RO/DI question

[ElusiveKumquat]

So I have an Aqua FX Dolphin RO unit. I would like to also run DI for my water. Can I use any 2 chambered unit for double DI? Or is there a specific unit for DI only?

I may go with something like that. But I have access to many used RO units but I'm just wondering will DI cartridges work in those as well? Or does DI only work if it's in a specifically designed unit for DI only?

DI cartridges fit in normal 10" canisters.
