A versatile air purification system is disclosed herein. The invention harnesses reflective light trapping components capable of circulating high-intensity visible and infrared radiation. Passing air absorbs a part of the energy in aerosols as viruses and bacteria. Excessive energy consequently induces denaturation of biomacromolecules and can trigger chemical and physical disinfection mechanisms to airborne pathogens. This technology is also compatible with various HVAC systems, like those of medical facilities, buildings, and vehicles, and can be utilized for other fluids too. The system can further be applied as a distinct, portable air purification apparatus.
