Try Evian versus the waters sold by Coca-Cola (that are tap-water equivalent) and you can really feel it.

If I were faced with the sludge coming out of the pipe in some places, I’d stock up on Brita pitchers. Here, I never go out of my way to filter it.
(That said, it's never bothered me to drink tap water wherever I go, and acclimate quickly. I think the bottled water trend is insane.)
There almost certainly is a taste difference. The mineral content is likely different, and the plastic from the bottle can have an influence, too.
I can definitely taste a difference between our (Pur-filtered) tap water and the cheap bottled water we get.
When I was a kid, I wouldn't drink Aquafina (or Dasani) because they tasted plasticky. I attributed it to them using the same plastic for Cola bottles, without the overpowering flavors to mask subtle tastes from the plastic. I'm not as picky now, but my taste buds have gotten less sensitive and it's also possible they fixed the issue.
Plastics used in water bottles are not water soluable.
Is there ANY hard evidence of harm to human health from ingesting minute quantities plastic dust vs any other kinds of dust?
Most plastics are chemically and biologically inert. That is why they don't break down in nature.
Where is the evidence that they react in the body to cause harm?
A water bottle is not your vinyl shower curtain. It is made of PET or maybe PE. Neither are biologically active.
Polyamide ( nylon ) in water filters is non toxic. You could probably eat a teaspoon of fine nylon powder a day suspended in water for years with no health effects because it would just pass through the body without reacting, mainly excreted with feces. Your intestines are not going to absorb insoluble plastics into your blood. The quantities found in water bottles are far, far, less than a teaspoon.
Is there any study that purports to find a significant quantity of polyamide or PET or PE in blood???
It really seems there is a media generated mass hysteria around safe plastics. Not all plastics are the same. Plastics used for food or drink application are typically PROVEN safe from decades of study. What are we all worried about then?
For example there was a time when publicity recommending cigarettes to pregnant women was a thing.
I still quite a fan of this even when I drink water from plastic bottles when I am on the road.
Cost wise I found it evens out per bottle when compared to buy cheap bottled water from e.g. Aldi. However, it is not necessary to carry water bottles anymore which already is quite an improvement and well worth the money.

Hot water and an acidic beverage running through plastic every morning. Doesn’t seem good.
It seems once the water is boiling inside it’s vigorous enough to kick particles out with the steam. (And it’s hard to refill without occasionally spilling on the cord which ultimately killed mine)
I ensure my little boy uses only metal water bottles.
Aluminium bottles are always coated with plastic in the factory, which flakes off and usually isn't really better than plastic-bottle-plastic, sometimes even worse (containing PTFE, BPA, ...). As soon as the coating is gone, aluminium will dissolve in the water, and aluminium salts are known to be "not good", in addition to the influence on taste. Same for copper, in addition to the hassle to keep copper clean. Steel bottles are better because proper kitchen-quality stainless steel (the one with Molybdenum in it, in addition to Chromium and Nickel) doesn't leech out into common drinks (including salty hot broth, which would stain CrNi steel) and doesn't need inner coating.
First of all, at least where I live, tap water has chlorine. Which seems to carry some risks (see, e.g. https://pubmed.ncbi.nlm.nih.gov/12594192/).
Secondly, my building has copper and PVC pipes, which are also suspected of having some adverse health effects.
Thirdly, where I live, sometimes (about once per month) tap water comes out brown. Authorities typically say that it's fine to drink, and I suppose they analyze it and it conforms to some official standard, but I'm not going to drink or give anyone brown water. And that also makes me think that maybe the days it doesn't look brown to me, it might be also somewhat brown, just maybe not brown enough for me to notice.
Maybe I'm wrong and plastic from bottles is much worse than these things, but I don't think you should be so amazed that people can prefer bottled water. At the end of the day, it's a matter of picking your poison... with incomplete information.
If some of the contamination is "pre bottling" then the issue may be way more pervasive than just bottled water.
i wonder if it is more of an issue for large-scale filteration or even for the ones used at homes. anyways, for our generation and the next microplastics are here to stay (just check the search results here https://hn.algolia.com/?q=microplastics)

Too different from the title. And the other comments seem to have been written without reading the text.
Is this inevitable with a polyamide membrane RO system or is this wear and tear with insuficient maintenance/ part replacement?
It sounds like it doesn't matter:

Here still lead pipes are being discovered in old building, which has proven to lead to significant issues in Brain development of children.
Also often other residue is found of farming & medicine and other things seeping into the ground water.
So sadly finding clean & good water is not easy, bottled or tap.
