfortably afford and then focus on only those offers that fall within your budget.

​Ducted vs Ductless Range Hoods

You may wonder if choosing a ductless range hood is the right decision or if a ducted system could be better for you. One thing you should understand is that they each have their advantages and disadvantages and following is a look at these two types:

1. Ducted Range Hoods

Ducted range hoods need a duct connection that drives air from the kitchen to the outdoors, effectively ventilating the kitchen by drawing fresh air into it.

This carrying away of the smell and carbon particles from the kitchen through a duct is what differentiates the two types of range hoods.

Ducted range hoods are more limited during installation than ductless hoods because you’ll need to connect it to a duct. They also take up more space than ductless hoods and the installation can get very costly if you don’t already have ductwork in your home.

On the brighter side, ducted range hoods are often more efficient because they don’t need to filter the air at all, but to just vent it outdoors.

2. Ductless Range Hoods

With ductless range hoods, you get an air filtering system that is much easier to install and that needs less space as well, since they do not need a duct network to work.

Ductless hoods simply draw your kitchen air and blow it over a filter, which traps the smell and carbon particles from the air and releases cleaner air into the kitchen.

By releasing the air back into the kitchen and by not filtering steam, a kitchen with a ductless hood will often get humid. Power consumption and sound levels are often higher as well.

In the end, the decision between these two types of range hoods lies with you because you’ll need to choose based on your circumstances, which can include budget, available space, taste, kitchen design, and infrastructure.

How To Clean a Ductless Range Hood?

A properly functioning ductless range hood offers you many advantages, so it’s necessary to keep its filter clean by periodically washing it. Even the best ductless range hood will become ineffective when not cleaned after months of use.

Following is a step-by-step guide to cleaning your range hood’s filter.

Step 1. Get Ready

Your first step is to get ready for washing your ductless range hood’s filter by preparing hot soapy water in the right container. The water should at best be boiling or very hot and the container into which you pour it should at best be heatproof like a sink or something else.

Once you’ve poured the water into the container, add some degreasing dish soap and some baking soda and mix well for best effect. The water is now ready for the filter and you also need to keep a brush handy.

Step 2. Remove the Filter

Most manufacturers try to make it easy to remove their range hood’s filter but as you can imagine, their systems will vary slightly from one another.

This makes it necessary to either take a quick look at the user’s guide or try to figure it out by yourself. For most, you just need to slide it after opening a latch or something similar.

Step 3. Soak It

Next step is to soak the filter in the hot soapy water and to let it soak for a while, the longer the better. Let it soak for at least 10-15 minutes to loosen the grease from the filter and make it easier for you to scrub off.

If the filter is too large for your hot water container or sink, then try soaking one half of the filter at a time.

Step 4. Scrubbing the Filter

Once the filter has soaked enough and you can even see that the grease has changed color, it’s now time to scrub the filter using a brush. Try to use a non-abrasive brush or one that can reach into tiny slots and crevices for a proper cleanse.

Step 5. Rinse & Dry

When you’re satisfied with how clean the filter has become, remove it from the soapy water and rinse it well to remove all the remaining grease and soap, then dry it with a towel.

Step 6. Replacement

Now that your range hood is clean and shiny, it’s time to put it back. It pays here to remember if there was any special procedure when removing the filter, so you can just follow it and make sure it fits well.


We’ve reached the end of this ductless range hoods review and you’ve seen the best offers in the market, including budget offers and those that offer only the best features.

If you’re in a hurry, you can easily pick the best overall range hood here, the Broan 413004​ which is available in five sizes.

For a more stylish offer, the Cosmo 5MU30 should do, with its smooth design, 3-speed fan, and 200 CFM wind speeds.
