How can I make my own pure water to drink, cook, and clean?

A very good method for making pure water is a reverse osmosis filter. They run about $150 and mine has lasted over 5 years with no problems. I could not drink the city water and the coffee was yuk. After the RO unit, water is very drinkable and the TDS is about 20 ppm. (TDS = total dissolved solids) Get a good efficient unit and you will never go back to bottled water. Some water companies use these RO units for their purified wate to sell.

I bought a reverse osmosis filter off ebay for $200 and use it for my water to remove the flouride

Distillation makes pure water with no chemical or mineral deposits. You can buy distilled water at the grocery by the gallon and pour it into your own 1/2 litre bottles But distillation takes a long time and a lot of power.

Most of the time, bottled water (Aquafina, Dasani, etc.) is just tap water anyway..

Go in the Kitchen, Pee in a saucepan & then boil it. Put in the fridge let it sit & then drink it up.

First, remember that bottled water is most often the same as tap water in most cities. In virtually all cases, it's not as pure as you think it is - often, there are minerals dissolved in it. Making water from hydrogen and oxygen is dangerous - it creates a lot of heat, so you can't do it that way, except under very controlled conditions. Distillation is the simplest way of taking 'ordinary' water, from any source. That's simple in terms of explanation... You put the water in a pot, get the steam going through a tube, then, direct the steam against a cooler, preferably cold, surface, and collect the droplets. That's as pure as you can get. Of course, the pot will collect all the materials that precipitate out, and that may be very hard to keep clean, but it doesn't get into the pure water. (think of boiling a kettle - after a while, the kettle gets this 'scale' on it, which is almost impossible to remove). Keeping water in a closed container does not necessarily keep it pure - the water begins to taste stale after a while. There are tests for water to determine its purity, but most often these tests are to find what's dissolved in the water, rather than for the water purity.
