What is the recommended chlorine level for pool water?

The recommended chlorine level for pool water is typically between 1 to 3 parts per million (ppm). This range is considered optimal for maintaining effective sanitation and disinfection while ensuring the safety and comfort of swimmers. Chlorine at this level is sufficient to kill harmful bacteria and germs, preventing waterborne illnesses, while also minimizing the potential for chlorine-related irritations, such as skin or eye irritation.

Maintaining chlorine levels within this range helps to ensure that the water remains clean and clear without posing risks associated with higher concentrations, which can lead to discomfort for swimmers and damage to pool equipment. This recommendation aligns with guidelines provided by health organizations and regulatory bodies, which emphasize the importance of proper disinfection in recreational water environments.
