I prefer the taste of RO filtered water. Obviously the system removes many impurities from the water, but I'm not sure how one measures the benefit of drinking filtered water -- that probably depends on what you'd be drinking if the water weren't filtered. Each of us ingests plenty of impurities in our food and in the air we breathe, so...

RO and Distilled water are probably not any healthier than tap water. You do need some of the minerals that are dissolved in water, and both methods remove those minerals. They might taste better, but that's a personal preference thing. When tap water tastes like chlorine, I'll drink filtered or bottle water, but distilled water tastes off to me, because I'm used to tasting the minerals in normal water. Most bottled drinking water has minerals added back into after the purification process. Often the difference in flavor from one brand of bottled water to another is the differences in the minerals in the water.

The incremental gain of a better quality water over tap water

There are those that drink only bottled water. Etc.

You keep saying this like it's a fact. Evidence?

Generally unnecessary to filter tap water in most parts of USA, Canada, AUS, NZ, UK, Scandinavia, etc.

There are a few exceptions - i.e. Like my car, I prefer unleaded vs. the stuff the serve in Flint, MI.

In general I feel safer drinking tap water than bottled water. Most jurisdictions have very stringent testing standards for tap water. Its tested daily, weekly, monthly. Bottles water has far less testing on it by the company, and vert little little independent oversight / testing by regulatory agencies.

Nothing wrong with activated carbon or RO membranes. Generally. Except most people I know keep the filters way too long. Or go away for 2 weeks and leave the system to stagnate. Then they keep using it after it has bio-growth. Usually not harmful but pretty pointless.

I am also not a fan of drinking from plastic bottles. Particularly if the bottle ever got warm. I'm trying to cut down on my VOC intake.

P.S. At least we are not having the discussion about tap vs. bottled vs. filtered water instead of the magical properties of ASEA Water. Anyone remember that shitefest? https://forum.slowtwitch.com/...string=asea#p3807244

bottled water is the devil

What I notice is that the water tastes the same wherever I go using my Berkey. Even at home, there are times when they flush the lines or do something where the residents to the town notice that the water tastes different.

The incremental gain was my mocking all the incremental gains we seek elsewhere.

I know tap water has chlorine, etc and the Berkey takes out the bad and leaves in the good. A problem with RO water is we need some minerals in the water or it could leach us of minerals.

So a word salad is your evidence?

Like the picture provided above, I have the same filtration system (white Berkey filters). One can see the filter and I taste the difference.

Enjoy your tap water. It seems to be working for you. Don't change.

What is the purpose of these pictures for comparison?

Are you implying this picture demonstrates your tap water is good, bad or is it just a piece of artwork?

That picture tells me almost nothing.
