DETAILED DESCRIPTION

[0020] As discussed above, embodiments of the present disclosure relate to a pool water filter device and more particularly to a secondary pool filter device as used to improve the filtration of pools. The secondary pool filter device is configured to capture any dirt, debris, particles, algae, bacteria, and pathogens that are not trapped by a primary pump filter.

[0021] Generally, the secondary pool filter device is a secondary water filter that attaches to water jets of above-ground pools. As water moves through the primary pump filter of a swimming pool and then back to the pool through the water jets, the secondary pool filter device captures any dirt, debris, particles, algae, bacteria, and pathogens that were not trapped by the primary pump filter. This additional filtration provides improved water cleansing that is of recognized need, reducing the frequency in which manual cleaning of a swimming pool is required, and saves in both time and cost of such manual cleaning. The secondary pool filter device captures dirt, debris, and other particles that bypass filtration by a primary filter of a swimming pool water pump. The secondary pool filter device helps swimming pools maintain a pleasant, recreational image and use.

[0022] The secondary pool filter device comprises a mesh screen, a filter pad and a filter sleeve. The filter pad of the device consists of an interior layer of cotton encased withing a felt fabric. The meshed screen is completely encased within the filter pad. The filter sleeve may be comprised of a polyester material and the open end of the sleeve features a cinch tie. The filter sleeve may be secured around the filter pad during an assembled condition. The filter sleeve may be placed over a return jet within an aboveground pool, and the cinch tie is used to secure the filter sleeve to the return jet. Additionally, the device may be fastened to a pool vacuum. The secondary pool filter device may be reusable and can be easily washed to remove any substances trapped within the filter pad and filter sleeve. The secondary pool filter device makes swimming pool water cleaner than is ordinarily achieved by current filtration systems. The secondary pool filter device eliminates the time and labor cost of manual collection of dirt, debris, and other particles that escape primary filters. Additionally, the secondary pool filter device can help prevent growth of algae on swimming pool walls and floors.

[0023] In a most preferred embodiment, the mesh screen of the secondary pool filter device is made of polyvinylidene fluoride (PVDF). Molded in a rectangular shape with evenly spaced apertures through its structure, the mesh screen measures approximately thirteen and one-half inches in length by seven and one-half inches in width by a sixteenth of an inch in thickness (13½″×7½″× 1/16″). The mesh screen is encased within a filter pad preferably comprising two-layers. The filter pad is approximately fourteen inches in length by eight inches in width, and approximately one-quarter of inch thick (14″×8″×¼). The inner-lining of the filter pad is made of cotton foam material contained within an outer-lining of felt. For containment of the filter pad is a filter sleeve with one (1) closed end, measuring approximately nine inches in length by six inches in width by two inches in depth (9″×6″×2″). A securing cinch tie is featured at the open end of the filter sleeve. The filter sleeve also provides additional filtering capabilities.

[0024] A method of use may be as follows: a user may roll the filter pad of the secondary pool filter device into a cylinder, and then place the filter pad within the filter sleeve. The cinch tie (or other suitable means) from the filter sleeve may then be used to secure the secondary pool filter device over a return jet of an above-ground swimming pool. After application, the secondary pool filter device provides additional filtering when water is returned to a swimming pool. With this additional filtration, all undesirable dirt, debris, and particles that were not removed by the primary filter will be kept from returning to the water, and so will algae along with many bacteria and pathogens. As a result of this secondary filtration, the user of the secondary pool filter device will not have to manually clean the pool as often, and will not have to purchase pool-cleaning materials as often, too.
