Atmospheric pressure air plasma is an attractive technology because it is easyto set up and handle, cheap, and safe. In this paper, a brief review on air plasma configuration and the results of air plasma is presented. One of the important propertiesof any plasma treatment is the generation of reactive atom species such as oxygen(O), nitrogen(N) also known as RONS, and other ions molecules particles. Air plasma has been found to have the same effect when treating surfaces. Surface modification, hydrophilicity, and decontamination effect were observed when materials are exposed to air plasma. The advancement of air plasma technology will improve the surface processing technology by reducing its operating cost.
