Air pollution in Qatar, driven by excessive air pollutants and marked by high Carbon Dioxide (CO₂) emissions, leads to respiratory illnesses. An experimental design was conducted to test the filtration efficiency of Spent Coffee Grounds (SCGs) and Date Palm Fibers using an ESP32 microcontroller to monitor air quality changes. The results showed that Date Palm Fibers reduced pollutants by 28.95%, activated SCGs by 34.85%, and their combination by 41.07%. The ESP32 sensor demonstrated a quick response time of 2.42 seconds and detected pollutants within a 5 cm range. This system effectively combined real-time monitoring with sustainable filtration, highlighting the potential of organic waste in improving air quality. It significantly reduced ppm levels and proved effective in air quality monitoring. Further improvements could be achieved by enhancing filtration using Zinc Chloride (ZnCl₂) or Phosphoric Acid and optimizing airflow for greater efficiency and reliability
