The programme features particle filters and combination filters and are made to the same specification as original equipment. The filters contain up to five layers, trapping almost 100% of pollutants and particles. Manager Paul Payne comments: “We recommend that every cabin air filter should be replaced at least once a year, every 10,000 -15,000km, or as specified by the vehicle manufacturer, to ensure optimum efficiency and hygienic air quality.”

No special tools are required to install them and a replacement should take fifteen minutes.
