Embodiments of the present disclosure could generally provide an active oxidation and purifying system to maximize the rate of photocatalytic oxidation and ambient air filtration by structurally optimizing the system to maximize potential ultraviolet (UV) light exposure to the surface and apertures of the active power cells. In one example, the active power cells could include a plurality of apertures disposed in a transverse manner from the first surface to the second surface of the active power cell. For example, the first set of the apertures could be disposed about 45 degrees relative to a median axis along the first and second surfaces, while a second set of apertures could be disposed about negative 45 degrees relative to the same median axis.
