The article delivers the research results on content of particulates in passenger compartments in the course of driving in urban settings and results of assessment of air cleaning with serial and specially designed cabin air filters. It has been established, that particulates air pollution in passenger compartments in operating conditions is high and dangerous. There is no ecological standards on efficiency of air cleaning in passenger compartments. Thus, the vast majority of cabin air filters are ineffective in dealing with particulates that are less than 1-2 microns, which are the most dangerous for humans. It has been experimentally proven that efficient cabin air cleaning for limiting the content of the particulates that are less than 1-2 microns is technically feasible by means of particular air cleaning ecosystems, which allows justifying development of new ecological standards for “environmentally friendly vehicles”. https://www.biotech-asia.org/vol12no2/research-on-content-of-particulates-in-passenger-compartments-of-motor-vehicles-in-operating-conditions/ Motor vehicles; eco vehicles; passenger compartment; air pollution; particulates; tire wear; cabin air filter; ecological standards
