Air Quality In Cars Needs Regulation

Experts have called for the regulation of car air conditioning systems after new trials revealed that popular models are letting in dangerous amounts of pollution.

Safety tests on 11 types of car have shown huge variation the the ability to purify incoming air, exposing those inside to millions of poisonous particles with each breath.

The Toyota C-HR performed worst, blocking out just 1 per cent of pollutants, while the VW Polo managed only 35 per cent and the Ford Fiesta 40 per cent. However, the Mercedes E-Class was able to purify 90 per cent of the incoming air, demonstrating that the technology exists to substantially protect passengers.
