It set it and forget it pretty much.  I never think about it except when I need to test the water with a TDS meter about once a year.

Then you just unscrew the housings on each of the four filters, clean it out best as you can, pop in the new filters and close 'em back up.  Just make sure you know what tubes go from whom to whom.  I'd tag 'em and its corresponding filter housing with colors or notes next time so its not so confusing.  The trickiest part is remembering to turn the cold water diverter valve back on!
What bothers me with RO is bacterial growth. I have not researched this aspect. As I believe bleach destroys the RO membrane, using bleach for disinfection of tubes and filters would require a very thorough rinse. So what to do? Use bleach only in the tubes and rinse them thoroughly while replacing the filters as recommended, or rinse and let air dry, some other method? Would love to see some studies on this.

Is there a reason why minerals have to be consumed in the water we drink?  I got to wondering whether salting food liberally with sea salt or Himalayan salt would accomplish the same thing, or whether there's a concentration gradient issue.  I don't remember much from College biology, but the principle that molecules in solution cross membranes in a direction that tends to equalize their concentration on both sides seems as though it might be relevant.

I think if you were to drink mineral-free (say, distilled water) all the time, it would not be good for your body. Acidic, or something.

Or at least mineral free water would lack the benefits of water with e.g. magnesium (which many people don't get enough of anyway).
