The article presents the results of developing carbon-silicon sorbents that demonstrate high efficiency in capturing various types dust particles, along with partial antibacterial activity. Dust particles ranging from 0.65 to 150 microns were effectively retained by sorbent, organic capture varying between 74% and 98%, making these suitable for air purification highly polluted indoor environments. activity was tested on Bacillus paramycoides Pseudomonas koreensis strains using diffusion method a solid nutrient medium. Testing showed sorbent samples different concentrations active ingredient exhibited degrees bacterial growth suppression, Sample No. 2 demonstrating highest Optimizing composition increasing concentration components may enhance its properties. These hold great potential use systems additional protection against contamination, them promising environments standards hygiene cleanliness.
