Embodiment Construction

[0028] figure 1 A perspective view showing the appearance of the portable germicidal air filter denoted by reference numeral 10 . The germicidal air filter 10 includes a compartment 12 having a front wall 14 and two opposing side walls 16 . The front wall 14 includes an air intake area 18 which may be louvered (as shown) or covered with coarse grained open foam (not shown) or the like. This air intake zone allows air to be filtered to be drawn into the chamber. Each side wall 16 includes a respective exhaust area 20, which is preferably covered with a grille, but may also be covered with louvers or the like. The top of the front wall 14 also includes a control panel 22 which will be explained in more detail with reference to FIG. 7 .

[0029] Figure 2 shows the germicidal air filter 10 with the service door 24 in an open position. A service door 24 forms a substantial portion of the front wall 14 and is hinged to the side wall 16 so that it can be easily opened for servici...

Abstract

A lightweight portable germicidal air filter for home and personal use is disclosed. The air filter includes a cabinet which houses an electrostatic air filter, an ultraviolet lamp and a parabolic reflector or a convex lens for focusing the ultraviolet radiation emitted by the lamp on an upstream side of the air filter. The reflector or the lens are constantly oscillated to systematically sweep the upstream side of the filter with germicidal levels of radiation. A fan located adjacent the downstream side of the filter draws air through the filter and impels it out through areas for air outlet in the sidewalls of the cabinet. The advantage is a simple, lightweight germicidal air filter with few moving parts which is inexpensive to manufacture.

Description

technical field [0001] The present invention relates to the removal of suspended particulate matter from air, and in particular, to the removal of particulate matter from air by filtration and the destruction of microorganisms in the removed particulate matter. Background technique [0002] Airborne transmission of pathogenic organisms, especially respiratory pathogens, has long been recognized as a serious problem. Now, health care organizations and aerobiologists have become acutely aware of the problems posed by the development of antibiotic-resistant strains of bacteria such as Streptococcus and Tuberculosis. Although the mechanisms of airborne disease are not fully understood, it is clear that many diseases caused by both bacteria and viruses are transmitted primarily from host to host by air currents. It is also understood that certain infectious agents, such as tuberculosis bacteria, can survive for many hours suspended in the air. Therefore, unless the air is treat...
