No, they're not the same thing. Now I'm drawing a blank on what makes them different. Mainly, I'm contributing to this post to suggest that people think about more than drinking water. Tap water is typically treated with chlorine. Chlorine attaches to the same receptors as iodine, so even if our food intake provides adequate levels of iodine, the levels of chlorine in water can elbow the iodine to the side.
For my drinking water, I use a brita filter. It's fudgy on the chlorine issue. I think it says 'removes chlorine taste'. I reckon if it removed the chlorine altogether, it would just say 'removes chlorine.' Where I live, the tap water practically smells like a swimming pool, so just removing the taste is an improvement. Reverse osmosis filters are the filtering system of choice based on the reading I've done. Filtering your whole house is spendy. There was detailed information about water in Dr Brantley's book The Cure.
Any water that has been processed to remove impurities is purified water....What gets removed depends on what's being used to do purification.....
Distilling water is a way to do this......You heat it until it vaporizes, and then run it through a condenser to recondense it....
In so doing, when the H2O goes vapor, it leaves stuff in it behind....and the result is a very pure water...
Theoretically, pure water should have a pH of 7, that is, neither acidic or alkaline...
In the case of distilled water (and a lotta other water) it picks up CO2 from the air, and winds up being just a tad acidic...
In the marketplace, what's sold as purified water is usually done using a filter system of some kind.....reverse osmosis, activated charcoal or whichever...
If it's distilled, it's sold specifically as that....(a more expensive process than most filtering)...
Just to further confuse the issue.....there's also deionized water...which means dissolved minerals are removed....but maybe not other stuff...
Now, even though I know a little bit about this stuff, I don't know which type we're "supposed" to be drinking....
I myself have never consumed bottled water as a product, because of the impact of all of the plastic bottles have on the environment....
I bought distilled water and added the ph drops but how do you know if it's actually alkaline? I tried using the strips I use when I pee but they just looked the same color after they were wet as when they were dry. I don't know if that means it's still not alkaline enough or what.
What you need is universal pH paper....I have some stuff that goes from 2 (way acidic) to 14 (way alkaline).....
My tapwater appears to be at 7 (neutral), a drop of lemon juice comes at 3....
Had it for a long time, so I can't say as to accuracy, but it still changes....
If you know anyone makes their own soap, they may have some pH papers to give you, because alkalinity can be an issue for a soaper....
I got mine at a science surplus place....
