Ductless Range hoods are a crucial part of any modern kitchen, as they assist keep air quality at a secure level. They are doing that by sucking in most of the emissions released during cooking and leading them through an airway duct that vents to the surface

While most exhaust hoods vent air out of the house, some remove harmful agents and odors by filtering them, instead. Those are called ductless range hoods.

But what exactly may be a ductless hood? Why would you like it rather than a ducted unit? And what would be the simplest ductless hood right now?

What Are Ductless Range Hoods?

Rather than extracting air, ductless or non-ducted range hoods recirculate air. Recirculation improves air quality around the cooking area by cleaning and redistributing it.

As with exhaust hoods, recirculating hoods use a lover to suck in the air alongside harmful pollutants. But rather than leading the air outside, they clean it by running it through degreasing filters and charcoal carbon filters then returning it to space.

Since ductless hoods don’t remove air from the kitchen, they don’t require ventilation ductwork, which suggests you’ll save tons of your time, effort, and money. You furthermore may don’t got to sacrifice storage space for the air passage.

Ducted vs. Ductless Range Hoods

There are a couple of key differences between ducted and ductless vent hoods.

1. Configuration

Ducted range hoods need ducting to figure, and that they have both top-venting and rear-venting configurations. Top-venting systems run a duct from the highest of the hood to the ceiling; rear-venting systems, on the opposite hand, run from the port within the back and lead the duct through the wall.

Ductless range hoods, on the opposite hand, don’t have a venting configuration because they don’t extract; they simply filter the air before blowing it back to space.

Convertible hoods— hoods that are both ducted and ductless— have both venting configurations also as seats for the charcoal filters (not always included). These hoods easily switch back and forth between ducted and non-ducted settings.

2. Features

Non-ducted range hoods generally have lower suction than their ducted counterparts. But they’re also less noisy. Air-recirculating hoods are usually marked around 180 CFM (cubic feet per minute).During this time most routes can easily be hooded at 500 CFM.

The cost of a ductless hood and its installation is more forgiving, because it doesn’t require ductwork to function. With no ducts to put in, the installation process is quicker and takes less effort.

Most single-purpose non-ducted hoods are installed beneath the cupboard above the cooktop. Convertible (sometimes called ducted/ductless) hoods, which may be found out for either a vented or recirculation system, are more flexible. They provide more ways to mount the hood, including under-cabinet, wall, and island (ceiling) mounts.

3. Effectiveness

Where the air quality within the kitchen cares, ducted hoods are simpler because they pull all the odor and fumes out of the kitchen and replace the contaminated air with fresh, clean air.

However, that replacement of air can create problems in the weather. When warmth is precious, you would like to stay the maximum amount of air indoors as possible. That’s when non-ducted hoods are valuable. Because ductless hoods simply recirculate the air in your kitchen, the warmth loss is minimal.

In short, if you would like quality breathing air while cooking, getting an air passage is that the thanks to going. But if you don’t want to feature an air passage or if you’re concerned about heat loss, a ductless, filtered system can still deliver decent results.

Ductless Range Hoods (Buying Guide)

Keep these details in mind when buying a ductless range hood:

1. Effective Area

As a rule of thumb, a hood should be a minimum of an equivalent or one size bigger than that of the range. For instance, a 30-inch range should have a 30-inch or 36-inch hood. The rule ensures that the hood of choice has enough coverage to capture all of the emissions from the cooktop.

With hoods installed on the kitchen island, professionals recommend one size (6 inches) larger. The additional coverage compensates for the shortage of a back wall, which helps limit air movement.

2. Filters

Carbon filters are crucial to ductless hoods. They assist purify the air by trapping odors and invisible pollutants, but they don’t last forever.

You’ll get to replace your carbon filters two or 3 times a year— more regularly if you’re cooking is frequent or particularly smoky. You’ll usually economize by buying replacements in bulk.

3. Suction

In comparison with ducted hoods, ductless units have weaker blowers, even the simplest ones. Their powering ratings stay around 200 CFM. If you’re wondering why the suction is so low, it’s intentional. Because ductless hoods filter and redistribute air instead of extracting it completely, they require less power.

