Sampling sites for fungal isolation (A) and fungal population (B) on the air cleaner high-efficiency particulate air (HEPA) filters obtained from the three atopic dermatitis-inflicted child patient's houses. Sections 1, 2, and 3 indicate the top, middle, and bottom areas of the HEPA filter used for fungal isolation. The mean separation was calculated using Duncan's multiple range test, with p < 0.05. The presence of identical letters above the bars implies no significant differences in the fungal population among the sampled sections of the HEPA filters. CFU, colony forming unit.
