The objective of this project was to assess microbial concentrations in air and on fomites in Ingham Hospitals before and after the installation of a UVGI-HVAC system. Using bacteria and fungi concentrations as a standard of effectiveness of the UVGI-HVAC system, indoor air samples
were collected at Greenlawn Campus and Ingham Orthopaedic before and after installation and microbial levels were compared.
“Average levels (organisms/m3 air) of total bacteria found in the air prior to the UV installation were 45.5 and 25.5“
“Average levels (organisms/m3 air) of total bacteria found in the airafterthe UV installation were 8.67 and .418“
