What it does for your water
The US Water Filters 0.25 cu ft Softener Resin is replacement cation resin in a 1/4 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 1/4 cu ft is about 8,000 grains at full salt, or 6,000 at an efficient setting.
Standard 8% crosslink resin is what most residential softeners ship with.
Buy the volume your tank was built for. The empty space above the resin is there on purpose: the bed needs room to lift during backwash.
The listing also gives model 0.25 cu ft; resin 1/4 cu ft.
The listing gives dimensions of 2.5 x 14 x 16 inches; 12 pounds.
