Active Pool Supply offers the most popular replacement DE filter grids, cartridges and elements to make sure you find what you need. Traditional DE grids with bottom manifold use eight full grids and the top manifold version uses eight grids as well, but seven of them are full and one is partial to allow room for the standpipe. Additional DE options include cartridge elements for Sta-Rite filters and the latest in DE filters, the Quad DE cartridge elements from Pentair - providing the easiest to clean filter on the market.
