Looks like a good unit, bit overkill on the carbon, but hey youll get good water. I think the top unit is a de-odouriser.
Still, i dont like his sales speak about the Dansani water changing to RODI. First Dansani got shut down over here for that crappy little scam, but secondly. the De-Ionisation resin contains lots of carsonogenic chemicals, thats why Dendro nuts (poison frog breeders) dont use it, because the little amphibs go nuts scratching themselfs.
