Abstract
Described is an air and surface purifying device having a purifying cell structured for maximizing the realized photocatalytic reaction at a photocatalytic surface without using an additional ultraviolet bulb. The purifying cell positions at least three photocatalytic surfaces about a single ultraviolet bulb such that the photocatalytic surfaces substantially encompass the ultraviolet bulb and are saturated by ultraviolet light radiating from the ultraviolet bulb. Because the photocatalytic surfaces are saturated, the potential photocatalytic reaction at the photocatalytic surfaces is fully realized. Stated differently, the realized photocatalytic reaction is maximized. Because the purifying cell maximizes the realized photocatalytic reaction, the purifying cell maximizes the purifying capacity of the photocatalytic surface and, thus, the purifying cell itself.
