Hayward Pro Series Plus sand filters are the pool professional’s choice for exceptional filtration in a spherical design. This Pro Series Plus filter incorporates many of the advanced features found in Hayward’s Pro Series side-mount filters, delivering high-rate performance for the most demanding installations.

Thanks to its spherical design, the Pro Series Plus evenly distributes the high pressure and stress that are common with solar heating systems, spas, fountains and in-floor cleaning systems. Its impressive underdrain assembly uses 3,800 slots on 10 self-cleaning laterals that ensure totally balanced flow and backwashing. The overall result is a minimal-maintenance filter with greater strength and longer life.
