This research addresses many grand challenges that face Egypt: reducing pollution, reducing and adapting to the effects of climate change, working to eradicate public health issues and diseases, and recycling and retaining garbage for recycling. Air purification systems emerged as crucial to mitigate the negative effects of air pollutants. The purpose of the study is to deal with the increasing levels of pollutants in Shubra El-Khima homes, including particulate matter (PM) and criteria pollutants, using local recycled waste. First of all, research about different purification methods was done, including activated carbon, photocatalysis using TiO2 coating, and particulate air filters from plastic fibers. After that, the chosen solution is to construct an air purification system that includes a prefilter and the three methods as stages that target specific pollutants. Then, the air purifier has been constructed using treated and recycled waste materials, and the design has been tested. Finally, the major findings are that the prototype has achieved the design requirements, reducing the total amount of pollutants by 89.08%, and further the CO specifically by 82.82% in nearly 5 minutes. Furthermore, the iodine number of activated carbon was 354 mg/g. In brief, the prototype could withstand a high concentration of pollutants of 11001 ppm. To sum up, the major conclusions are that the project is effective, eco-friendly, and sustainable, representing a solution for the specified problem.
