The exhaust system plays an essential role in both the aesthetics and functionality of the kitchen. They filter the air, eliminating grease and vapors, ensuring a cleaner environment without unpleasant odors. However, choosing the ideal option can be a challenge.
To help you with this decision, we present 5 essential tips for finding the ideal exhaust system and keeping your kitchen well ventilated.
Most modern kitchens have an extractor fan, an essential piece of equipment to ensure a continuous flow of fresh air, contributing to hygiene and air quality.
1. Main types of exhaustion
Exhaust systems are divided into three main categories: exhaust with outlet to the outside, recirculation exhaust and recirculation exhaust with natural AIR.
-
Exhaust with outlet to the outside
This system completely removes smoke and odors by directing air out of the kitchen through pipes. It is the most widely used solution for air renewal, although it can generate a little more noise and requires an outdoor installation. -
Recirculation exhaust
In this method, fumes and odours are filtered by an activated carbon system before the purified air is returned to the room. Since it does not require an outlet to the outside, installation is simpler. However, air purification is a little slower, as the air needs to pass through the filters repeatedly until it is completely clean.
Furthermore, maintenance of this system is more frequent, with it being recommended to replace the activated carbon filters every three months. -
Recirculation exhaust with natural AIR technology
Without the need to go outside, this system stands out for its high efficiency in eliminating odors, reducing them by up to 95%.
Natural AIR technology removes viruses, bacteria and allergens with 99.9% efficiency, ensuring a healthier environment. This technology has a 10-year durability without the need for maintenance, only requiring periodic cleaning of the metal filters.
2. Suitable dimensions
The size of the extractor hood or chimney must be compatible with the size of the hob or stove. To ensure efficient extraction, the width of the equipment must be equal to or greater than that of the hob. The ideal height for installing the most traditional extractor hood is 65 cm above the hob or stove or between 150 cm and 170 cm in the case of ceiling systems.
3. Extraction power
Choosing a model with the right power for your kitchen size is essential to ensure efficient ventilation. To calculate the ideal power, use the following formula:
📌 m² x Height x 8 = m³/h
In other words, multiply the kitchen area by the ceiling height and the ideal number of air changes per hour (8). For ceiling extraction systems, an air flow of 8 cycles per hour is recommended.
4. Noise level
All exhaust models generate some noise, but it is possible to minimize this impact by choosing a model with low decibel (dB) levels. For kitchens that also function as living spaces, a noise level of less than 65 dB is recommended, ensuring greater acoustic comfort.
5. Additional functions
The most modern models offer extra features that make use more practical and efficient. When choosing your equipment, consider features such as:
-
Auto power off / Timer: optimizes energy consumption;
-
Filter cleaning indicator: alerts you when cleaning is required;
-
Perimeter suction: improves efficiency in capturing smoke and odors;
-
LED lighting: provides better visibility and a more welcoming environment.
Choosing the ideal exhaust fan for your kitchen not only improves air quality, but also contributes to a more functional and modern space. In addition to design, it is important to evaluate the features and functionalities that best suit your needs.
