There are several good types of pool filter pumps that are available and choosing the type that is best for your needs depends on several factors. With both filter and sand filtered pumps available, you need to decide which method is best based upon the size of your pool. Generally a sand filtered pool pump is overkill for example on a pool that is 16 feet in diameter or smaller. However for very large pools, or even pools that are in ground they are one of the best types of pool filter pumps available.
