Over time, nanoparticles’ chemistry has shown exceptional ability to solve a wide range of problems in various fields, including the control microbiological air quality buildings. Herein, magnesium ferrite (MgFe2O4) was synthesized using coprecipitation, then characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET), scanning electron microscopy (SEM), Transmission Electron Microscopy (TEM) and photoelectron (XPS). MgFe2O4 nanoparticles were assessed for their inhibit Escherichia coli ATCC 8739 growth airborne bacterial viability laboratory atmosphere through direct filtration system. The material showed strong inhibitory activity against E. by eliminating practically all viable cells tested suspensions after 1 h contact time presence light. Finally, prepared setup revealed that passing bacteria non-woven fabric filters impregnated with effectively eliminates them. Thus, only colony-forming unit (CFU) obtained from 36 L filtered air, while filter (without MgFe2O4) allowed passage 2.6 × 105 CFU liquid medium. results initiate potential applications controlling indoor (IAQ), especially healthcare facilities where microbial resistance antibiotics is most notable, individuals are exposed, contamination risks highest.
