Spa filter cartridges are used to filter spa water by collecting dirt, debris, algae, oils and other contaminants and filtering them out of the 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 spa pump is reduced thereby increasing the lifespan of your equipment.

This is a filter for Hot Spring Highlife NXT and Highlife models.
