[Abstract] Air pollution is one of the main environmental and health hazards in several countries, which affects children under 5 years of age and adults aged 50-75 the most. The World Health Assembly approved the WHA68.8 resolution in 2015, in which air quality guidelines were defined in order to achieve sustainable development. Some of the main regulated air pollutants are PM<sub>10</sub>, PM<sub>2.5</sub>, NO<sub>2</sub>, O<sub>3</sub> and SO<sub>2</sub>. Hence, this article covers the characterization of the photocatalytic reaction efficiency of two polymer solutions, which use TiO<sub>2</sub> as photocatalytic active [1] in different substrates for its potential application as primer or paint [2]. A Sampling Conditioning Unit was used in order to prove that the pollutants such as NO<sub>x</sub>, SO<sub>x</sub> and CO<sub>2</sub> decrease when the solutions are applied. Additional tests were performed in SEM (Scanning Electron Microscope), to measure the adherence quality of the paint to the substrate, and later analyze changes at the altered surfaces with added solutions [3]. The results presented a decrease of 47.8% on CO<sub>2</sub>, and 30.7% on SO<sub>x</sub> at constant flux.
