The filters operate in conjunction with the air conditioning systems.
Over 5,000 buses of the Mercedes-Benz and Setra brands now have the multi-layer, progressively constructed high-performance filters on board as a retro-fit. The buses include those plying urban routes, touring coaches and long distance scheduled buses.
They include an anti-viral functional layer that filters out up to 99 percent of the aerosols in the interior.
A clearly visible sticker in the boarding area identifies vehicles with this equipment in which the air can be completely renewed in one to four minutes.
In addition, Daimler Buses is also offering driver-protection doors with fully glazed partition walls made of safety glass or polycarbonate for new vehicles and as a retrofit solution.
