Filter sand is a reliable and well-established filter medium for sand filter systems, ensuring that dirt particles are effectively removed from pool water. Its specific grain size allows for efficient filtration while trapping impurities inside the filter. It is particularly suitable for medium to large pools and offers long-lasting and stable filtration performance. To maintain efficiency, the filter sand should be cleaned regularly by backwashing and replaced approximately every 1 to 2 years, depending on usage conditions. In addition to filter sand, modern alternatives such as filter balls or filter wool flakes are available. These options offer easier handling and, depending on the application, can provide even finer filtration. This keeps your pool water clear and clean – for relaxing and carefree moments in your own garden.
