Swimming Pool Filter

A pool filter is a component of a pool's filtration system that removes dirt and debris from water. A pump pulls water to the filter, the filter removes dirt and debris, and then clean water is returned to the pool through return jets on the pool walls.There are three main types of filters to choose from to keep your swimming pool sparkling clean all year round. These include the cartridge filter, diatomaceous earth (D.E) filter and sand filter. Sand filters and cartridge filters are the most popular of the three because they are small and inexpensive.The pool filter's job is to capture debris, dirt and bugs that end up in the pool, thus keeping the water clear. The filter also aids in water circulation, which is key for healthy pool water. Circulation helps evenly distribute pool chemicals that kill bacteria and prevent it from forming.
