Yikes... wayyyyyy too much work. If you really need access to a large volume of clean water, buy a cheap RO/DI unit. With (a whole lot of) Butch's help, I bought and put together a cheap RO/DI unit back in... June? I think? and it's still pumping out 0ppm water, and I've been using it for... I dunno... 30 or 40 gallons a week since then? Greatest investment ever.
1-2 liters a month?.... wow!
You definitely dont need a RO
With that little usage, I would just buy a gallon every couple months and be done with it.
Unless you are just wanting to play with the technology of course
Av8tor1, that's what I do right now. I get my water from Winco, but I would like to distill my own water.
riceman, that would be a great option, but I'm more focused on solar distillers because they don't require filters. However, they do need to be cleaned of mineral deposits.
