So I have a nice unit, simple RODI 5 stage and last year I picked a larger filter, sediment and Carbon block.
If I hook this larger two unit filter to my regular unit, would it improve much the filtering capacity?
Mario, are you saying using the 20" prefilters? I use one for my first sediment stage, helps a lot. Otherwise I have to change that out pretty frequently. So it should last longer between changes, but unless you are going through a lot of water I'd say not really needed.
