Abstract: A filter is disclosed for installation in a pool filter basket. The filter includes a filter screen having an edge, a first band, partially affixed to the filter screen near the edge and partially free, and a second band opposed to the first band, partially affixed to the filter screen near the edge and partially free. The filter is installed by placing the filter screen inside the filter basket, pulling the edge, the first band and the second band over the rim of the filter basket, forming a lip and the first band is pulled across the second band and the second band is pulled across the first band, securing the filter to the filter basket. In an alternative method of installation, the filter screen is placed inside the filter basket, but the free portion of first band and the free portion of the second band are on top of the filter basket, going under a filter basket handle if the filter basket has a handle.
