Indoor Air Quality (IAQ) describes the characteristics of the indoor conditions, a climate within an enclosed building, and in relation to occupants’ health and comfort. There are many factors of indoor contaminants, one of them being bioaerosol. The most common bioaerosol is mold, a type of fungi.

Enclosed environment which more people spend their leisure time at such as at the child development centers, gymnasium, cinema and shopping malls.
