Efficiency Statements
This product is efficiency rated according to NSF/ANSI 44. The stated efficiencies are valid only at the specified
salt dosage and maximum 8 gpm (30 L/min).
4,470 grains/lb (639 grams/kg)
5,510 grains/lb (785 grams/kg)
5,070 grains/lb (634 grams/kg)
An Efficiency-rated water softener is a Demand-initiated regeneration softener that also complies with specific
performance specifications intended to minimize the amount of regenerant brine and water used in its
operation.
Efficiency-rated water softeners shall have a rated salt efficiency of not less than 3,350 grains of total hardness
exchange per pound of salt (based on NaCI equivalency) (477 grams of total hardness exchange per kilogram
of salt), and shall not deliver more salt than its listed rating.
Efficiency is measured by a laboratory test described in NSF/ANSI 44. The test represents the maximum
possible efficiency that the system can achieve. Operational efficiency is the actual efficiency achieved after the
system has been installed. It is typically less than the efficiency due to individual application factors including
water hardness, water usage, and other contaminates that reduce the softeners’ capacity.
Reduction capabilities for specific contaminants verified by test data.
