It is important to remember that using the recirculation feature for extended periods can decrease the air quality inside the car, so it’s best to use it in short periods and switch back to fresh air mode periodically.
In this article, we will discuss the benefits of using circulating air in a car and when to use it for optimal results.
What Is Circulating Air In A Car?
Circulating air in a car refers to the process of recycling air from inside the vehicle rather than taking in fresh air from outside. It is also known as recirculating air. This feature is commonly found in modern cars, either as a manual or automatic setting.
The purpose of this feature is to maintain the temperature and air quality inside the car.
How It Works?
When circulating air is activated, the air conditioning system pulls air from within the car and circulates it throughout the vehicle. Instead of taking in outside air, the system recycles the air inside the car and prevents it from escaping.
This process keeps the inside air at a constant temperature, as the hot or cold air is continually circulated.
Moreover, recirculating air has several benefits that include:
- Reducing dust and allergens from outside air
- Saving fuel consumption as the air conditioning unit does not have to work as hard
- Reducing the amount of exhaust fumes and air pollution from outside the car entering the cabin
However, there are certain instances when it is recommended to turn off the recirculating feature and take in fresh air from outside. These situations include:
- Driving in heavy traffic, as the build-up of carbon dioxide inside the car can affect the driver’s concentration
- When there are unpleasant smells inside the car, such as when transporting pets or smoking in the car
- When the air quality outside is fresher than inside the car, such as when driving in rural areas with clean air.
Therefore, using the circulating air option in your car can be beneficial but knowing when to turn it off can be crucial for your health and safety.
