[1] Product also complies with NSF/ANSI 372.
[2] Product evaluated and determined to comply with efficiency rating requirements defined
by California state laws.
[ER] Softener Efficiency indicates that the softener achieves a minimum of 3,350 grains of
hardness removed per pound of regenerant salt (477 grams of hardness removed per
kilogram of regenerant salt), and also that it uses 5 gallons or less of regenerant
water per 1,000 grains of hardness removed (18.9 liters or less of regenerant water per
64.8 grams of hardness removed).
[HR] Hardness Reduction indicates that the published capacity ratings for reducing hardness
have been verified.
