Air-filtering bus to launch across six regions in the UK

Nitrogen oxide emissions from Bluestar bus, trialled in Southampton, are less than a diesel car

An air-filtering bus which removes pollutants from city streets while it operates is to be rolled out into six regions of the UK following a successful trial.

The bus, trialled since 2018 in Southampton, is fitted with fans on the roof that draw in air at a rate of one cubic metre per second and filter out ultra-fine particulate pollution.
