    Sand Filters are generally the most compact and affordable option to filter an in-ground or above ground pool. Sand Filters use specially designed Pool Filter Sand that removes the dirt and debris as water pushes through the media. The cleaned water then flows back into the pool out through the bottom end of the filter. In a Sand Filter back-washing occurs once water flows out through the
