Post-Diwali Smog: How to Manage the Air Inside Your Car

1

Keep the windows up in smoky traffic, check that the cabin filter is correctly fitted and use recirculation while passing through smoke.

Can an air freshener remove smoke pollution?

Fragrance can cover a smell without removing the pollutant causing it. Avoid adding scent to diagnose an odour problem; inspect the filter and ventilation system instead.

Should I run the engine in a garage to clean the cabin air?

No. Exhaust can accumulate in enclosed spaces. Never idle the car in a garage to run its fan or air conditioner, even with the garage door open.

Will a new cabin filter stop every firecracker smell?

No. Filter performance varies, and particle filters do not remove all gases. A remaining smell does not by itself establish how much pollution is present.

Do electric cars need cabin filters too?

They can have cabin filters just as combustion-engine cars do. Check the handbook for your model rather than assuming that the absence of exhaust means clean cabin air.
