3 basic types
Three basic types of lters exist for both above ground and
in-ground swimming pools:
- Sand lter
- Diatomaceous earth
- Cartridge
It is important to conrm that the size of lter is adequate
for your pool and your pool pump is correctly rated for your
lter. Generally, the lter cannot be oversized (the bigger the
better). An undersized lter will easily double your chemical
use, double your time spent on water chemistry, and give you
many days of murky water. Very few above ground pools are
sold with an adequate lter, so make sure you double check
yours is the correct size.

Pools with inadequate lters can
either add a second lter or in-
crease the size by replacing an
existing lter. In the case of sand
lters, an upgrade in the media
itself may permit a marginally
sized lter to successfully oper-
ate the pool. Media options will
result in a specic micron remov-
al with a properly sized pump.
