How To Install A Ductless Range Hood
The range hood is i of a working kitchen'southward most common yet overlooked components. People often forget that they fifty-fifty have a kitchen range hood, let alone worry nearly how it works. However, if yous do any amount of cooking, you lot'll desire a working kitchen exhaust fan, of which there are two basic types: ductless and ducted.
A ductless range hood is besides known as a ventless range hood, and they work past filtering and recycling air within your kitchen. Rather than having a vent outside your habitation, a ductless range hood utilizes a carbon or charcoal filter to purify the air. Ductless models are a great alternative to ducted hoods if y'all're tight on space or don't have access to an outside wall.
This article will expect at how a ductless range hood works and if they're effective. We'll also interruption downwardly essential maintenance tips and whether or non you'd be better off installing a ducted range hood. Let'southward get cooking!
Check out our best ductless range hoods, but it'southward important to understand how ductless range hoods work.
How Does a Ductless Range Hood Piece of work?
Ductless range hoods go by several names, including ventless range hoods and recirculating range hoods. Rather than conveying dingy air exterior of a kitchen via a vent, ductless range hoods have a series of filters that purify the air and and then recirculate it. Ductless range hoods are also an effective means of removing the smoke wafting in the air.
While vented range hoods are oftentimes preferred, there's a place in the working kitchen for ventless ones. Allow'south go through a stride-by-step process of how ventless range hoods work.
- The range hood usually gets installed in a higher place a stove, oven, or grill. Many kitchens just take one range hood, but you lot can have every bit many. Multiple range hoods are essential in restaurants and other settings with multiple cooking appliances.
- As you are using your kitchen appliances, they typically release smoke, steam, grease, and other debris into the air. If you are creating smoke and other harmful chemicals, it'southward essential to take your range hood turned on to get rid of it.
- The ductless range hood has a fan inside it that sucks air into the hood.
- Carbon or charcoal filters within the recirculating hood likewise filter out cooking odors, fume particles, debris, and other contaminants from the air. The fan sucks muddied air into the filters, capturing and absorbing the pollutants.
- The clean air gets released after passing through the filters and circulates back into the kitchen.
This last stride is the main difference between a ducted range hood and a ductless one. Where a ducted range hood has a vent on the back or top of information technology that carries dirty air outside of the house or building yous're in, a ductless range hood cleans the air and releases it back into the kitchen.
Ducted hoods also don't have carbon or charcoal filters inside them because in that location'southward no indicate in cleaning the air that gets ejected from the building. They will accept a baffle or mesh filter that covers and protects the fan motor and blocks about cooking grease.
Modern ductless hoods accept stainless steel bamboozle filters reminiscent of those inside commercial kitchens. Bamboozle filters are the best pick for a ductless system because the baffles are dishwasher safe.
Ventless hoods are unsuitable for gas stoves requiring a ducted model to remove cooking exhaust and comply with local building codes.
Noise Levels of Ductless Range Hoods
Dissonance levels are measured in decibels. The noise level of the ductless kitchen hood volition vary based on fan speeds. Decibel levels will vary based on the fan ability within the ductless vent hood.
The highest fan speeds have the highest decibel levels. Cheap fans usually accept 2 or 3 fan speeds. More expensive fans can accept half-dozen or more than speeds.
The consensus is that a range hood with a noise level of twoscore decibels on the lowest and merely 65 decibels on the highest setting is considered an ultra-quiet range hood.
Some range hoods measure audio in sones. A sone is a unit of loudness or the subjective perception of sound force per unit area.
To convert Sones to dB, we utilise the post-obit equation:
dB = 33.2×log10(Sones) + 28
You may meet noise levels in sones instead of decibels. To convert decibels to sones, you lot can use the equation:
Sones = ten((dB-28)/33.2)
Most range hoods operate effectually 6 to 10 stones on the highest setting.
For a frame of reference,
- 1 sone: the sound of a refrigerator humming
- Two sones: a quiet office or some other professional environment
- Three sones: a TV playing at a comfortable book
- Four sones: a typical conversation betwixt ii people
- Five sones: a louder, more agile conversation
- Half-dozen sones: a quieter restaurant setting
- Vii sones: light traffic
- Viii sones: the average sound of traffic
- Nine to ten sones: congested traffic sound
The chart below shows the Sones to decibels conversions, but you can too cheque out the Sones to dB calculator.

| Sones | Decibels (dB) |
|---|---|
| 1 Sone | 28.00 dB |
| 1.5 Sones | 33.85 dB |

What does CFM Mean?
CFM is an acronym that stands for cubic feet per minute. It is a measurement unit that describes a range hood'southward airflow rate. The CFM rating of a range hood tells you how much air information technology can move in one minute.
Virtually range hoods have a CFM rating between 150 and i,000. The size of your kitchen and the type of cooking you lot practise will determine the CFM rating you lot need. The larger the cooking surface and your cooking habits volition oftentimes dictate the size and CFM y'all demand.
For case, if you accept a modest kitchen and do lite cooking, you may only need a range hood with a CFM rating of 150. But if yous take a large kitchen and do heavy cooking, you may need a range hood with a CFM rating of 1,000.
Almost bones under chiffonier range hoods have about a 250CFM rating. An ultra-high CFM range hood would be 900CFM or higher.
When shopping for a range hood, be certain to compare the CFM ratings of different models to find the one that is best suited for your needs.
The width (size) of the hood and the bodily CFM tin can be much dissimilar. For example, you can take a broad hood to match your range size aesthetically but internally have a small fan motor that doesn't move much air.

It's of import to note that not all modern range hoods are convertible. Typically, you lot must purchase ane with the specific design to alter from ducted to ductless simply by calculation a filter. While yous tin can besides go from ductless to ducted, this is less common.
What Kind of Filter Does My Ductless Range Hood Need?
Ductless range hoods accept an internal filter responsible for catching and absorbing contaminants in the air. There are commonly two sets of filters included in the ductless venting process. The get-go line of defense is a set of mesh or baffle filters that capture some of the larger particles.
The second set of filters is the activated charcoal carbon and mesh filters. Mesh filters (grease filters) trap grease in mesh material. Charcoal filters trap grease and neutralize strong cooking odors.
They are an excellent option for capturing big grease particles in the mesh filter. They besides soak up grease, smoke, fat, and other contaminants floating in the air. These filters also capture most of the fume or steam floating in the air just can't catch all of it.
How to Properly Maintain My Ductless Range Hood
Properly maintaining your ductless range hood is an integral part of its operation. Ventless range hood filters work similarly to how the filter on your furnace works. As air passes through, the filter traps and absorbs contaminants and gets dirty. The dirtier the filter gets, the less effective it becomes. Here's how to maintain your ductless range hood.
- Wipe downward the surface of your range hood using acetone or a glass cleaner.
