Abstract
A new simplified method for monitoring the concentration of air-borne fungi has been developed. By using the new method, field measurements in 73 bed rooms in winter and 71 living rooms in spring were conducted to identify the reliability of this method for untrained conductors. The results showed that about 60 % of the measured samples passed the quality check, e. g. the travel blank. Also it has been identified that the measurement by this simplified method was adequate enough to show the category in European guidelines which is based on measurements by air-samplers.
