A swimming pool filtration system works by removing dirt, debris, and impurities from the water, ensuring it stays clean and safe for use. The process begins with the pool pump drawing water from the pool into the filtration system. Depending on the type—sand, cartridge, or diatomaceous earth (DE)—the system traps particles as water passes through the filter media. Clean water is then returned to the pool via return jets. Regular maintenance of the swimming pool filtration system, such as cleaning or replacing filters, is essential to keep it functioning efficiently. This process ensures crystal-clear, hygienic water for an enjoyable swimming experience.
