1. A filter holder, comprising:

a. a front piece, comprising, i) a front wall having a base, a first side edge and a second side edge, ii) a first front side wall and iii) a second front side wall, said first front side wall connected with the first side edge of the front wall and said second front side wall connected to the second edge of the front wall, both the first front side wall and second front side wall at substantially a right angle to said front wall, wherein said base extends from and is connected to said first front side wall forming a first junction, said second front side wall, forming a second junction, and said front wall and, further, extends beyond said front wall in a direction opposite of said first front side wall and said second front side wall, it's plane substantially perpendicular to the planes of the first side wall, the second side wall and the front wall;

b. a rear piece, comprising, i) a back wall having a base, ii) a first rear side wall and iii) a second rear side wall, the first rear side wall and the second rear side wall being essentially cylindrical and hollow and extending from said back wall at essentially right angles forming a first cylindrical rear side wall and a second cylindrical rear side wall, wherein said base extends from and is connected to said first rear side wall, said second rear side wall and said back wall and, further, extends beyond said back wall in a direction opposite of said first rear side wall and said second rear side wall;

c. the front piece further comprising, at the first junction, a first cylindrical opening; and at the second junction, a second cylindrical opening; said first and said second cylindrical openings being aligned with the first cylindrical rear side wall and the second cylindrical opening being aligned with said second cylindrical rear side wall when the front piece is aligned with the rear piece;

d. a first magnet, sized to fit into said first cylindrical rear side wall and said first front cylindrical opening, and a second magnet size to fit into the second rear side wall and said second cylindrical opening when the front piece is aligned with and connected to the rear piece.

2. The filter holder of claim 1 , wherein the front piece has a top edge and a void area, the void area being approximately equidistant between the first side edge and second side edge and extending from the top edge of the front wall to approximately halfway to the base.

3. The filter holder of claim 1 , wherein the first front side wall and second front side wall are curved toward each other as they approach the base.

4. The filter holder of claim 1 , wherein the width of the front piece is from 1 inch to 12 inches.

5. The filter holder of claim 1 , wherein the height of the front piece is from 1 inch to 8 inches.

6.
