Abstract
A method of generating a non-thermal microplasma, including the steps of providing a fibrous air-filter, arranging one or more pairs of elongated, adjacent, substantially parallel spaced-apart electrodes on the fibrous air-filter, wherein a discharge gap is defined between each pair; placing a component in signal communication with the electrodes for applying a voltage between each pair; and generating a non-thermal microplasma in a corresponding discharge gap and thereby removing one or more combustion byproducts from ambient air.
