The forced air flow sampling method was used to investigate microorganisms in the air conditioned indoor environments. In the investigated 50 samples, the concentration of microorganisms was in the range of 28-333 CFU/m 3. The bacteria were found more than the fungi. G positive bacteria were the dominant. The coagulase positive Staphylococcus had a detection positive rate of 78% in the samples. The dominant fungi species were Penicillium, Cladosporium, Aspergillus and yeast. The dominant bacteria were Staphylococcus, Micrococcus and Bacillus. The CFU, especially fungi CFU, in the indoor spaces was less than the outdoor air. The respirable and non respirable viable particles in the indoor air were collected and counted respectively. It was found that respirable viable particles had a higher percentage in indoor air than outdoor air. High concentration of microorganisms was found in fibrous insulation material and condensed water in the air duct. Gnegative bacteria, which can survive for a long period, was the dominating type in the condensate samples.
