View Full Version : rodi replacement filters

08/12/2014, 07:58 AM
I have a 5 stage RODI unit. I haven't changed the filters in a long time and don't remember what they are. Of course there is the RO membrane and DI housing which leaves 3 other filters.

I have 2 Pentek P5 - 5 micron sediment cartridges and 1 Pentek C1 Carbon-Impregnated (didn't mean to get racy) Cellulose cartridge. I imagine some form of these are what's in there now, but maybe not.

What belongs in there. I do not use a ton pf water so they last pretty long.

Any recommendations?

I'm on well water with an iron filter and water softener before the rodi.

does your system have two DI stations, or one?
I suspect you should have
sediment 0.5
carbon 0.5
carbon chor plus hi chlorine removal
mem-sp-90 membrane with new flow restrictor
silica buster high capacity color indicating
