Reduction Capabilities for Specific Contaminants
This product is efficiency rated according to NSF/ANSI 44. The stated efficiencies are valid only at the specified salt
dosage and 5.5 gpm (20.8 L/min):
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.
