Abstract

Disclosed is a portable air filtration system for removing contaminants from room air. In one embodiment, the air filtration system comprises a power supply and an air blower module electrically connected to the power supply. The air filtration system further comprises an ionization module engaged with the air blower module and comprising a first control grid and a high voltage grid electrically connected to the power supply. The air filtration system further comprises a filter module removably engaged with the ionization module. The filter module comprises a filter and a second control grid. Engagement of the filter module and the ionization module creates an electrical connection between the second control grid an the power supply. Activation of the air filtration system creates a first ionization field between the high voltage grid and the first control grid and a second ionization field between the high voltage grid and the second control grid.
