About this filter
One of the most common spa sizes there is. A pair of our PRB25-IN cartridges lets you rotate: one in the tub, one soaking in cleaner.
- Replaces Pleatco PRB25-IN, Unicel C-4326 and Filbur FC-2370
- Open core design means rinsing is needed less often than with basic media
- Two in the box for an easy clean-and-rotate routine
