What is claimed as new and desired to be secured by Letters Patent of the United States is: 1. A fluid filtration system, comprising: a housing having first, second and third openings formed therein; a cap removably and sealably attached to said first opening; a first tube sealably coupled to said second opening, said first tube extending to a free end thereof; a second tube sealably coupled to said third opening, said second tube extending to a free end thereof; a one-way check valve fitted in said first tube, said check valve prohibiting movement of fluent material therethrough towards said second opening; and a filter assembly fitted in said housing and, in combination with said housing, defines a first chamber accessible via said third opening and a second chamber accessible via said second opening and sealed by said cap wherein, when a fluid to be filtered is present at said free end of said second tube and suction is applied to said second opening via said free end of said first tube, fluid is (i) drawn into said first chamber, (ii) through said filter assembly, (iii) into said second chamber, and (iv) to said second opening. 2. A fluid filtration system as in claim 1 wherein said second opening and said third opening are on different sides of said housing. 3. A fluid filtration as in claim 1 wherein said second opening is accessible to said second chamber via a passageway formed through said filter assembly. 4. A fluid filtration system as in claim 1 further comprising a filter fitted in said second tube. 5. A fluid filtration system as in claim 1 wherein said housing defines an annular recess around each of said second opening and said third opening. 6. A fluid filtration system as in claim 1 wherein said housing at said first opening is adapted to be coupled to a container. 7. A fluid filtration system as in claim 1 wherein said cap comprises a container. 8. A fluid filtration system, comprising: a cylindrical housing having first and second axial ends and a cylindrical side wall, said cylindrical housing having (i) a first opening formed through said first axial end, (ii) a second opening formed through said second axial end, and (iii) a third opening formed through one of said second axial end and said cylindrical side wall; a cap removably and sealably attached to said first opening; a first tube sealably coupled to said second opening, said first tube extending to a free end thereof; a second tube sealably coupled to said third opening, said second tube extending to said free end thereof; a one-way check valve fitted in said first tube, said check valve prohibiting movement of fluent material therethrough towards said second opening; and a filter assembly fitted within said cylindrical housing and, in combination with said cylindrical housing, defines a first chamber accessible via said third opening and a second chamber accessible via said second opening and sealed by said cap wherein, when a fluid to be filtered is present at said free end of said second tube and suction is applied to said second opening via said free end of said first tube, the fluid is (i) drawn into said first chamber, (ii) through said filter assembly, (iii) into said second chamber, and (iv) to said second opening. 9. A fluid filtration system as in claim 8 wherein said second opening is accessible to said second chamber via a passageway formed through said filter assembly. 10. A fluid filtration system as in claim 8 wherein said cap has a recessed portion that lies within the confines of said cylindrical housing, said system further comprising attachment means coupled to said cap in said recessed portion thereof, and adapted to be attached to a disparate device. 11. A fluid filtration system as in claim 8 further comprising a filter fitted in said second tube. 12. A fluid filtration system as in claim 8 wherein said housing defines an annular recess around each of said second opening and said third opening. 13. A fluid filtration system as in claim 8 wherein said housing at said first opening is adapted to be coupled to a container. 14. A fluid filtration system as in claim 8 wherein said cap comprises a container. 15. A fluid filtration system, comprising: a cylindrical housing having first and second axial ends, said first axial end defining a first opening that spans an internal diameter of said cylindrical housing, and said second axial end having second and third openings formed therein with an annular recess being formed in said second axial end around each of said second opening and said third opening; a cap in threaded engagement with said cylindrical housing to seal said first opening; a first tube having one end thereof inserted into said annular recess formed around said second opening for forming a sealing engagement therewith, said first tube having a second end that is free; a second tube having one end thereof inserted into said annular recess formed around said third opening for forming a sealing engagement therewith, said second tube having a second end that is free; a one-way check valve fitted in said first tube, said check valve prohibiting movement of fluent material therethrough towards said second opening; and a filter assembly fitted within said cylindrical housing and, in combination with said cylindrical housing, defines a first chamber accessible via said third opening and a second chamber accessible via said second opening and sealed by said cap, said filter assembly having an unobstructed passageway formed therethrough that coupled said second opening to said second chamber wherein, when a fluid to be filtered is present said second end of said second tube and suction is applied to said second opening via said second end of said first tube, the fluid is (i) drawn into said first chamber, (ii) through said filter assembly, (iii) into said second chamber, and (iv) to said second opening via said unobstructed passageway. 16. A fluid filtration system as in claim 15 wherein said cap has a recessed portion that lies within the confines of said cylindrical housing, said system further comprising attachment means coupled to said cap in said recessed portion thereof, and adapted to be attached to a disparate device. 17. A fluid filtration system as in claim 15 further comprising a filter fitted in said second tube. 18. A fluid filtration system as in claim 15 wherein said housing at said first opening is adapted to be coupled to a container. 19. A fluid filtration system as in claim 15 wherein said cap comprises a container.
