Question 5483
If you suffer from a respiratory allergy, it is advisable to...
- drive with the windows open.
- not use the outside-air ventilation, unless the vehicle has a pollen filter.
- drive with the air conditioning on very high if the vehicle does not have a pollen filter.
Show answer and explanation
Correct answer: not use the outside-air ventilation, unless the vehicle has a pollen filter.
If you have a respiratory allergy, it's best to keep outside air out, because it carries pollen. So don't use the outside-air ventilation unless the car has a pollen filter, and keep the windows closed. Run the air conditioning on a low setting.
