Abstract: Disclosed is a portable air filtration system for removing contaminants from room air. In one embodiment, the air filtration system includes a power supply and an air blower module electrically connected to the power supply. The air filtration system further includes an ionization module engaged with the air blower module and including a first control grid and a high voltage grid electrically connected to the power supply. The air filtration system further includes a filter module removably engaged with the ionization module. The filter module includes 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 and 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.
