- The System 3 Modular Media Filters handle 2-3 times more dirt than other filters to deliver maintenance-free performance for up to a full season.

- Featuring perfectly balanced flow and an integral manifold design, these filters are engineered to deliver the ultimate in labor savings.

- System 3 Modular Media Filters are ideal for inground pools, inground hot tubs and water features.

- Water flows very efficiently through System:3 Modular Media Filters filters allowing the use of smaller pumps or lower pump speeds to minimize energy use. And when consumers rinse cartridges rather than backwash, they can significantly reduce water use, too.
