Dual or triple DI resin RO unit?


New member
I have a 3 stage RODI unit and was wondering what the advantages and/or disadvantages would be of substituting either 1 or 2 or the other cartridge for DI cartridges?

Not a good idea. the prefilter and carbon are there to protect the RO membrane and you cannot do without them. If anything add additional canisters to the end after the RO for a dual DI.