While tons of suction may be a definite advantage, it’s not a transparent indicator of performance for non-ducted units; the effectiveness of the filtration system is arguably more important.

4. Price

A recirculating hood rarely sells for quite $100, because of the low power rating and economical build. Ductless convertible units, however, cost about an equivalent as ducted exhaust hoods: up to around $400 with high-end models.

Their suction rating is similar and approximately 190 to 190 CFM. The series features a compact, under-cabinet body frame and works best when installed 18-20 inches above the counter.

Models during this series use aluminum mesh filters to degrease smoke and other cooking emissions. Added charcoal carbon filters help lookout of odors and fine particles.

Cleanup and Maintenance

You can remove, clean, and reuse the aluminum mesh filters, but they’re going to eventually got to get replaced. Aluminum wares usually don’t enter dishwashers. So unless the manufacturers say they’re dishwasher-safe, you ought to clean them by hand using warm water, mild degreasing soap, and bicarbonate of soda.

The charcoal filters aren’t as resilient because of the meshes and wish more regular replacement. They will stay effective for as long as 6 months, or about 120 hours of cooking, and they’re not reusable.

These hoods also wear a spot-resistant coating. To wash it, all you would like to try to do is wipe the outside with a humid cloth.

2. Cosmo 5MU Series Ducted/Ductless hood – Top Best Ductless Range Hood

Ductless Range Hoods in 2021

As a brand within the hood market, Cosmo has grown in popularity in recent years, and therefore the Cosmo 5MU series has two of the brand’s bestselling convertible or recirculating-optional hoods. The models feature chrome steel construction, an option for recirculation, and a relatively high CFM rating.

Slim and Convertible

This convertible series from Cosmo may be a suitable pick for many modern kitchens. It comes during a slim, chrome steel body that goes right under the cupboard or hangs off the rear wall. The series has two models: the 5MU30, which is 30 inches wide, and therefore the 5MU36, which is 36 inches.

Controls are push-buttons. At top speed, the hood draws air at around 200 CFM. That’s sufficient power for a recirculation hood. For exhaustion, it’s less impressive: 200 CFM can lookout of no quite 20,000 BTU. A typical power burner on a gas stove gives about 15,000-17,000 BTU. So if you’re using quite one among those directly, this hood may leave a number of the emissions behind.

To run the recirculating setup, first, switch the lever on the fan to the air recirculating mark. This makes the hood release the air through the front gaps, not through the air passage. Then, install the charcoal carbon filters for the fan.

Unfortunately, because these two Cosmos come as ducted extraction hoods by default, the carbon filters (code CFK4) must be bought separately. Inserting a charcoal filter into the facility blower is sort of simple; you’ll find the instructions within the product guide.

Degreasers and Carbon Filters

The 5MU30 and therefore the 5MU36 accompany two and three mesh degreasing filters, respectively. These mesh filters, though aluminum, are processed so that it’s dishwasher-safe on low-heat cycles. Even so, manual wash-up is that the thanks to going if you would like to maximize the lifespan of any aluminum wares.

Mesh filters are often cleaned and reused for up to 2 years. Charcoal, on the opposite hand, should be changed once every 6 to 12 months.

Under-Cabinet Mount

The cabinet mount design helps make the installation process much quicker. Venting options contain both up- and rear-venting; both take 5-inch round ducts, and there’s no adapter included for rectangular outlets.

You’ll have a damper, also called a backdraft regulator that helps prevent air from entering through the ductwork. Just in case you would like to modify from rear- to top-venting or the other way around, there are seal caps that you simply can use to seal up the opposite openings.

The manufacturer recommends keeping the cooking surface above 24-26 inches.


Admittedly, Cosmo models 5MU30 and 5MU36 aren’t the simplest range hoods available, but they’re great options if you assail a convertible design. They’re worth keeping in mind, to mention the smallest amount.

The series is under a 5-year warranty.
