Year long monitoring of indoor aerospora in Thiruvananthapuram was conducted. This was compared to the results obtained in a simultaneous outdoor air monitoring. It is concluded that indoor aerospora was not a real reflection of outdoor concentration of pollen and fungal spores. Fungal spores and house dust mites are the major constituents of the indoor aerospora whereas pollen grains form the major component in outdoors.
