Ultra Violet Air Purifier Light Installed
in Air Duct

Environmental Compliance Solutions, an independent environmental and safety consulting company located in Troy, MI tested the AirPal Spectra's air purification lights (non-ozone) in residential air ducts. After a six week period of air purification, total fungi (mold) in the air was reduced from over 600CFU/Cubic Meter to less than 50CFU/Cubic Meter — a reduction of more than 90%.

After six weeks, levels did go up slightly, but then remained constant for the 20-week test period at approximately 100CFU/Cubic Meter. According to environmental standards, the recommended level for healthy indoor environments is 200 CFU/Cubic Meter or less.

The study was conducted in an actual residential environment using the AirPal Spectra air purifier. Samples were collected in petri dishes on a regular basis in the kitchen and bedroom to measure the fungi levels.

CFU's are colony forming units.
