What is the main purpose of a pool filter?

The main purpose of a pool filter is to remove debris and contaminants from the water. Pool filters play a crucial role in maintaining water clarity and safety by trapping and eliminating particles such as dirt, leaves, and algae, as well as microorganisms that can affect the quality of the water. This process not only helps keep the pool visually appealing but also contributes to the health and hygiene of the swimming environment.

While maintaining water temperature, circulating chemicals, and providing aeration are all important aspects of pool maintenance, they do not reflect the primary function of the filter itself. The filter's ability to keep the water clean is vital for preventing issues such as cloudy water or disease transmission, making effective filtration essential for any commercial pool operation.
