Pool filters remove dirt particles and impurities in the pool that would otherwise accumulate very quickly and create an unsanitary environment for people. Not only do filters remove impurities, but they help regulate the chemical distribution in the pool to maintain the right balance needed for swimming conditions. It is important to clean and change these filters regularly.
