Indoor air quality was analyzed in the period from 2016 to 2019, in the Universidad Iberoamericana Torreón, with the objective of determining if it complied with the reference norms: ISO 14644- 1-2015 and UNE 100012:2005; due to in Mexico there are no applicable norms for the monitoring or indication of the Maximum Permissible Limits to determine indoor air quality. Methodology applied was focused on: 1) Determining the PSTs (from 0.3 to 10 µm) using a FLUKE particle counter; 2) Microbiological analysis; 3) Identifying isolated strains and 4) Calculating origin and wind intensity using a METPAK II climatological data and a WRPLOT software. PST and microbiological concentrations were found to be above the standards used. PS0.3 showed a significant difference (p<0.05) in the Auditorium, which had the highest concentrations in 2019 of evening schedule. Some of the biological material were identified as: 1) pathogenic bacteria of the genera Salmonella, Klebisella and Escherichia, and 2) fungi of the genera Aspergillus, Trichophyton and Candida; whose exposure could produce different allergies, asthma, develop respiratory symptoms, chronic cough, laryngitis, sinusitis and urticaria.
