What makes the Pentair 180007 FNS Plus D.E. Filter the best choice for crystal-clear pool water?

Pentair 180007 FNS Plus D.E. Filter uses diatomaceous earth (D.E.) and will filter out debris from your pool water down to 5 microns and larger in size. This provides you with crystal clear water that sand filters and cartridge filters cannot compare with. Furthermore, this possible because D.E. powder sticks to the filter grids creating a microscopic filtration barrier trapping smaller debris.
