The reverse osmosis water the other post was refering to can be received either by you personally buying a machine/filter to make the water, or you can get it out of most water dispensing machines at a grocery store for ~30 cents/gallon.
The benefits of your own machine are that you do not have to lug a large container to the store every time you run low on water. However, the disadvantage is that between the cost of the machine and the necessary filter changes it will cost you a bundle of money in the short-run.
The benefits of the store-bought RO water is basically the opposite of the alternative. It is reasonably cheap. But, you have to lug a large (or several) container to the store when you run low.
