Cartridge filters: Unlike Sand and DE filters, Cartridge filters do not need backwashing. Cartridge filters remove particulate down to about 8-10 microns in size
DE (Diatomaceous Earth) filters: For the best possible filtration, a DE filter is the choice for you. However, DE filters also require the highest level of maintenance. DE filters remove debris down to about 3-5 microns in size
Sand filters: The most common form of pool filters are sand filters. Sand filters remove debris down to about 25-30 microns in size, but by using advanced filter media such as Zeo Sand, sand filters can remove debris down to about 5-8 microns in size
Filter Valves: Filter Valves are used with Sand and DE filters to make the backwash and cleaning process easier
