DE Filters

Diatomaceous Earth (DE) Filtration Systems provide the clearest sparkling water, efficient flow and the largest cleaning capacity for pool and spas compared to sand and cartridge filtration systems. That is because the DE filter removes particles that are as small as 3 –5 microns. Even though the human eye can’t see any particles that are less than 40 microns, increased quantities of large microns can have a very noticeable effect on water clarity. DE filters can filter larger areas, which means longer periods of time between cleanings. Also, DE can be replaced with alternatives such as zeolytes. There are some disadvantages to a DE Filter. The initial cost and long-term operational cost of a DE filter is not the most cost effective medium on the market. DE filters require backwashing every few weeks. DE filters as well as sand filters requires plumbing a separate sewer line to an area that the water can be backwashed to.
