This is EXACTLY when you should and should never use the recirculation feature on your car aircon

An Australian parenting group has revealed the exact times to use the air recirculation feature on your car’s air conditioning – and warned it should be avoided in the winter. 

Mum Central shared the tip to their Facebook page with hundreds of parents commenting to say how useful it was. 

When used correctly, the air recirculation button cuts off the outside air to the inside of the car.

However, using the recirculation button in the winter can be dangerous as it can trap hot air inside the car and make the inside of the vehicle humid.

This can lead to foggy windows that reduce visibility on the road and make the car too warm, which can lead to drowsiness and falling asleep at the wheel. 

It’s even more important on long road trips as fresh air is necessary for staying alert. 

‘Most all vehicles have a recirculation button with the AC controls in their cars. But many of us are unsure when to use it,’ Mum Central shared in a now-viral post.

‘Well, the easy answer is to use it in the summer and turn it off in the winter. 

The post explained if your car has been ‘baking in the sun’ its better to roll the windows down and turn recirculate off for the first minute or so to get rid of the super hot air inside the car before turning the recirculate on (stock image) 

‘The recirculation button simply takes the air from inside the car and recirculates it in the cabin instead of pulling fresh air from outside. 

‘On hot days, if you do not recirculate the cooler air in the cabin, then your AC system is pulling hot air from outside and trying to cool it. 

‘Using the recirculation feature will get your car cooler and will decrease the wear and tear on your AC system’.

They added if your car has been ‘baking in the sun’  its better to roll the windows down and turn recirculate off for the first minute or so to get rid of the super hot air inside the car before turning the recirculate on.

The post – which originally came from  Tyrrell Auto Centers in Wyoming – went on: ‘Any time you are stuck in traffic (summer or winter) be sure to use the recirculate. 

‘If you are pulling air from outside, then you are pulling in all the pollutants and carbon monoxide from all the traffic. Studies show that recirculating your AC can cut down on the pollutants entering your vehicle by 20 per cent when stuck in traffic’.
