Calculation : to distill approximately 3 liters of water, MKII distiller consumes approximately 750 W of electricity per hour.
If the distillation process takes approximately 2.5 hours, this gives 750 W x 2.5 hours = ~1.875 kWh.
The average price of Kwh is $ 0.18. The total cost for a distillation is therefore: 1.875 kWh* 0.18 = 0.33
=> 0.33/3 = $ 0.11 per liter of distilled water.
Answer : between 10 cents and 13 cents per liter of distilled water.
