Unger HydroPower Resin Bags come packaged in a pail, four bags per pail, for use in an Unger HydroPower deionization system.

Each bag contains a pre-portioned amount of premium-grade, high-capacity virgin mixed-bed resin in a water-permeable material, so it is ready to load without measuring. The pail doubles as reusable storage and a disposal container once a bag is spent.
