The right pool filter cartridge depends on the filter model, cartridge length, outside diameter, end cap style, center hole size, square-foot rating, and part number. A cartridge can look close and still be the wrong fit, especially when comparing similar filters from the same manufacturer. Before ordering, check the label on the existing cartridge or filter tank and compare all measurements carefully. If you are unsure which pool filter cartridge, DE grid, filter bag, or replacement element fits your system, contact Aqua Terra Backyard with photos of the old cartridge, the filter model, and any part numbers printed on the filter or tank. We can help you narrow down the correct replacement before you buy.
