A pool filter is a critical component of any inground or above-ground swimming pool, and it keeps the water clean and clear for swimmers to enjoy.
A pool filter combines several components, including the pump, skimmer, main drain, filter, and return.
First, a spinning impeller inside the pump sucks water from the pool into the filtration system.
Large particulate matter is captured in this first stage, and the water is fed to the filter, where smaller particles are captured by a cloth or sand filter.
From there, clean water exits the filter and ejects back into the pool.
