A filter system is presented which allows the reduction of the concentration of ultrafine particles in vehicle cabins to very low levels. The original ventilation system is switched to the recirculation mode and all cabin intake air is supplied via a retro fitted filter system. Tests with a variety of different vehicles (from passenger cars to coaches) show the efficiency of the system. Number concentration of particles inside and outside a car, the nanoparticle filtration system, fllter-efficiency: transmission for the new filter and for the filter loaded to apressure drop of 2.9 mbar, setup of the filter with integrated prefilter for course particles and blower, prototype of the filter system, main filter, prefilter and blower are included the system operated by an external control box, containing the drive electronics for the blower and displays for filter pressure drop and time meter, filter pressure drop as function of operating time in a highly polluted road tunnel, a possible solution to mount the filter system, particle concentration inside and outside the car (passenger car), concentration drops to very low levels, particle concentration inside and outside a passenger car with the filter turned on, two nanocleaner filter systems mounted in a school bus, filter system for buses installed in the luggage compartment are presented in the paper.
