Quote from Azrael_the_Cat :
Alkaline water is so lightly Alkaline it has no impact on acids in the esophagus. You should look into what it means to have a PH of 7.5 or 8 when mixed with liquid of a PH of 3 and understand how the chemistry works.
We all make Alkaline water when we add a pinch of baking soda to it.

Your comment demonstrates a profound lack of knowledge on this topic. Alkaline water is not a standardized term that means a specific PH range. I can make Alkaline water of various PH and it's all still considered "Alkaline water", as long as the PH is greater than 7. Alkaline water is by definition, a water imbued with alkaline properties - with the ability to neutralize acidity. I understand the chemistry just fine, as such I wouldn't make an erroneous statement that alkaline water is definitionally a specific "lightly Alkaline" PH range. Yup, baking soda is an easy way to make water alkaline.

Quote from Artc8888 :
PLEASE Note the replacement filter will cost you $63 (set) + RO filter ($52)..... also, i prefer to have a clear canister, where I can visually monitor the degradation of the filter....
Please don't buy a clear canister. Lived in a third world country where this was touted as a feature but the filter was above the sink, next to a window. The filter went from white to green in a couple of months due to algae growth with exposure to sunlight.

I think anyone with common sense knows this.
This is 'Murica, where people shoved slices of raw potato into their socks to ward off Covid while refusing the vaccines available.

About 30-40% of the country gets hilariously awful (and often dangerous) medical advice from Faceplant Mom Groups.

Common sense is not even remotely common any longer.

Quote from fieldcar :
Reverse osmosis (RO) systems remove nearly all dissolved minerals from water, including beneficial ones like calcium and magnesium. This results in water that is very pure but often tastes flat or bland due to the lack of minerals. Additionally, the absence of minerals can make the water slightly acidic, with a pH typically between 5.0 and 6.5.
To improve taste and balance pH, an alkaline filter is added as a final stage in some RO systems. This filter reintroduces essential minerals such as calcium, magnesium, and potassium into the water. Doing so raises the pH to a more neutral or slightly alkaline level (typically 7.0–8.5), enhances flavor, and gives the water a smoother mouthfeel.
In short, the alkaline filter prevents flat water by restoring minerals removed during RO filtration, making the water more pleasant to drink and less acidic.
I like my water tasteless. I have had the tankless system from the same company for nearly 2 years, at first I got the Alkaline version, I hated the after taste of calcium so I replaced it with the neutral one, like it much better. Recommend getting the regular one and if you don't like the taste only the consider gettin the Alkaline addition.

How do these plants (in natural environment) get this pure, distilled water on which to thrive?
Carnivorous plants are carnivorous because they live in nutrient depleted boggy soils and acquire nutrients from the insects they trap and dissolve in the various mechanisms different genera and species employ.

Thinking about getting an under sink RO filtering system for a house we are moving to. It has well water. Can someone please recommend a good under sink RO system for well water?
Did the well water test for high mineral content or something? Well water doesn't inherently need filtering like this. Our well water is very nice for drinking.

The placebo is strong with this one 😄
If a placebo is effectively causing positive change, that is effective medicine by definition. The mind can trigger physiological changes in the body, as it is a physical part of the body itself which interacts with the rest of it chemically.

Alkaline water tastes crisp. Nothing like a refreshing glass of iced alkaline water

I have iSpring RCC7AK, 6 stages. For my well water works great. My well water has ~600 ppm, ispring reduces it to 40ppm
