This paper proposes and analyses the design, fabrication, and evaluation of Nano-Lungs — a wearable personal air purification system that integrates graphene-based nanofilters with an Al driven  air  quality  monitoring  and control platform. The proposed device aims to provide mobile, high-efficiency removal of airborne particulate matter (PM1.0, PM2.5, PM10), volatile organic compounds (VOCs), and biological contaminants while continuously monitoring environmental and physiological parameters. The work synthesizes recent advances in graphene nanomaterials, filter fabrication methods, micro-blower and power management                                 hardware,             low-power environmental sensors, and edge Al techniques for pollutant classification, anomaly detection, and adaptive control. We present materials and methods for producing graphene oxide (GO) and reduced graphene oxide (rGO) filter media, integrate multi-layer filter architectures, detail the electronics and firmware for sensing and actuation, and propose experimental protocols for laboratory and field testing. Results from bench- top experiments, computational fluid dynamics (CFD) simulations, and prototype testing are discussed. Safety, biocompatibility, lifetime, and ethical considerations are examined.

The paper concludes with suggestions for future work and pathways toward regulatory approval and commercialization. Air pollution is a major global health concern, leading to respiratory diseases cardiovascular problems, and reduced life       expectancy.
