What is the purpose of pool filtration systems?

The primary purpose of pool filtration systems is to remove impurities and contaminants from the water, ensuring a safe and clean swimming environment. These systems function by circulating water through filters that capture dirt, debris, algae, and other pollutants. By maintaining water clarity and cleanliness, filtration systems play a vital role in the overall health of the pool, contributing to the effectiveness of sanitizers and chemicals used to treat the water.

While providing water circulation and flow is also an important function of filtration systems, their main focus is on purifying the water. Enhancing aesthetic appeal and increasing water temperature are not direct purposes of a filtration system, although clear water can contribute to the overall beauty of a pool. However, temperature control is managed separately, typically by heaters or solar covers. Thus, the filtration system's core objective remains the removal of contaminants, reinforcing the importance of keeping the pool water safe for users.
