Abstract

A method and apparatus for wet filtering machine exhaust is disclosed.

Claims

1. An apparatus for wet filtering machine exhaust comprising:

a. a plurality of filter sticks secured in a filter, wherein said filter sticks are constructed to filter machine exhaust;

b. a fluid mixture delivery container for delivering a fluid mixture to the filter sticks;

c. a positioning attachment for attaching the filter to a machine with the plurality of filter sticks in the line of flow of the machine exhaust; and

d. an adsorbent pad atop the filter sticks for controlling the flow of fluid mixture to the filter sticks.

2. The apparatus of claim 1 wherein the fluid mixture delivery container includes a removable lid.

3. The apparatus of claim 1 wherein the filter includes a removable lid beneath the filter sticks for accessing the filter sticks.

7. The apparatus of claim 3 wherein the fluid mixture delivery container includes natural ethereal oil, water, and an emulsifier.

8. The apparatus of claim 7 wherein the oil mixture is scented.

4. An apparatus for wet filtering machine exhaust comprising:

a. a plurality of filter sticks secured in a filter, wherein said filter sticks are constructed to filter machine exhaust;

b. a fluid mixture delivery container for delivering a fluid mixture to the filter sticks, wherein the fluid mixture delivery container includes an ethereal oil mixture; and

c. a positioning attachment for attaching the filter to a machine with the plurality of filter sticks in the line of flow of the machine exhaust.

5. The apparatus of claim 4 wherein the ethereal oil mixture includes natural ethereal oil, water, and an emulsifier.

6. The apparatus of claim 5 wherein the ethereal oil mixture is scented.

9. An apparatus for wet filtering machine exhaust comprising:

a. a plurality of filter sticks secured in a filter, wherein said filter sticks are constructed to filter machine exhaust;

b. a fluid mixture delivery container for delivering a fluid mixture to the filter sticks; and

c. a positioning attachment for attaching the filter to a machine with the plurality of filter sticks in the line of flow of the machine exhaust, wherein the attachment is a hook and loop attachment.

10. A method for wet filtering machine exhaust comprising positioning a plurality of filter sticks in the line of flow of machine exhaust, delivering fluid mixture to the filter sticks, wherein the fluid mixture includes ethereal oil, and disposing of pollutants from the machine exhaust collected on the filter sticks.

11. The method of claim 10 wherein the fluid mixture includes natural ethereal oil, water, and an emulsifier.

12. The method of claim 11 wherein the fluid mixture is scented.

15. The method of claim 10 wherein said disposing of pollutants includes discarding one or more filter sticks.

16. The method of claim 15 wherein the fluid mixture is scented.

13. A method for wet filtering machine exhaust comprising positioning a plurality of filter sticks in the line of flow of machine exhaust, delivering a fluid mixture to the filter sticks, wherein the fluid mixture includes natural ethereal oil, water, and an emulsifier, and disposing of pollutants from the machine exhaust collected on the filter sticks, wherein said disposing of pollutants includes washing the filter sticks.

14. The method claim 13 wherein the fluid mixture is scented.

17. An apparatus for providing a desired smell into the environment comprising:

a. one or more fluid conduction sticks;

b. a scented fluid mixture conducted along said one or more sticks; and

c. a fluid delivery container for delivering the scented fluid mixture to the sticks.

18. The apparatus of claim 17 wherein the fluid delivery container is refillable.

19. The apparatus of claim 18 wherein the scented fluid mixture comprises ethereal oil.

20. The apparatus of claim 19 wherein the scented fluid mixture comprises natural ethereal oil water and emulsifier.

21. The apparatus of claim 17 wherein the scented fluid mixture comprises ethereal oil.

22. The apparatus of claim 20 wherein the scented fluid mixture comprises natural ethereal oil, water and emulsifier.

23. The apparatus of claim 22 further comprising a fan attached behind said one or more sticks for blowing said smell into the ambient air.

24. The apparatus of claim 17 further comprising a fan attached behind said one or more sticks for blowing said smell into the ambient air.

25. The apparatus of claim 18 further comprising a fan attached behind said one or more sticks for blowing said smell into the ambient air.

26. The apparatus of claim 19 further comprising a fan attached. behind said one or more sticks for blowing said smell into the ambient air.
