Do your own search and call them I tink they know DI water beter than anyone on this board 
but if you still want to drink DI water it is your choice and your life not mine I dont tink you will die of drinking it but maybe it just not the best ting you could do +IMO it dont teaste realy great so why take the risk 
I take the cigaret comparison to show you that because people do it is very far from a good reason to confirn it is good. people do a lot of ting not good for there healt and alway tink healt problem are for other and they are bullet proof but went problem arrive it is another story 
I have not make a blind statement here but I made reseach before to warn you but you are all adult and free of doing wath you want so enjoy you water I enjoy mine
