Currently, many Brazilian kitchens still operate without range hoods or with inadequate systems. As a consequence, The room retains a constant smell of food, and the walls accumulate an invisible film of grease. e, Over time, mold appears easily.
However, when properly sized, a range hood completely transforms the kitchen experience. In this scenario, The air remains clean, and odors do not persist. e The walls stay clean for much longer.
Throughout this article, you will understand how range hoods work, what types are available, how to correctly size them for your kitchen, and the costs involved. e, especially if it's really worth the investment. At the end, With this, you will know exactly which range hood to specify for each situation.
What is a range hood?
In simple terms, a range hood is an exhaust device responsible for removing stale air, steam, and odors from the kitchen, directing them to the outside through a duct.
In practical terms, it works like an "air vacuum cleaner". I.e, The equipment sucks in air contaminated with smoke, vapor, and grease. e, Then, he throws him out of the building.
Main Components
Every range hood is composed of a few essential elements. Among them, Among the highlights are:
- Campanula: visible part above the stove
- Engine: responsible for suction
- Filter: retains particles and fat
- Duct: It conducts air to the outside.
- Anti-reflux valve: It prevents the return of outside air.
Basic Operation
When the range hood is activated, the process occurs as follows:
- Initially, the engine starts to rotate.
- Next, a depression forms in the bell.
- The contaminated air is sucked out.
- Subsequently, it goes through the filter.
- After that, it goes up the duct.
- Finally, it is expelled to the outside.
As a result, The kitchen becomes free of stale air in just a few minutes.
Why is a range hood important?
Although many people associate range hoods solely with comfort, this perception is incorrect. In practice, The equipment offers direct benefits to health and cleanliness. e to the durability of the kitchen.
1. Respiratory Health
During food preparation, various contaminants are released, such as:
- Fat particles
- Carbon monoxide (in gas stoves)
- Nitrogen oxides
That way, The range hood reduces these harmful agents, thus decreasing respiratory problems. 40 to 60%. Especially, This benefit is particularly relevant in households with children or elderly people.
2. Cleaning the Walls
Without a range hood, the oil suspended in the air settles on the surfaces. Over time, This creates dirt, stains, and a proliferation of germs. On the other hand, With a suitable range hood, the walls stay clean for much longer.
3. Mold Prevention
In addition to grease, excessive moisture promotes the growth of mold. In that regard, The range hood quickly removes steam, preventing future problems.
4. Odor Elimination
Without proper ventilation, the smell of food will linger for hours or days. Although, When the range hood is properly sized, odors disappear in a few minutes.
5. Kitchen Durability
Accumulated grease accelerates the deterioration of paint, metals, and furniture. Consequently, As a range hood wears down, the lifespan of the kitchen decreases. With a range hood, this wear and tear is reduced by... 70 to 80%.
Types of Range Hoods
Currently, there are several types of range hoods, each suited to a specific situation.
1. Traditional Wall-Mounted Range Hood
In the first place, is the most common model.
Advantages:
- Good efficiency
- Affordable price
- Simple installation
Nonetheless, requires ducting through the wall.
2. Cooktop Integrated Range Hood (Downdraft)
This model stands out for its design. However, However, suction from the bottom up is less efficient.
Like this, It is recommended when visual appeal is a priority.
3. Countertop Range Hood (Extractor Fan)
In this case, the system recirculates the filtered air. Therefore, It does not completely eliminate odors.
Even so, It's a good solution for small spaces.
4. Built-in Cabinet Hood
This is a sophisticated solution. Although, This requires custom-made carpentry and a larger investment.
5. Benchtop Air Purifier with Filtration
Finally, this is the simplest solution. Nonetheless, However, its efficiency is limited and the filter requires frequent replacements.
Correct Sizing
More important than the type is the correct sizing. Otherwise, If the range hood fails, it will not fulfill its function.
Basic Formula
Flow rate (m³/h) = Length × Width × Height × 10
Like this, A kitchen measuring 3 x 2 x 2.5 m requires approximately 150 m³/h.
Range Hood Installation
The installation follows well-defined technical steps. Firstly, The positioning is defined. Right away, The electrical part is being prepared. After, The duct and filters are installed. e, Finally, the tests are carried out.
Is it Worth Investing in a Range Hood?
Direct answer: Yes.
Although there is an initial cost, the benefits in health, cleanliness, and durability are significant. e Property appreciation quickly pays for itself.
On average, the return on investment occurs between 3 and 6 years old. After this period, the gain is continuous.
Conclusion
In short, the range hood is no longer a luxury item. Today, It is an essential piece of equipment in any modern kitchen.
Therefore, if your kitchen doesn't have a range hood or uses an unsuitable model, it's worth reconsidering. The return in comfort and health is significant. e Durability is immediate.
