Air quality in buildings is often controlled by various Heating, Ventilation, and Air Conditioning (HVAC) systems. These systems are equipped with air filters to reduce dust and aerosol load in the air. Ambient aerosol particles may contain different organic matter such as pollen, bacteria, and fungi. In warm and humid indoor air conditions, the presence of such air particles may result in the growth and transmission of infectious bacteria, fungi, and mold spores.
