Cartridge Filters are an excellent option for above ground swimming pools due to their low maintenance and cost-effectiveness. Cleaning is simple with a standard garden hose, making upkeep effortless. Unlike sand and D.E filters, cartridge filters eliminate the need for backwashing, thus preventing water and chemical loss. Their efficient design ensures long-lasting performance, saving both time and resources for pool owners.

Saltwater pools are easy to maintain, offering a more natural swimming experience, but can be corrosive to some pool components so you would need a swimming pool that is specifically made for saltwater use. The Saltwater 5000, Saltwater 8000, Saltwater LX, Saltwater Titan, Saltwater Aurora, and Intrepid are all warranted for saltwater use and can be found on the following page: Saltwater Pool Models

Investing in a specifically designed pool helps prevent corrosion and ensures your pool remains in top condition for years.
