We used RO to pretreat the steam distilled water in the research lab eliminatine the need to descale the water still. For research we still wanted the distilled water to remove the last traces of mineral.

I guess the filter would remove most of the minerals and chlorine and other icks (I don't think any home filter does 100%), and boiling would take care of the microbial concerns. However I know that's not the same as the distillation process, which makes the water truly pure, but it might work as a stop-gap.
