Swimming Pool Filter Cartridge Replacement for Pentair Pac-Fab Seahorse-500 - R173318.

Pool filter cartridges are used to filter swimming pool water by collecting dirt, debris, algae, oils and other contaminants and filtering them out of the pool water. Cartridge filters have a much larger filtering area due to their design and construction. The pleats on a cartridge allow the filter to run at a lower pressure. As a result, the back pressure on your pool and spa pump is reduced thereby increasing the lifespan of your equipment. A pleated cartridge can trap debris as small as 10 to 15 microns (not visible to the un-aided human eye).

Cartridge filtration has been increasingly popular due to lower maintenance in comparison to old style Sand and most D.E. pool filters. There is no need to "Backwash" a cartridge filter, losing water and chemicals. There is no diatomaceous earth (D.E. - white powder substance) to deal with and the cleaning of the filter cartridge is much simpler.
