What is the primary purpose of filtration in pool maintenance?

The primary purpose of filtration in pool maintenance is to physically remove suspended particles from the pool water. This is crucial for maintaining water clarity and ensuring a safe swimming environment. Filtration works by circulating water through a filter media that traps debris, dirt, and other contaminants, allowing clean water to return to the pool.

While filtration systems contribute to overall water quality, they do not completely destroy all bacteria and viruses. This is typically managed through disinfection processes, such as the use of chlorine or other sanitizers. Additionally, accumulating diatomaceous earth is specific to certain types of filter systems and not a general function of all filtration processes. Therefore, the most accurate answer focuses on the filtration system's role in removing physical impurities, which is essential for maintaining clean and clear pool water.
