The following experiment was set up to illustrate the impact of the UVC light in the EnviroKlenz Air System. Two EnviroKlenz Air Systems were set up in the same indoor air environment with HEPA filters installed. HEPA filters are designed to capture a broad range of particulate matter 0.3 microns in size and larger.
In one system the UVC light bulbs were turned on, while in the other system UVC lights were not used. The systems were allowed to collect particulate matter for 1 week. After the week of collection ended, the systems were turned off and the HEPA surface was sampled with sterile collection swabs and streaked onto the nutrient agar plates (MEA). The plates were then allowed to incubate for 10 days.
In this image, the plates are observed. The MEA plate on the left has mold growth. This was the sample collected from the system without the UVC lights running, while the sample on the right shows the UVC light being on killed the mold and the resulting plate with no growth observed.
