Using the dust from vacuum cleaner bags to detect hidden fungal growth indoors

The study endeavours to establish a more reliable and less intrusive sampling approach for the initial assessment of hidden fungal growth using fine dust from domestic vacuum cleaner bags. As a continuation of a broader study, five bags are tested using DNA and enzymatic analyses and complemented by culture-based identification. The findings indicate that fine dust from vacuum cleaner bags is a promising sampling technique. This could lead to the development of a streamlined inspection protocol, mitigating costs and minimising disruption for occupants.
