The hollow housing supports the board while the buoyancy apparatus is placed in a liquid. The board is a relatively flat and light weight surface that can be easily retrofitted to different housings. The buoyancy apparatus further includes a connector at a first end of the hollow housing for attaching a filter and at least one orifice at a second end for receiving and securing the filter. The kit may also include the filter for preventing at least one impurity from entering the hose. ## Claims ### Claim 1 A buoyancy apparatus comprising: a hollow housing integrally formed with a buoyant board and for maintaining the board near a surface of a liquid when placed in the liquid; a filter; a connector at a first end of the hollow housing for attaching an attachment of the filter; and at least one orifice at a second end of the hollow housing receiving and securing a hose end of the filter. ### Claim 2 (depends on 1) The buoyancy apparatus of claim 1, wherein the filter prevents at least one impurity from entering a hose. ### Claim 3 (depends on 1) The buoyancy apparatus of claim 1, wherein the buoyant board at the first end is convex, at the second end is convex, or at both the first end and the second end are convex. ### Claim 4 (canceled) ### Claim 5 (depends on 1) The buoyancy apparatus of claim 1, wherein the buoyant board comprises at least one dimension that extends beyond the hollow housing to provide additional buoyancy. ### Claim 6 (depends on 1) The buoyancy apparatus of claim 1, wherein the buoyancy apparatus undergoes positive buoyancy. ### Claim 7 (depends on 6) The buoyancy apparatus of claim 6, wherein the positive buoyancy is provided by at least one of: at least one cavity within the hollow housing, at least one cavity within the buoyant board, and at least one cavity within the hollow housing and the buoyant board. ### Claim 8 (depends on 1) The buoyancy apparatus of claim 1, wherein the hollow housing is made of polyethylene. ### Claim 9 (depends on 1) The buoyancy apparatus of claim 1, wherein the board is maintained within 12-inches of the surface of the liquid. ### Claim 10 (depends on 1) The buoyancy apparatus of claim 1 wherein the hollow housing accepts at least one type of the filter. ### Claim 11 (depends on 2) The buoyancy apparatus of claim 2, wherein the filter comprises perforation for preventing the at least one impurity from entering the hose. ### Claim 12 (depends on 1) The buoyancy apparatus of claim 1, wherein the filter has a tubular shape. ### Claim 13 (depends on 1) The buoyancy apparatus of claim 1, wherein the hollow housing comprises a thin poly-foam membrane and the filter comprises a plastic weave. ### Claim 14 (depends on 1) The buoyancy apparatus of claim 1, wherein the hollow housing comprises a PVC pipe and the filter comprises at least one plastic wire. ### Claim 15 (depends on 1) The buoyancy apparatus of claim 1, further comprising a cable coupled to a fastener to secure the filter. ### Claim 16 (depends on 2) The buoyancy apparatus of claim 2, wherein the hose end of the filter is configured to couple to the hose. ### Claim 17 A kit comprising: a hollow housing integrally formed with a buoyant board, the hollow housing providing buoyancy to maintain the board near a surface of a liquid; a filter configured to be received by the hollow housing; a connector at a first end of the hollow housing for attaching an attachment of the filter; and at least one orifice at a second end of the hollow housing receiving and securing a hose end of the filter. ### Claim 18 (depends on 17) The kit of claim 17, further comprising a cable coupled to a fastener to secure the filter. ### Claim 19 (depends on 17) The kit of claim 17, further comprising a hose.
