Hello all,
I would like to add a DI system to my RO unit and I'm having trouble
finding the anion and cation resins.
I'll be building the cartridges myself so I'm looking for just the
resins. I've found lots of refill cartridges that I'm sure I could
open up to get at the contents but I'm thinking it's cheaper if I can
find a source for just the resins.

TIA
Erik
