发帖数: 4125 | 5 Your water contains a lot of calcium or magnesium dissolved in it.
Distiller can take them out cheaply, filter equipment capable of doing this
will require a much bigger init investment. A small RO filter unit will take
out some, but not 100%.
Check this out for more info, a home distiller will look like your outside
ac unit. It does drain some water out (so not 100% efficient)
