Suction cup filtration fitting
An apparatus includes a suction cup, a fitting, and a filter. The suction cup defines an interior cavity with a first opening and a second opening. The fitting is coupled to the suction cup. The fitting includes a first portion and a second portion. The first portion of the fitting defines a chamber. The second portion of the fitting is positioned within the interior cavity and is coupled to the first portion of the fitting to secure the first portion of the fitting to the suction cup. The filter is positioned within the chamber such that the suction cup and the fitting define a passage from the second opening, through the interior cavity, and through the chamber and the filter.

2. The apparatus of claim 1 , wherein the retaining member defines a plurality of apertures that open towards the bottom opening when a bottom portion of the fitting is engaged with the top portion of the fitting in the interior cavity.
3. The apparatus of claim 2 , wherein the bottom portion of the fitting couples to the top portion of the fitting by twisting onto the top portion of the fitting.
4. An apparatus comprising:
a suction cup that defines an interior cavity with a first opening and a second opening;
a fitting coupled to the suction cup, the fitting comprising a first portion and a second portion, wherein:
the first portion defines a chamber; and
the second portion of the fitting is positioned within the interior cavity and is coupled to the first portion of the fitting to secure the first portion of the fitting to the suction cup, wherein the second portion of the fitting is rounded such that the second portion of the fitting defines a cavity between the first portion of the fitting and the chamber; and
a filter positioned within the chamber such that the suction cup and the fitting define a passage from the second opening, through the interior cavity, and through the chamber and the filter.
5. The apparatus of claim 4 , wherein:
the first portion of the fitting is sized to engage the suction cup through the first opening; and
the second portion of the fitting is sized to fit through the second opening and to engage the first portion of the fitting within the interior cavity.
6. The apparatus of claim 4 , wherein the second portion of the fitting defines a plurality of apertures that open towards the second opening.
7. The apparatus of claim 4 , wherein the second portion of the fitting couples to the first portion of the fitting by twisting onto the first portion of the fitting.
8. The apparatus of claim 4 , wherein the first portion of the fitting is configured to engage a vacuum.
9. The apparatus of claim 4 , wherein the first portion of the fitting comprises a rim that has a width greater than a width of the first opening.
10. The apparatus of claim 9 , wherein the second portion of the fitting has a width greater than the width of the first opening.
11. The apparatus of claim 4 , wherein the first portion of the fitting extends beyond the first opening.
12. The apparatus of claim 4 , wherein:
the filter is cylindrical and comprises a top surface coupled to a side surface; and
the filter further comprises a flange coupled to the side surface.
13. An apparatus comprising:
a suction cup that defines an interior cavity with a first opening and a second opening;
a fitting coupled to the suction cup, wherein the fitting extends through the first opening and into the interior cavity and wherein the fitting defines a chamber, wherein the fitting comprises a first portion that extends through the first opening and into the interior cavity, and a second portion that is positioned within the interior cavity and is coupled to the first portion of the fitting to secure the first portion of the fitting to the suction cup; and
a filter positioned within the chamber such that the suction cup and the fitting define a passage from the second opening, through the interior cavity, and through the chamber and the filter, wherein the filter is cylindrical and comprises a top surface coupled to a side surface, and wherein the filter further comprises a flange coupled to the side surface.
14. The apparatus of claim 13 , wherein:
the first portion of the fitting is sized to engage the suction cup through the first opening; and
the second portion of the fitting is sized to fit through the second opening and to engage the first portion of the fitting within the interior cavity.
15. The apparatus of claim 13 , wherein the second portion of the fitting defines a plurality of apertures that open towards the second opening.
16. The apparatus of claim 13 , wherein the second portion of the fitting couples to the first portion of the fitting by twisting onto the first portion of the fitting.
17. The apparatus of claim 13 , wherein the first portion of the fitting comprises a rim with a width greater than a width of the first opening.
