No matter how diligent we may be with our pool cleaners, dirt, debris, and other unsavory bits in our pool water can elude our pool cleaning devices.\u00a0\u00a0Luckily, pool water gets pumped through the pool’s filter system where particulates in the water\u00a0become trapped.\u00a0\u00a0A\u00a0swimming pool’s filter system is\u00a0an essential component for maintaining clean, safe water.\u00a0\u00a0What type of filter system\u00a0does your swimming pool use?<\/p>\n

The three existing types of swimming pool filters<\/a> are Sand Filters, Cartridge Filters, and Diatomaceous Earth Filters (DE Filters, for short).\u00a0 Here’s how they each work:<\/p>\n

Sand Filters<\/strong><\/p>\n

\"Sand<\/a>Sand filters, often considered the easiest filters\u00a0to own and maintain,\u00a0use a specially graded sand as the filter media. Water enters the tank through a diffuser.\u00a0 As the water goes down through the bed of sand, the dirt and debris are trapped between the grains of sand.\u00a0 When the water reaches the bottom of the filter, it enters the laterals and is returned to the pool.\u00a0 Sand filters trap\u00a0debris as small as\u00a0approximately 40 microns in size.\u00a0 Anything smaller than 40 microns will often pass through the filter and get circulated back into the pool.<\/p>\n

Cartridge Filters<\/strong><\/p>\n

\"Cartridge<\/a>One of the most popular choices among the\u00a0filter systems\u00a0is the cartridge filter because it can be removed and cleaned with out backwashing, which saves pool-owners time and energy.\u00a0 Cartridge filters use a paper-type cartridge as the filter media.\u00a0 They do not filter as finely as DE filters, but they\u00a0produce about the same water quality as sand filtration.\u00a0 In the past, cartridge filters were considered\u00a0a nuisance to maintain, but over the years, manufacturers have developed newer filters with enough surface area (300-500 square feet) to require cleaning only once or twice each year.<\/p>\n

 <\/p>\n

Diatomaceous Earth (DE)\u00a0Filters <\/strong><\/p>\n

\"Diatomaceous<\/a>DE filters are the most effective\u00a0of the three\u00a0filter systems.\u00a0\u00a0Diatomaceous earth\u00a0comes from\u00a0a naturally occurring sedimentary rock that crumbles easily into a fine powder.\u00a0 The DE filter has plastic grids covered with a plastic type of fabric.\u00a0 A layer of the diatomaceous earth filter powder covers the grids and filters the water.\u00a0 As the water passes through the filter powder, any debris down to 5-8 microns is filtered out.\u00a0 Because the DE is much finer that sand, it is able to filter much more effectively than a sand filter or cartridge filter.<\/p>\n","protected":false},"excerpt":{"rendered":"
