Cartridge Filter
Cartridge filters have a greater surface area than sand
allowing for fewer clogs and easier maintenance. They run at lower
pressure than sand which puts less backpressure on the pump, providing
more flow and turnover. Cartridge filters should be cleaned once or
twice a season by simply hosing the cartridge element off. Cartridge
element filters trap debris as small as 10 to 15 microns.

D.E. Filters
Diatomaceous earth (D.E.) is mined and is the fossilized
exoskeletons of tiny diatoms. They are used to coat "grids" in the
filter housing and act as tiny sieves allowing for the removal of debris
as small as 5 microns. Once the pressure rises, the filter is
backwashed just like a sand filter and then "recharged" with more D.E.
powder. D.E. filters trap debris as small as 2 - 5 microns.

Sand Filters
Sand filters in pools are used to extract impurities from the
water by utilizing sand to collect debris as tiny as twenty microns. To
discharge water waste, the sand filter must be backwashed (i.e., running
the filter in reverse).
