Is A Kitchen Vent Necessary? Simple Advice for You

The kitchen is one place where gases, smoke, and smells tend to build up. In this area, kitchens need to have ventilation grilles that work with natural airflow and air from extraction ducts.

In kitchens, smoke removal is an absolute must.

As one of the places that make the most smoke, the place where we cook food, whether at home or in a commercial kitchen, needs a way for the smoke to go outside. So, yes, the kitchen vent is important. Ventilation in the kitchen is something that needs to be thought about in depth. This way, we can keep smoke from getting into the air.

In the case of industrial or business activities, a smoke outlet system to the outside must be put in place. The rules about smoke extraction make it clear that a smoke extraction system to the outside is needed to make sure that the air inside is safe to breathe.

The said industrial regulation says that service premises must have an exhaust air flow rate of at least 2 dm3/s per m2 of floor space. For air extraction, spaces like kitchens or parking lots are considered to have a very high level of contamination.

In kitchen ventilation, the way to get rid of grease, smoke, and smells in the air takes the lead. And it’s a very sensitive thing since we don’t have these extra problems in other parts of the house or in other places where we work.

What should ventilation and extractor fans do in a kitchen?

They have to get rid of the fumes that come from cooking right in front of where the fumes are coming from. The extractor should be as close to the cooking area as possible.

The extractor needs to be at least as big as the stove where the food is cooked that gives off smoke.

Ventilation in a kitchen must get rid of too much hot air and bring in clean, cool air. This is important to keep the environment healthy.

The ventilation system must also be able to get rid of the stress and lack of comfort that comes from a place that doesn’t have enough airflow, as well as the dangers that come with this.

The movement of air must not make you feel bad or uncomfortable.

It has to get rid of the carbon monoxide buildup and stop fires from starting on their own.

Also, it should be simple to clean. A blocked exhaust system will make the car less efficient and make it more likely that a fire will start by accident.

For it to be more comfortable, it needs to be free of noise and vibrations that hurt us.

In homes, a kitchen extractor fan is something that most homes have. But kitchen extractor hoods are usually not checked in private settings. They must also be chosen based on a set of rules.

There are many things we can do at home to improve the airflow in our kitchens:

As we’ve said before, the space for getting the smoke out must be bigger than the space for cooking. If not, it won’t be able to take in all the smoke that is made.

The air must be made fresh again. Many kitchens have a window close by, and if there are no other ways to let air in, opening the window can help.

We can put lids on the pots and pans so they don’t leak air outside.

Systems that use ceramic hobs are faster and safer than those that use gas or electric resistance.

The path the smoke takes from the extractor to the outside must be very short.

People call the kitchen a “wet room.” We must keep your space in great shape and avoid problems with humidity.

But we need mechanical ventilation systems in our kitchens to make sure the air is always fresh. What else can we do to improve our health and protect ourselves from the smoke the best?

Where should vents go?

For better airflow, the ventilation grilles need to be placed in different parts of the house. So, the intake grilles will go at the top of the windows, and the exhaust grilles will go on the ceiling.

A straight route to the roof is preferable when we are confronted with a single-family dwelling. For good airflow in every room, you should cut at least 1.5 cm off the bottom of the doors so that the stale air can escape. But if the home is smaller, the solution is to install two ventilation grilles at different heights. One will be less than half a meter from the ground, and the other will be more than 1.80m above the ground, in the highest part of the wall.

It’s important to put in both ventilation grilles, because if we only put in one, the room will be ventilated, but not in the right way because air will be coming in and going out at the same time.

Kitchens mechanical ventilation systems

When we talk about large industrial kitchens, installing a mechanical ventilation system becomes more important. In these situations, it is important to make sure that fresh air comes in and that the air in the room is refreshed.

Dual-flow ventilation is the best way to do this at home or in an industrial setting. This makes it possible to automatically get rid of smoke and stale air in all rooms and the kitchen. The same system is also in charge of bringing filtered and fresher air back into each room to make it feel new again.

As we’ve already said, kitchens need good ventilation because they are humid places where smoke and pollution are made. We need to be able to get rid of smoke and stale air to protect the health of the people who work or live there. This will not only keep the air fresh, but it will also keep bad smells and uncomfortable situations from happening at home or work.


The vents let the air flow in and out on their own. This air circulation is crucial for keeping our house fresh and comfortable by preventing musty aromas from settling and allowing excess moisture to evaporate. People often think that these grilles aren’t needed when gas installations or boilers are added, but they serve a purpose and shouldn’t be taken away.

Kitchen vents or ventilation grilles are easy to use and operate, allowing fresh air to flow into the house via the ducts located in the kitchen, bathrooms, and bedrooms. Then it leaves through the bathroom or kitchen, which are the rooms with the most moisture.
