How Does A Pool Filter Work?

  • A pool filter's main job is to make sure you are swimming in clean and clear water.
  • The pool pump cycles the water through the system, which passes into the pool filter.
  • The debris and particles are captured inside the filter, which allows the clean water to flow back through the system into your pool.
  • There are three types of filters: Cartridge, Diatomaceous Earth (D.E.), and Sand.
  • Cartridge and D.E. filters are required to be cleaned before the start and at the end of the busy swimming pool season.
  • Please give us a call if you have questions deciding what type of pool filter and what size you want.
