    The water conducibility of "deinized water" is +/- standard betwen .2 to .05 microsiemens (5-20 megaohm). note you can't obtain high resistivity because H2O is a polay molecola... and it conduce current.
    But remeber than the filtration is important too in HC .1 nicron is the standard.
    The productions way are different, if you need only few liter day the simply way is mix bed resin (better ina reciluation system), if you need high water flow the best system is Osmosis + mix bed resin
