The Effect of the State of the Indoor Environment on the Air Quality in
the Cabin

Air quality affects the state of the environment, human health as well as individual ecosystems to a significant extent. The permissible level of air pollution is determined by the national laws of each country and the EU. Air quality problems are related to the amount of pollutant emissions that escape into the atmosphere. These emissions have different origins. Transport is identified as one of the serious problems of the future also in terms of air pollution, especially in view of the rising trend of final energy consumption in road transport. One of the main factors of deteriorating air quality in the urban environment is burdened by high traffic density. Regulation of emissions from transport, including passenger cars, is in the general interest of European legislation. Transport produces almost a quarter of Europe's greenhouse gas emissions and is a major cause of urban air pollution. At the same time, it is necessary to deal with air quality in cars, which is affected by several factors. The aim of this article is to analyse the air quality in the cabin of a car that uses a pollen filter with activated carbon. The analysis is focused on particles from 0.3 to 10μm in 16 size categories that affect the health of people in the car. The influence of the fan setting and the state of the indoor environment on the particle concentrations will also be evaluated.
