Abstract

A filter assembly including a plurality of filter modules, wherein each filter module in the plurality of filter modules includes a frame, a filtration element coupled within the frame, and at least one mating feature. The at least one mating feature of each filter module is configured for selective engagement with the at least one mating feature of another filter module such that the plurality of filter modules are coupled together in a serial arrangement.

First claim

What is claimed is:

1. A filter assembly comprising:
a plurality of filter modules, wherein each filter module in said plurality of filter modules comprises:
a frame;
a filtration element coupled within said frame; and
at least one mating feature, wherein said at least one mating feature of said each filter module is configured for selective engagement with said at least one mating feature of another filter module such that said plurality of filter modules are coupled together in a serial arrangement, wherein said at least one mating feature of said each filter module is configured to prohibit serially coupling the plurality of filter modules together in predetermined combinations based on a type of filtration element coupled within said each filter module, and wherein the plurality of filter modules are selectively interchangeable with each other in different sequences to define the predetermined combinations.

2. The filter assembly in accordance with claim 1 , wherein said filtration element of at least one of said filter modules comprises one of a particulate filter media and an absorptive filter media.

3. The filter assembly in accordance with claim 1 , wherein said filtration element of at least one of said filter modules comprises one of a regenerative heating element, an ultraviolet irradiation element, and an ozone converter element.

4. The filter assembly in accordance with claim 1 , wherein at least one filter module in said plurality of filter modules comprises a first mating feature and a second mating feature, said first mating feature configured for female connectivity, and said second mating feature configured for male connectivity.

5. The filter assembly in accordance with claim 4 , wherein said frame of said at least one filter module comprises a receiving arm that extends beyond said filtration element of said at least one filter module, wherein one of said first mating feature and said second mating feature is positioned along said receiving arm.

6. An air purification system comprising:
an inlet;
an outlet; and
a filter assembly comprising a plurality of filter modules positioned between said inlet and said outlet, wherein each filter module in said plurality of filter modules comprises:
a frame;
a filtration element coupled within said frame; and
at least one mating feature, wherein said at least one mating feature of said each filter module is configured for selective engagement with said at least one mating feature of another filter module such that said plurality of filter modules are coupled together in a serial arrangement, wherein said at least one mating feature of said each filter module is configured to prohibit serially coupling the plurality of filter modules together in predetermined combinations based on a type of filtration element coupled within said each filter module, and wherein the plurality of filter modules are selectively interchangeable with each other in different sequences to define the predetermined combinations.

7. The system in accordance with claim 6 , wherein said plurality of filter modules comprises a first filter module comprising a particulate filter media, said at least one mating feature of said first filter module configured based on the predetermined combinations such that said particulate filter media is positioned nearest said inlet relative to a remainder of said plurality of filter modules.

8. The system in accordance with claim 6 , wherein said plurality of filter modules comprises a first filter module comprising a particulate filter media, and a second filter module comprising an absorptive filter media, said at least one mating feature of said first filter module and said second filter module configured based on the predetermined combinations such that said particulate filter media is positioned upstream from said absorptive filter media.

9. The system in accordance with claim 8 , wherein said plurality of filter modules comprises a third filter module comprising a regenerative heating element, said at least one mating feature of said second filter module and said third filter module configured based on the predetermined combinations such that said regenerative heating element is positioned upstream from said absorptive filter media.

10. The system in accordance with claim 6 further comprising an intake plenum structure that defines said outlet, said intake plenum structure comprising a connector configured for universal engagement with said at least one mating feature of said each filter module.

11. The system in accordance with claim 6 , wherein said filtration element of at least one of said filter modules comprises one of a particulate filter media and an absorptive filter media.

12. The system in accordance with claim 6 , wherein said filtration element of at least one of said filter modules comprises one of a regenerative heating element, an ultraviolet irradiation element, and an ozone converter element.

13. An aircraft comprising the air purification system of claim 6 .

14. A method of assembling an air purification system having an inlet and an outlet, said method comprising:
positioning a filter assembly between the inlet and the outlet, wherein the filter assembly includes a plurality of filter modules;
selectively engaging the plurality of filter modules with each other such that the plurality of filter modules are coupled together in a serial arrangement, wherein each filter module includes at least one mating feature for coupling the plurality of filter modules together, the at least one mating feature of said each filter module selected such that the serial arrangement is predetermined, wherein said at least one mating feature of said each filter module is configured to prohibit serially coupling the plurality of filter modules together in predetermined combinations based on a type of filtration element coupled within said each filter module; and
arranging the plurality of filter modules in predetermined combinations based on the type of filtration element housed within each filter module, wherein the plurality of filter modules are selectively interchangeable with each other in different sequences to define the predetermined combinations.

15. The method in accordance with claim 14 , wherein the plurality of filter modules includes a first filter module including a particulate filter media, wherein arranging the plurality of filter modules comprises arranging the first filter module based on the predetermined combinations such that the particulate filter media is positioned nearest the inlet relative to a remainder of the plurality of filter modules.

16. The method in accordance with claim 14 , wherein the plurality of filter modules includes a first filter module including a particulate filter media, and a second filter module including an absorptive filter media, wherein arranging the plurality of filter modules comprises arranging first filter module and the second filter module based on the predetermined combinations such that the particulate filter media is positioned upstream from the absorptive filter media.

17. The method in accordance with claim 16 , wherein the plurality of filter modules includes a third filter module including a regenerative heating element, wherein arranging the plurality of filter modules comprises arranging the second filter module and the third filter module based on the predetermined combinations such that the regenerative heating element is positioned upstream from the absorptive filter media.

18. The filter assembly in accordance with clai
