The filter is one of the essential components for a pool to work properly. There are different types of filter: sand filters (the most popular as they require little maintenance), cartridge filters (the cartridges have to be replaced once a year) and diatomaceous filters (the most expensive, as their high performance filtration system even removes dirt not visible to the naked eye).
Its power will depend on the size of the pool and amount of water that has to go through the filtration system. A pump’s casing fills with water to create a vacuum, which allows the water to flow through it.
