Does AC make you ill, how much fuel does it use, does it spread bacteria? MSG Equipment looks at five common beliefs about car air conditioning.
MSG Equipment examines common beliefs about car air conditioning and stresses that most problems stem from misuse and lack of maintenance.
- Illness: lowering the temperature gradually, not aiming airflow at people and keeping windows closed with AC on reduce the risk of colds.
- Harmful vapours in the cabin: the article says regular ventilation easily prevents this.
- Bacteria: condensate and dirty filters can breed germs; regular cleaning and filter changes are essential.
- Fuel: AC raises consumption by about 10%, but driving with open windows can add even more.
- Fatigue: dry air may cause drowsiness; airing the cabin on long trips helps.
It also notes that accident risk rises markedly once cabin temperature exceeds 27°C.
