On your car’s dashboard, you’ve probably spotted a button with an icon of a car and a rotating arrow inside. Sound familiar? That’s the air recirculation button. It might seem like a small and inconspicuous feature, but it’s important for your comfort—and even your safety. However, using it incorrectly can lead to unexpected issues. Here’s what you need to know.
What is this button really for?
The air recirculation button simply prevents outside air from entering the cabin and circulates the air already inside the car. Essentially, your vehicle runs in a closed circuit, where the air you’re breathing is continually heated or cooled by the car’s system before being redistributed through the vents.
It might seem trivial, but this feature deserves a bit of attention.
When should it be activated? Specific situations
Here are the times when using the air recirculation button can be particularly useful:
- In highly polluted areas (such as heavy traffic on a busy road).
- When there are bad smells outside, like near farms or treatment plants.
- While passing through tunnels or areas with a lot of dust.
- During hot summer days to make the air conditioning more efficient.
Caution: Avoid using it under certain conditions
However, during winter, it can be problematic. Why? Because continuously recycling the same air raises the humidity inside the cabin. This can lead to:
- Fogging up of your windows and windshield, making it harder to see clearly.
- A build-up of CO₂, which can cause headaches, fatigue, and discomfort.
- An environment conducive to the growth of mold and bacteria, which are harmful to your health.
These issues can sneak up on you, and without realizing it, you could be compromising your safety. You might think you’re improving comfort, but you could be doing the opposite.
