Indoor air quality in classrooms is one of the key aspects of educational building design, as it has a direct impact on the physical health, comfort, an‎d academic performance of students an‎d staff. Studies conducted in various schools indicate that despite the use of diverse ventilation methods, no optimal solution has yet been achieved for this challenge. The aim of this research is to identify the most economical an‎d effective strategy for improving classroom air quality.To this end, a comprehensive review of recent studies on passive approaches to reducing indoor pollutants was conducted, examining different adsorbent materials an‎d functional coatings, including photocatalysts, metal oxides, metal–organic frameworks (MOFs), zeolites, silica, layered double hydroxides, an‎d activated carbon. Subsequently, a proposed material was synthesized in the laboratory, giving the research both a theoretical an‎d an experimental dimension.This material was eva‎luated based on criteria such as cost, compatibility with different climatic conditions, an‎d suitability for educational environments. The results revealed that no single material can provide a complete solution; however, a strategic combination of materials tailored to classroom conditions (including climate, number of students, lighting, humidity, an‎d ventilation) can significantly improve indoor air quality. Such an approach can pave the way for healthier, more cost-effective, an‎d more efficient learning environments.
