Abstract
This article describes tests of nonwoven antimicrobial filter materials from viscose fibre (rayon) containing the antimicrobial preparations catamin AB and desant. Wide-ranging tests of antimicrobial filter materials have been carried out to determine the aerodynamic characteristics, dust content and dust penetrability, weather tolerance, resistance to saprophytic (mold) fungi, etc. The tests and function-based classification of antimicrobial filter materials comply with GOST R 51251. Investigations were carried out at the microbiological laboratories of I. V. Michurin All-Russia Scientific Research Institute of Orcharding, Center of Hygiene and Epidemiology in the Moscow Region, and FGU “Mendeleevskii TsSM” to determine the efficiency of air purification from microorganisms by antimicrobial filter materials made of viscose fibre containing the preparations catamin AB and desant employing a specially designed equipment. Performance tests of various types of air filters having filter elements from filter materials containing desant and catamin AB have been carried out. The efficiency of air purification from the microorganisms Staphylococcus aureus, Micrococcus falvus, Bacillus subtilis, etc. that infect patients in medical institutions has been determined.
