Be sure to run at lest 50 gallons threw before you attach the DI stage, don buy into the high cost RO units cause they are pretty much the same, as long as the sediment filter and Carbon blocks are under 5 microns you should be good, i got mine 5 stage from ebay bulkreef supply.com for half the cost of those other so called high end and i couldn't be happier.
