Sand filters work by allowing water to cycle through a canister that contains sand. The water flows through the sand with ease, but larger particles are unable to pass through. Once the debris and other particles have been filtered out by the sand, a pump moves the clean water back into the pool.
Is a sand filter better for a pool?
Sand Filters are generally the most compact and more affordable way to filter an in-ground or above ground pool.
