Introduction: In kitchen decoration, range hood is one of the indispensable household appliances.
Faced with a wide variety of range hood products on the market, consumers often have a hard time making a choice.
Especially when choosing the exhaust air volume of the range hood, the two values of 21 cubic meters and 23 cubic meters often make people hesitate.
This article will give you a detailed analysis of the actual use needs, performance differences, etc., to help you find the most suitable range hood.
1. Analysis of the concept of exhaust air volume
Exhaust airflow refers to the volume of air that can be sucked away by the range hood per minute, measured in cubic meters per minute (m3/min).
The larger the exhaust airflow, the better the smoking effect of the range hood.
At present, the mainstream range hood on the market has two exhaust air volumes: 21 cubic meters and 23 cubic meters.
Second, the performance difference between 21 cubic and 23 cubic range hoods
1. Smoking effect
Theoretically, the smoking effect of a 23 cubic range hood is better than that of a 21 cubic range hood.
Because the exhaust air volume is larger, the smoking speed is faster, and the fumes can be prevented from spreading more effectively.
But in actual use, the difference between the two is not obvious, especially for home cooking, the 21 cubic range hood is enough to meet the demand.
2. Noise
The larger the exhaust airflow, the higher the noise of the hood.
Therefore, the noise of a 23 cubic range hood is usually a bit louder than that of a 21 cubic range hood.
If you are sensitive to noise, it is recommended to choose a 21 cubic range hood.
3. Energy consumption
The higher the exhaust airflow, the higher the energy consumption of the range hood.
Therefore, the 21 cubic range hood is relatively better in terms of energy consumption, and is more energy-saving and environmentally friendly.
3. How to choose the right range hood for you?
1. Cooking habits
If your home cooking method is mainly light and produces less oil smoke, then a 21 cubic range hood is enough to meet the demand.
If your cooking method is mainly stir-frying and frying, and there is more oil smoke, you can consider choosing a 23 cubic range hood.
2. Kitchen area
When the kitchen area is large, it is recommended to choose a 23 cubic range hood with a large exhaust air volume to ensure the smoking effect.
If the kitchen area is small, the 21 cubic range hood can also meet the demand.
3. Budget
The higher the exhaust airflow, the higher the price of the hood.
If you have a limited budget, you can consider choosing a 21 cubic range hood.
4. Noise sensitivity
Noise-sensitive users are advised to choose a 21 cubic range hood to reduce kitchen noise.
Fourth, summary
Based on the above analysis, we can conclude that under the premise of meeting the needs of home cooking, 21 cubic range hoods are enough to use.
If you have higher requirements for smoking effect, you can consider choosing a 23 cubic range hood.
However, it should be noted that the larger the exhaust airflow, the better, and it needs to be selected according to individual needs and actual conditions.
When choosing a range hood, in addition to paying attention to the exhaust air volume, you can also consider other factors, such as brand, appearance, function, etc.
