filter is what removes the fine particulate from the water and
enables you to swim in a clean clear pool.

filters use a specially graded sand as the filter media. The water
enters the tank through the diffuser. As the water goes down
through the bed of sand, the dirt and debris is trapped between the
grains of sand. When the water reaches the bottom of the filter,
it enters the laterals and is returned to the pool.
filters filter out debris down to about 40 microns in size.
Anything smaller than 40 microns will probably not be filtered out.
filters use diatomaceous earth as a filter media. The DE filter
has plastic grids covered with a plastic type of fabric. A layer
of filter powder called Diatomaceous Earth covers the grids and does the
water passes through the filter powder, any debris down to 5-8 microns
is filtered out. Because the DE is much finer that sand, it is
able to filter much more finely than a sand filter.
FILTERS (also sold as Modular Media)
filters use a paper-type cartridge as the filter media. They do
not filter as finely as DE, and in our experience produce about the same
water quality as sand filtration.
filters used to have a bad reputation as a nuisance to
maintain, but manufacturers have come up with newer filters
with enough surface area (300-500 square feet) to need
cleaning only once or twice each year. This makes the
maintenance issue a plus with these filters.
