Description

The Pentair Dynamic Series III R172523 cartridge filter is built for efficient, high-flow filtration in spas, hot tubs, and small pool systems. With 25 square feet of filtration area and a flow rate up to 100 GPM, it delivers reliable water clarity while maintaining strong system performance.

Its top-load design allows quick access to the cartridge, making routine cleaning and maintenance simple and fast. The integrated chlorine/bromine dispenser adds convenience by helping maintain proper sanitizer levels without additional equipment.

Constructed from durable, heat-resistant materials, this filter is designed to withstand demanding spa environments. The compact vertical footprint and 2" plumbing connections make it ideal for installations where space is limited but high flow is required.

Pro Tip

Keep a spare cartridge on hand so you can swap and clean later—this keeps downtime to a minimum and maintains consistent filtration.

Installation Tips

Install vertically on a stable base with 2" plumbing connections. Ensure adequate clearance above the unit for cartridge removal. Follow manufacturer flow and pressure guidelines.
