※The same results were confirmed with Salmonella, candida, and black aspergillus.
A piece of brown filter paper was put in a Petri dish with agar culture media applying Coli bacillus. In a dish as control, certain amount of water was put on the filter paper. The same amount of π-clean was put on a filter in another dish as test. Two dishes were placed in 36 decrees C of temperature and 60% of humidity. A picture was taken after 24hours.
