Chinese Ministry of Health - April 2006
Within a 20 m3 test chamber triplicate tests determined the survival/natural decay rate of aerosolised bacteria (White Staph (8032)) suspended in the air; samples being taken at 0, 60 and 120 minutes. The triplicate tests were then repeated with a SafeAirTM 3500 unit on Turbo setting operating in the chamber and air samples were taken at the same time intervals.
It is important to note that the figures shown on this graph do not illustrate the actual levels of pathogens remaining at any time during the Test. Rather, they show the level of accelerated destruction of the pathogens over and above the rate of natural decay that would occur under test conditions. A horizontal line taken from 100% on the Y Axis represents the normal levels of decay over the duration of the Test (time/X-Axis) and the charted lines show the levels of pathogens that survived with the SafeAirTM equipment running.
Specifically, the results of these tests show that after 60 minutes an average of 95.9%, and after 120 minutes an average of 98.6% of the aerosolised bacteria in the test chamber were destroyed* over and above the natural decay rate.
* The term 'destroy' means to either kill airborne bacteria, or to remove the ability of airborne bacteria to reproduce.
