    The objective of this thesis was to compare the implementation of the membrane filtration method using the EZ-FITTM filtration system in a pharmaceutical candy laboratory for the analysis of purified water. The research design was observational, analytical, and descriptive. The study confirmed that the percentage of recovery for the inoculated microorganisms was greater than 70%. It was also evident that the data had a normal distribution, which allowed for the use of the Student's t-test to compare the results of both methods, with a 95% confidence level for the intervals of microbial counts. The comparison was made between the TSA agar medium method and the EZ-FITTM membrane filtration method. This work determined that the mean differences in CFU recovery for E. coli, P. aeruginosa, and S. aureus cultures were not statistically significant, meaning that either technique would provide satisfactory results. Ultimately, according to its established procedures, the laboratory decides which method to apply, prioritizing the benefits of its management.
