>>11434149It does more than reduce deposits - one of the primary concerns with any "single filter" system of any kind - including distillation - is that it only applies a single "selection" criteria to whatever you're filtering.
In the case of water in a desktop distiller, you're not selecting for only water - you're selecting for anything with a boiling point at or somewhat lower than water. "somewhat lower" includes a bunch of organic compounds which you don't want. This depends on solubility and boiling point of the compound, but chemicals like benzene and toluene will cross very simple distillation setups. Home distillation setups are generally massively oversold on their ability to get rid of VOC's.
Industrial-grade distilled water doesn't have this problem because it isn't strictly distilled, it's fractioned, and that's generally after being run through other filtration stages.
Activated carbon is terrible at getting out certain metals and halogen species, but it's absolutely fantastic at getting rid of organic compounds.
Activated carbon + simple distillation is a pretty damn hard setup to beat for drinking water, and everything about it is apocalypse friendly.
