Indoor time has increased due to global temperature instability, prompting establishments like schools, hospitals, and offices to install air-conditioning units. These units can circulate airborne bacterial pathogens despite their prevalence, potentially posing health risk. Air purifiers are increasingly considered as a supplemental measure to mitigate this issue, yet their effectiveness hinges on proper usage. This study aimed to identify bacteria in air-conditions rooms with and without air purifiers, assessing changes in bacterial contamination over 1 1/2 and 3 hours. The experimental design involved sampling air in the Medical Technology Laboratory (with an air purified) and the Nursing Skills Laboratory Nutrient agar Plates exposed for specified intervals were incubated and analyzed for Gram- negative and Gram- positive bacteria. Results showed that in rooms with air purifiers, bacteria included Staphylococcus aureus, Bacillus species, Pseudomonas aeruginosa, and Shigella spp., with 73 colonies at 1 1/2 hours and 113 at 3 hours.
