Explanation of success
At the time of testing, the existing filtration system in the HVAC system demonstrated a successful reduction of particles sized 1 – 10 microns. However, the existing filtration technology was not addressing sub-micron sized particles. Submicron sized particles range from the >1 micron of smoke to that of 0.01 microns of a virus.
Testing on the same HVAC equipment, with the additional use of Phenomenal Aire™, indicated the successful filtration of submicron sized particles ranging in size from 0.3 to 0.5 microns. Physical limitations of the indoor air monitoring technology did not allow for the measurement of particles as small as 0.01 microns.
The introduction of ionization, or charged molecules, results in like particles bonding to other like particles. As particles bond to other particles they become a particle of greater size and mass. The bonding of particles to other particles is referred to as agglomeration. A particle .03 microns in size may increases to .05 microns. A particle .05 microns may increase in size to 1 micron, etc. As the particulates increase in size the effectiveness of the air filtration technology also increases. Which, accounts for the results demonstrated in the casino HVAC filtration technology.
While the meter technology used during the two day casino test was limited to measurements greater than 0.01 microns, the physical principals of agglomeration are not limited to the initial size of particles. Therefore, it can be assumed that particles with initial measurements as small as .01 microns also grew in size and ultimately became subject to capture over time.
