Overview An in tank softening pouch for pour over (reservoir) espresso machines. Simply remove the "Oscar" (short for Osmotic Scale Reduction) from the protective packaging, rinse it under some cold water, and place the softener on the bottom of the water reservoir and fill it with water. It is that easy to install. By means of ionic exchange, the "Oscar" replaces the calcium and magnesium ions present in your drinking water, both in their soluble and insoluble forms, with sodium ions. Dimensions 6 inches x 4 inches Material Polyester Texture Functioning Passive, inside tank How it Works To give a better idea of how many gallons of water can be softened with one of these pouches we created a small chart below: # of grains of hardness in your water vs # of gallons of water that can be softened. 5 grains of hardness = 23 gallons can be softened. 7 grains of hardness = 16 1/2 gallons can be softened. 10 grains of hardness = 11 1/2 gallons can be softened. 13 grains of Hardness = 9 gallons can be softened. Note Pouch must be changed at least every 18 months from the date of installation or which ever comes first in usage.
