Sand filters are a key component in maintaining clear and clean pool water. They use sand as the filtration medium to remove debris, dirt, and impurities from the pool water. Sand filters are known for their simple, cost-effective, and efficient operation, requiring minimal maintenance compared to other types of pool filters. They work by passing pool water through a bed of sand where the particles are trapped and the clean water is returned to the pool. Sand filters are ideal for pools of all sizes and are commonly used in both residential and commercial pools. The advantages include low operational costs, long-lasting performance, and a robust design that can handle high flow rates. Sand filters are suitable for all pool types, including above-ground and in-ground pools, and are a popular choice due to their proven efficiency in large-scale pool operations.
