Distilled water is the purest form of water. Water distiller is the only way that gives distilled water. Countertop water distillers purify the water by 99.7%. Home water distiller purifies the water in 3 steps. In first step, water is boiled. Then, in second step, it is passed through a charcoal. In third step, it is purified again that removes rest of the impurities and gives you purified water.

Your steps two and three don't make any sense. That is not how distillation is described or functions.

are there places where the ground water is so awful, distillation is the only answer? i suppose very salty water might be such a place.
Distillers (for drinking water purposes) hold a special place in the water treatment industry. Their benefit is to produce ultra-high quality water for either drinking, agricultural, or commercial needs. There is also low waste water.
Their downsides include, high energy consumption, low volume production, frequent maintenance, slow production and storage sanitization.
Yes, there are numerous residential units that produce from 1 to 4 gallons per day. Commercial units can produce much high volume butr costs are relative in both purchases and operations.
The 'really awful' syndrom can help justify a distiller, but the worse the water (ie. the more contaminants it removes) the harder the unit has to work and the more maintenance it will require. The cleaner the water entering it, (say RO water), the more efficient it will work.
Removing sodium from ground water is more economically done with a desalination membrane if volumes over a full gallons is needed. Sodium is water soluble but calcium is not. So salt water distillation would be better than trying to soften water through a distiller as far as maintenace is concerned. Acidic solutions (citric acid, vinegar) are needed to break down calcium build up.
Nearly all distillers I see in homes are either not working, poorly maintained or simply given up on. Occasionally, I do see one functioning and well liked by owners.
