Chicago Public School 135 began the installation of 58 Guardian Air units to assist in reducing absenteeism due to illness. Members of the school district met with RGF and G.W. Berkheimer to discuss ongoing problems with the air quality in the school.
Like many older schools there were many complaints regarding the air quality. The most common were mold, musty odors and teachers complaining of being uncomfortable in certain rooms. The RGF factory personnel explained the unique approach to air quality that the Guardian Air family of products provides; its ability to kill microbes (mold, bacteria, and viruses) in the conditioned space instead of trying to kill them in the air handler. They also informed the members of the school district that a well-known cruise line had installed them in all of their cruise ships to protect passengers from the Norwalk Virus. During the discussion, RGF shared with the school district the results of a test done by Midwest Research Institute (MRI), where the Guardian Air achieved a kill rate on Norwalk Virus of 99.9999% in a series of one hour tests. It is important to note that the Norwalk Virus is the cause of 54% of all stomach flu American suffers each year.
The school district decided to try the product and would phase it in during class room modifications. As part of the project, the school decided to run preliminary studies on the effect on absenteeism verses the same period a year earlier. The results showed that with the Guardian Air units installed, the absenteeism fell by 15-20%. This is very important point for all school districts as they receive their federal and state funding based on daily attendance records. So the more students in school, the more funding they receive. In essence, PS 135 got an increase in their funding of 15-20%.
