Why exactly isn't the water safe here?

Not sure about “large” RO systems… but I have an under-sink one (have recently moved back to US but still hang around this thread for some reason)

Recommended filter change is once per year and cost $30-100 per set. Electricity use is minimal (only to power the UV lamp). The pump doesn’t actually require electricity… Google it, I was sort of surprised when I didn’t see a cable coming out of the pump.

The whole system wasn’t cheap though >$400

RO takes everything out as you know. Then you have to put some minerals back in, by way of a remineralisation stage.

So you have to entrust a corporation, and their supply chain, to remineralise your water, that is every mL of what you and your family drink every day, in perpetuity.

Some people seem to think RO is the gold standard. But for me I think RO comes down to whether you can stomach this risk.

I think that I saw a thread here a couple of years back where the Government announced that Taipei Water was fit to drink without the need to boil or filter.

Then again, in many countries the old habits stay there “we always boil it”, so why change.

Mind you, as a kid in Australia, in regional areas, drinking water came from a Rainwater Tank out back, and that water of course came from the roof. We didnt die or even get stomach problems. Mind you, we had to replace one tank as it had developed a leak, and when we started to dismantle it we found that the bottom inch or so was just sludge - no doubt why the outlet pipe was a couple of inches up the side. Of course god knows what was in the roof gutters and coating the roof. Non drinking water came from the town water pipes, was not filtered - so we had 3 taps in the kitchen, hot, cold and drinking.

We had our tank on top of the house cleaned, had lots of dirt on the bottom. I think its good idea to get it washed out once a year,
