The objective of this study is to control the air quality parameters for a selected range of different particulate matters. A comprehensive experimental approach is established to regulate the quality of air about a selected range of different air pollutants being investigated in the indoor atmosphere of the church building. Relative humidity, temperature, carbon dioxide, particulate matter and radon were considered as the factors of air quality extents. For establishing the association among the selected parameters, the data were mathematically analyzed. The correlation coefficient confirmed a strong relationship between the indoor CO2 level and the number of public. A negative relationship between the indoor CO2 extent and indoor temperature confirmed that due to the increase in temperature the concentration of CO2 decreased as well. A solid adverse connection among indoor relative humidity and indoor air temperature showed that due to the increase in air temperature, the level of the relative humidity decreased. Some recommendations were proposed for the treatment of air quality in church buildings for human well-being.
