Abstract
Abstract An air purifying apparatus presenting the appearance of a side table is constructed from a side table housing having a hollow interior compartment, an inlet port and an exhaust port. A filtration means is positioned within the hollow interior compartment between the inlet port and the exhaust port so that air entering the inlet port must pass through the filtration means before exiting through the exhaust port. An air blower means is also positioned within the hollow interior compartment between the inlet port and the exhaust port so as to draw air into the inlet port and out through the exhaust port.
