What is the primary purpose of a swimming pool's filtration system?

The primary purpose of a swimming pool's filtration system is to remove impurities and contaminants from the water. This process is essential to maintain safe and clean swimming conditions for users. Filtration systems work by circulating water through a filtration medium, which captures dirt, debris, and micro-organisms, effectively ensuring that the water remains clear and hygienic. Regular filtration is crucial not only for water clarity but also for the overall health and safety of swimmers, as it helps to manage the presence of harmful pathogens and chemicals that can accumulate in the pool environment.

While enhancing the aesthetic appearance, heating water, or adjusting the pool's depth may be associated with a swimming pool, they do not serve as the primary function of the filtration system, which focuses specifically on the purity and safety of the water.
