A Bestway sand filter setup is a water filtration system used to clean swimming pools. It uses sand as a filter media to trap dirt, debris, and other contaminants from the pool water. Sand filters are a popular choice for pool owners because they are relatively inexpensive to purchase and maintain, and they do not require any chemicals to operate.
Sand filters work by passing the pool water through a tank filled with sand. The sand traps the dirt and debris, and the clean water is then returned to the pool. Sand filters need to be cleaned periodically to remove the trapped dirt and debris. This can be done by backwashing the filter, which reverses the flow of water through the filter and flushes out the dirt and debris.
