The DI aspect is mostly all marketing hype. The filter is not nearly large enough to allow the water to remain in contact with the DI beads to make any significant difference. And if it were they would be depleted and useless after the first gallon.
DI works just fine when done properly but it is VERY expensive if it is done correctly. Those DI resins are $$$$ to replace. They only used where water is very expensive and the reject water from RO systems eats into the overall cost to produce a gallon of water OR they trying to produce water so pure it has absolutely nothing else in it.
If you are unable to collect rainwater the next best long term economical solution for most people is a basic RO system. What you need to do is present the facts to your folks and convince them that a small RO system would be cheaper in the long run than buying water from the RO dispenser and provide excellent water for your plants and their morning coffee..
Is that a Nepenthes in your pocket or you just happy to see me?
I have been using a Brita filter for 13 years and have had no problems with my plants. But once again, I live in a rural area and the tap water, I believe, is clean to begin with. Of course, I have never had it tested so I can't claim that the Brita is what has helped.
Wonder what will happen if some extremists ever get their way in our govt. and sterilizing agents are added to our water supply to cut our population down? Just heard this today, apparently John Holdren, recently appointed science czar, by our president, believes this should be done if our population gets out of control, along with other means to control it, albeit extremely, extremely unlikely that it would ever happen. Don't wanna stir the political pot, so don't argue politics over this (posted this comment for a scientific view)....but...
What would happen to my Nepenthes? LOL! No more seeds, guess all tissue culture, and cuttings or would they be unaffected?
Besides, no "safe" agents of this sort exist as of yet.
