Inground pool filters are responsible for removing debris and particulate that could contaminate your water and make your pool unsafe for swimmers. Once an inground pool filter is up and running, your water will remain crystal clear and free of debris. Our large selection of filters for inground swimming pools provide clean, sparkling water season after season and are designed to meet the needs of any size pool.Filters for inground pools are equipped with more feet of piping and plumbing, and they typically have multiple skimmers, jets and other suction lines for optimal performance. The design allows this type of filter to manage a large amount of water, and can filter between 20,000 and 40,000 gallons of water about two to three times a day. The inground swimming pool filters at Pool Express are all from heavy hitters in the swimming pool equipment industry. Top brands like Hayward, Pentair, Jandy and the energy efficient EcoFilter have maintained the reputation of efficiency and reliability year after year.

Sand filters for inground pools are considered a foolproof method to clean, clear water. Water is forced through a media bed of sand where dirt and debris are removed and trapped around the fine grains. They can filter particles between 20 to 40 microns in size. Diatomaceous Earth (DE) filters are perfect for filtering out the smallest particles, as small as two to five microns. Tiny diatoms coat the filter grid for an efficient and thorough cleaning method. They do require backwashing when they need to be cleaned, but are notorious for delivering pristine swimming pool water.

Cartridge filters are easy to maintain, economical, and low maintenance. These swimming pool filters do need to be disassembled and cleaned with a hose regularly during the swim season. They typically filter particles as small as 10 to 15 microns, and are a smart choice if you want to cut maintenance time on your pool.
