The Intex Sand Filter Pump offers many advantages over cartridge filter and Diatomaceous Earth (DE) above ground pool pumps. A sand filter pump is the most efficient and lowest maintenance filter pump option for your above ground swimming pool. The sand filtration media lasts 5 years on average and this saves you money since you will not need to buy replacement filter cartridges every summer. Plus, sand filter pumps tend to last 2-3 times longer than traditional filter cartridge pumps for above ground pools.
