Filters

The filtration system is one of the most important components of a pool. It is the main way of cleaning the water as it removes impurities and makes the water suitable for swimming.
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).
