Abstract

A self contained air purification pyramid shaped system and apparatus that can form up to approximately 300 cfm of air flow at high speed, that can remove allergy causing particulates, microorganisms, and odors/chemicals from the air so as to create a healthier environment. The system and apparatus can use a carbon prefilter for removal of larger particulate and odors/chemicals and gases, a UV(ultra violet) lamp for destruction of bacteria, viruses, and molds, and a hospital grade HEPA filter (approximately 99.97% efficient at approximately 0.3 microns) for removal of smaller particulate and bacteria. Air can first enter the peak of the pyramid shaped apparatus, pass through a carbon prefilter, past the UV lamp(s), through filter, such as a HEPA filter, and through a motorized impeller which pushes the air out lower sides of the apparatus. In addition to attacking airborne bacteria and viruses, the UV lamp can continually bathe the “dirty” side of the HEPA filter (the side of the filter on which the microorganisms are collected), thereby deactivating any microorganisms that have been collected and preventing bacteria/mold growth on the HEPA. The invention can be used in commercial, personal and any environment for improving indoor air quality. Embodiments can include floor supported stand, a table top version and a mount for securing to a wall.

Claims

1. A self contained air purification apparatus, comprising:

sloped angled exterior walls on the apparatus;

an air inlet port adjacent to a top portion of the apparatus for receiving incoming air;

means for filtering the incoming air inside the apparatus;

means for pulling the air through the apparatus; and

an exhaust port adjacent to a lower portion of the apparatus spaced below the inlet port for allowing cleaned air to be substantially circulated about the apparatus.

2. The apparatus of claim 1, wherein the angled walls include:

an upright pyramid with the air inlet port on at least one upper face portion of the pyramid shape, and the exhaust port on at least one lower face of the pyramid shape.

3. The apparatus of claim 2, wherein the air inlet port is located on two faces of the pyramid.

4. The apparatus of claim 2, wherein the pyramid includes:

an upper pyramid portion separate from a lower pyramid portion, the upper pyramid portion having at least one face with a different slanted angle than at least one other face.

5. The apparatus of claim 2, wherein the exhaust port is located on three faces.

6. The apparatus of claim 2, wherein the pyramid includes:

three exterior faces.

7. The apparatus of claim 2, wherein the pyramid includes:

four exterior faces.

8. The apparatus of claim 2, wherein the pyramid includes:

five exterior faces.

9. The apparatus of claim 1, further comprising:

means for circulating up to approximately 300 cfm of cleaned air.

10. The apparatus of claim 1, further comprising:

light means for simultaneously cleaning both the incoming air and the filtering means.

11. The apparatus of claim 10, wherein the light means includes:

a UV(ultra violet) source.

12. The apparatus of claim 11, further comprising:

means for positioning the UV source adjacent and above a surface of the filtering means where microorganisms and mold become collected.

13. The apparatus of claim 1, wherein the filtering means includes:

a HEPA filter tested to achieve up to approximately 99.97% efficiency at approximately 0.3 microns.

14. The apparatus of claim 1, further comprising:

at least one removable filter for the filtering means; and

means for sealing edges of the at least one filter, within the apparatus so that incoming air does not bypass the at least one filter.

15. The apparatus of claim 14, wherein the sealing means includes:

a gasket an rail for allowing the at least one filter to slide in and out of the apparatus.

16. The apparatus of claim 1, further comprising:

a removable back panel on the apparatus so that components within the apparatus can be serviced without using extra tools to open and access the components in the apparatus.

17. The apparatus of claim 16, wherein the components include:

a UV lamp;

a removable filter; and

a blower.

18. The apparatus of claim 15, further comprising:

means for automatically turning off power to the apparatus when the back panel is opened.

19. The apparatus of claim 1, wherein the filtering means includes:

a carbon filter positioned within the apparatus for removing odors and chemicals; and

a HEPA filter positioned below the carbon filter.

20. The apparatus of claim 19, further comprising:

a UV lamp positioned between the carbon filter and the HEPA filter.

21. The apparatus of claim 1, further comprising:

a removable floor based stand for positioning the apparatus above various floor locales.

22. The apparatus of claim 1, further comprising:

means for positioning the apparatus on a table.

23. The apparatus of claim 1, further comprising:

means for mounting the apparatus to various wall height positions.

24. A method of cleaning and circulating air from a self-contained system, comprising the steps of:

providing an air cleaning device having outwardly sloping exterior walls;

pulling incoming air into at least one upper face portion on at least one of the walls;
