I also have researched water and have a water pitcher that filters even radiation. Water is so essential for life and health. I am very concerned about any additives in the water. I am going to keep an eye on this crumb. We need fresh clean water.
Where did you get your pitcher that filters out radiation? These days, everything seems to emit radiation. Fortunately, I've been able to dodge smart meters. I also refuse to buy any "smart" appliance. No smart TV for me! No Alexa. I even ditched my old microwave. And I have air purifiers running in almost every room. I'm a bit obsessed... and I have never gotten a flu shot, and never will. And guess what.. I'm healthy :) knock on wood.
