Hey there, anyone who can't afford to buy distilled water, has a family, and/or drinks a lot of water, this was my solution. I bought a water cooler, the kind where you put the big blue jug upside down on it. You'll have to buy the first jug of water, then when it's empty, I ran my water through a brita filter, poured it into the big blue jug, (you have to remove the cap, and don't worry about trying to save it) doing this until the jug is full. Then place a small piece of glad "press and seal" (NOT REGULAR PLASTIC WRAP) it has to be the PRESS N SEAL! Make sure it's pulled tight, rub your finger around the rim to make sure you have a good seal, then flip it onto your cooler, voila, you now have gallons of free filtered, distilled, whatever else you want in there, water. I used to add liquid trace minerals, so I don't see why you couldn't just add borax if you wanted. Did this for years, for my family of seven; the water was horrible where we lived then.
