iFilters MED-CAT-025 1/2 cu ft Softener Resin: standard cation resin

What it does for your water

The iFilters MED-CAT-025 1/2 cu ft Softener Resin is replacement cation resin in a 1/2 cu ft quantity.

A cubic foot of standard softener resin is rated about 32,000 grains at full salt and about 24,000 at an efficient setting, so 1/2 cu ft is about 16,000 grains at full salt, or 12,000 at an efficient setting.

Standard 8% crosslink resin is what most residential softeners ship with.

Replace the same volume your tank holds and leave the free space above the bed the maker calls for; an overfilled tank can't backwash.
